After browsing the Threads for a bit (and I use the word 'a bit' lightly since I'm limited on time at work) I've not really found an answer for the problem I'm having.
Over the weekend I took the plunge and entered into the world of Rooting and custom ROM's on my HTC Inspire 4G. The ROM of choice?
Android Revolution 4G 5.1.7
The results? Well, overall the phone feels nice and smooth. I've noticed that it lags pretty decently if I'm running certain internet radio apps and sometimes that my screen will go black, my home row (four buttons at the bottom of the screen) buttons will stay lit, and I can't make my phone DO anything. I guess this is a lock up? Anyways, these are all minor tweaks for me, and not a big big deal.
The big issue? My H+ is gone, and I don't mean the fact it just shows an H now instead. I mean the fact in areas where I use to get enough signal to stream music all night, I barely get signal, it drops randomly, or it'll play one song, and disconnect. I have to unlock the screen and restart the app altogether to get it playing again. Rinse, repeat. The speed has been a huge drop too. Standing outside my room where I was getting 1.5Mbps-2Mbps download speeds and about the same for upload, I'm now getting 512kbps download and maybe 80kbps upload...A HUGE difference.
I'm using the radio suggested in the thread for the ROM (Radio_12.54.60.25_26.09.04.11_M2) and I've tried a few others as well, and still see horrible results. Is there any suggestions about this, or is it time to find a new ROM/way back to the stock ROM and Radio?
Thanks.
I just flashed the same ROM coming from Android Revolution HD 4.0 β 4. Since I'm at work I haven't had a chance to flash the suggested radio yet for Revolution 5.1.7, still using the radio from the 4.0 β 4. I would try 12.41.60.19_26.06.04.14_M, I'm still getting the same signal strength that I was with the old ROM with the new.
Link Its in the middle of the first post.
How's the speed with the suggested Radio? Personally I'm a little disappointed with getting far slower speeds after the ROM swap and rooting the phone.
I'm in the middle of Dallas right now, but I'm getting 76ms ping, 5088kbps down and 1283kbps up. Thats about usual for where I'm at.
And on this ROM I don't know if it will even show an H+, mine just says H. Network says I'm on HSDPA...
Nice. I'll have to change the Radio when I get home and hope its the problem. Downloading at less than 1mbps with four bars and uploading at less than 100kbps kinda caps the phone to the point that my (censored) 4 actually looks less than unappealing lol. Did you do anything else that may be different? I haven't gotten the OTA update since the ROM change (from what I've read, that's not something we get anyways?) and I'm assuming that with this ROM we'll only ever see the H and not H+ like the stock ROM has?
Haven't done anything that I think would affect the signal/speed/data/whatever. This was a fresh download and install from about 3hours ago. If flashing that other radio fails, I would try a clean install, redownload rom, wipe everything that needs wiping and make sure to follow the directions exactly. If all that fails search that thread, FAQ's, I'm almost certain you're not the only one that has had this problem.
Its the second time I've wiped clean (even using the suggested download file he has on the thread for the wiping) with the same results, but I'll give it another whirl. Third time's the charm right? I'm just hoping the radio is the problem so that I can move on to figuring out why running Slacker and Meebo at the same time causes my phone to lag like a SOB now. D:
I had signal problem with the coredroid Rom. I am using stock radio. Make sure u flash RIL with the radio u are using. That will improve signal.

This link explains what RIL is and It also has links to RIL with What ever radio you are running. Just match the radio numbers and flash the Correct RIL

I'll give all the advice above a try and see what works out. Either way, if I can get it working, I'll be sure to mash a few Thank buttons. Lets hope this works, 'cause I'm digging this ROM (minus the uber slow down with Slacker Radio) a whole lot.

Well, I'm finally able to work on my phone, and get ready to download the suggested Radio when...File removed?! Hm, guess I'll have to look around and try to find where to download it from.
Okay, I've tried all the above methods, and even standing in an area with full signal (H, though dialing info with all the stars and such tells me I'm in HSDPA) and I'm still getting a download of about 625kbps and an upload of about...Well, 10kbps when it actually works. Any umm, suggestions or is my phone just SOL? I'd really hate to have to go back to the iDevice due to having a hot fast phone that has the connection speed to rival dialup. x.x'
@ Kuronen
I can help you out here, I had the same problem as you. It is because of the build.prop settings in the Android Revolution 4 roms.
If you need to know specifically how to do edit the file I would be happy to explain.
Here are my setting in the build.prop file that gave me 3mb/1.2mb up/down.
ro.ril.enable.a52.HTC-ITA=1 (probably a standards enforcement flag)
ro.ril.enable.a53.HTC-ITA=1 (...)
ro.ril.enable.a52=0 (this disables older type of encryption)
ro.ril.enable.a53=1 (enables encrption gsm?)
ro.ril.hsdpa.category=13 (this is a little higher than the chipset supports)
ro.ril.hsupa.category=7 (supposed to be the highest cat)
ro.ril.hsxpa=2 (this turns on both hsupa/hspa+?)
ro.ril.avoid.pdp.overlap=1 (this stabilized the connection)
ro.ril.enable.3g.prefix=1 (oddly enough, this doubled my speed!)
ro.ril.enable.hep=1 (I don't know what this does, it doesn't seem to make a diff)
ro.ril.enable.sdr=0 (this is to turn on software data radio, should not be needed)
ro.ril.enable.ucsq=2 (unkown)
ro.ril.enable.gea3=1 (this enables GSM encryption)
ro.ril.enable.prl.recognition=0 (if you are in china leave this as 1)
These settings give me good speeds. In other forums the 3G prefix command is supposed to only "label" the connection as 3G, but I have confirmed that in my area enabling the prefix actually doubles my downlink speed. So it must be flagging something elsewhere.
To edit the build.prop file after you have flashed to your phone you will need the android SDK kit. In general you have to log into the shell of the phone and remount the system partition as RW (read-write) then you can push the build.prop you edited and reboot. Just remember to edit the text file with an editor and uses unix style line feeds (like notepad2 ).

I'll have to give this a try when I get home. I've tried like 3 roms now all with decreasing luck, as well as a handful (including stock) of radios. Though, unless I can figure out why using Slacker Radio causes my phone to respond so slow that it takes a few minutes to move swipe screens, I may end up going back to stock anyways. As much as I don't want to.
Though, I'll give this a whirl first, and hopefully it'll fix my speed issue. I can give up Slacker if everything else works amazing, more so the batter life lol.
Edit: A walk through, or a link to one, would be utterly amazing. After looking at my SDK folder I realized I have no earthly clue how the heck to use it. All I can really do is find virtual devices. D=
On 5.1.6 and 5.1.7. All is fine here, including signal.
I get ~5mbps down and ~1.2 mbps up.
I see your on the Same rom as I am. I haven't fully read through this thread but I'm sure something in the mix u did might have made it to act funny. I have the same rom flash the recommended radio and flash The ril aswell and there seems to be no problem on my end. I'm around 2.5 megs down and 1.3 megs up. Also your phone SHOULD be much smoother and I don't seem to have any glitches on my phone. Also if u can setcpu off the android market that would help the smoothness of your phone with that rom. And if possible what's your build prop? Messing with that could improve signal but I wouldn't reccomend it. Let that be the last thing you mess with.

I've tried re hack-kitting it, different roms, radios, stock radio with different roms, etc, etc. Kernels updated, RIL and all that, and still get
150kbps download and 70kbps upload.
Massive huge drop from stock pre-root and all that where I was getting closer to 2mbps download and 1.5mbps upload. Which I can't seem to get anymore even with the stock ROM/Radio. Guess its a sign that I should've left things as they were.
I'll try to figure out how to edit build.prop but several hours of googling have given me plenty of 'oh just edit this!' threads, but nothing on detailed instructions on how to get to build.prop to edit.
Since I can't go without a phone for long (on call 24/7) I don't have the ability to sit down and spend a few days making it into a project while I go without a phone...So I guess until I can find a good tutorial on how to edit the build.prop and see if that's it, its time to go back stock.
No point in having a bad-a custom rom that makes it fast, sleek, and uses less battery if using the phone itself isn't enjoyable. No good net, means no good phone in my opinion.

I had the exact same problem. To be honest, I liked android revolution, but the speeds and signal were a BIG issue for me. I ended up going to a stock ROM that was rooted. I'm back to H+ and decent speeds. I was using CM7 before I loaded up android revolution and it was great. I only switched to revolution because I missed Sense.
I wish I could get my original speed back. D: Honestly it seems like I've lost out since I rooted my phone. I can barely push 1mbps download and 200kbps uploads now. And thats after completely unrooting and restoring my phone to stock. And I still can't play any Pandora/Slacker without opening my phone up over and over and fighting with it to connect. In a place where I use to stream for 8+ hours no problem.

hi-
I just installed Octane to my galaxy s 4g after much work, research and reading through these forums. Everything is working phenomenally, I'm running gingerbread, have screaming speeds, and fairly decent 4g data connection (confirmed) and my phone boots faster than I've ever seen it, awesome work.
The problem is that wifi is not working that well. The range is horrible and it will only connect to wireless G routers, and absolutely will not even connect to any N routers, it just simply scans, connects, scans, connects, etc....
I have tried multiple modem files, the default that comes with Octane (which I believe is KI3, I tried KF2, as well as KJ3, all with same results, and will be attempting KD2 next (the one that came stock on the phone, I believe), which I expect the same results as I was running the KJ3 modem prior to moving from stock rom to Octane, with no issues which tells me it's likely a problem with how the new rom handles N networks, but if anybody else here has an idea on how to fix this, I'm all ears.
Like I said, everything else is working just great, so I know the rom installed properly and even got gingerbread working, however is someone doesn't believe me that I actually can follow instructions, the links for the guides I followed are below.
Rooted, installed cwm
backed up my stock rom, settings, etc, twice using cwm (just to make sure) and backed all sd card contents up to computer
attempted install of octane per the forum, http://forum.xda-developers.com/showthread.php?t=1305145
failed due to gingerbread migration issue, fixed per the gingerbread start up guide http://forum.xda-developers.com/showthread.php?t=1223765
and of course for completeness, I did read over/follow http://forum.xda-developers.com/showthread.php?t=1122508 where applicable and had a nice look over the bible at http://forum.xda-developers.com/showthread.php?t=1117554 and a look over http://forum.xda-developers.com/showthread.php?t=979109
and that, I believe encompasses about every useful and up-to-date bit of pertinent information that I could find, and remember using since this adventure has taken quite a bit of time over the last few days.
So, please don't ask any dumb obvious questions like "did you set the mounts properly" or "did you wipe the cache first", because I did, if I didn't the rom wouldn't even be working and I would have a different issue, and please don't flame me if this happened to have been answered 6 months ago on this forum, google and even this forum search can only do so much and I did make every reasonable effort to find an answer first. I may be new to these forums but not to technology...so thanks to all who are able and willing to offer any useful suggestions/advice.
Sorry, but that last part of your post was arrogant as hell. You should consider not putting that there if you want help next time. Most people that could help might just be put off by that.
On topic, wifi is a known issue on ask of the GB ROMs, which is why every leak practically has the question "how's wifi". We're still waiting for a leak with all problems solved.
thank you very much for your reply, that was exactly the type of information I was looking for.
As for sounding arrogant, I apologize and did consider that when writing and tried to make it sound less arrogant, problem is I have had more than my fair share of experience on these forums and I find it tends to waste a ton of time when people don't bother to read my post and ask me obvious questions, or just simply insult me by talking down to me like a kindergartener. Now I understand there's a lot of noobs on here and such, and I apologize for my frustrations in getting responses and any hurt feelings. Unfortunately I don't know any better way of getting across that I'm not an idiot, can use search and google, and can follow directions....
Glad I could help.
However, if you're super dependent on wifi, you should probably go back to Froyo instead. IMO, the speed difference in GB is worth the poor wifi signal (although my wifi doesn't seem to have problems).
That wasn't meant to be anything offensive to you, btw. Just wanted to give you a heads up. Unfortunately, some people here jump at the chance to flame.
yeah, I'll take the speed anyday, having my phone up and ready to go in 2-4 minutes versus the 15-20 it used to take is definitely worth it, and 4g is working well enough I can live with being stuck on 4g at one end of my house...
and yes, people love to flame, on xbox we call them telephone tough guys, all the same though, a hallmark of the internet since the early 90's, man that makes me feel old....
You could also try switching out modems to see which one would give you the best service too.
Pardon my lack of proficiency on the subject but what tools and or apps do you use to test the wifi on our phones? I hardly use it so I really haven't noticed any difference since flashing custom ROMs. I think the only time I connect is to use the Google TV remote app to interact with the TV. I understand testing with different routers for the B/G/N connections I was just curious what tools you use to measure signal strength and throughput?

Nice, thank you sir. Only thing is I don't want to go back to stock or even Froyo to see if there is a difference lol. But with this app at least I can see just what my Wifi is doing.

Probably won't be any difference between modded and stock. Since the rom modders aren't modifying the modem.bin.
But going back to Froyo, you will notice a difference. It is much better there.
Wifi is probably the reason they haven't dropped GB source yet (amongst other stability issues).
[FIXED] wifi on galaxy s 4g fully working WITH gingerbread
IT WORKS, IT'S FIXED!!! WOOT!!!
yes, running gingerbread/octane on galaxy s 4g, have wifi on both N and G networks, secured with wpa/wpa2 psk. Typical setup in any home and it works!! not the strongest signal on the planet but I have access and screaming speeds (4g speeds are off the chain with this new rom compared to stock, better performance probably has everything to do with it)
so, yes, a router reboot and a couple modem file flashes later and viola, everything works.....using gingerbread. Would add a signature to show what I"m using if this site would let me, but for now I'll post it here:
Phone: samsung galaxy s 4g (SGH-T959V)
firmware version: 2.3.5
Baseband version: T959VUVKJ3
modem: KJ3
Kernel version: [email protected] #2
Build: Gingerbread.VUVKI3
Rom: octane v2.0 from http://forum.xda-developers.com/showthread.php?t=1305145
hint: if you choose to install the rom, be sure to install the gingerbread startup pack first!
from the above responses having wifi, 4g, and everything else working WITH a new rom and great performance has had an issue, I would like to say at this point everything is working great all around, no issues whatsoever. Total awesomsauce!
So let me start off by saying I've used both stock Gingerbread, and ICS probably about equal time each so I'm used to the signal behaviours of each.
My signal was always bad where I am at University and all of my flat mates had great signal (3G, HSPDA). I took my phone in for repair and they replaced the main board, they also reinstalled Gingerbread, even though I had already S-ON'd unbranded etc etc.
My signal was great and I could use my phone properly again, internet everywhere and it was amazing.
Now I have my new SD card and I've just rerooted S-OFF'd etc and now my signal is playing up. I thought well hey if ICS is coming out soon why not just install it now anyway, because if my signal is bad on ICS i'll know it.
My question is what is your signal like since upgrading to ICS, if you have that is. I'm averaging 2/5 bars of HSPDA whereas before I was getting 2/4 HSPDA, and the overall loading is slower.
I'm running latest Insert Coin with the firmware from the user-friendly firmware thread.
Any help/tips or insight on the matter is greatly appreciated, also this is my first post so I'm sorry if I missed something.
tl;dr, since upgrading to ICS signal is crap, what's your signal like if you run ICS.
Edit 1: Done some things and found stuff out.
It seems to be for sure that ICS is to blame for this, although I'm getting weird results. I installed the ROM from MrT's (I think that was his name) and my signal did improve slightly, from 0-2 asu up to 6-8 asu, although it still fluctuates. I've tried ARHD and IC both have bad signal (definitely NOT the developers fault I was just saying).
I am gonna try the OTA next and see what the difference is. I mustn't be the only person who has much worse signal on ICS. There is zero point reverting to S-ON and going to GB, because we'll all be getting ICS this week or next anyway.
Will keep thread update in case anyone else has similar issues that they wish to fix.
Edit 2: I reverted to stock GB and then used the OTA file so now I'm at official stock ICS untouched. The signal is improved although still not as good as GB. I will wait until the release and see if I receive another update and then edit the OP again.
I also have bad reception and voice calls bad sound on ICS , I didn't use gb so I can't know the difference but on ics is crapy
Bought mine used, and the seller had just s-offed it. Ever since I've had it, all radio reception has been terrible in comparison to my N1, the worst being bluetooth, closely followed by wifi. Cell/data reception is acceptable but still not as good as the N1. I've just ordered a "new" back cover from Ebay in the hope that it's a hardware/antenna issue, I have reason to believe it might be based on the erratic nature of the bluetooth problems.
Should have mentioned first, I'm not running a 4.0 rom yet, I've been flipping between the original T-Mobile Sense g/b rom and CM7. Bluetooth's bad on both, but I've got a sneaking suspicion that wifi is better on the Sense rom, although that might be my imagination.
Thanks for your replies guys.
I will try installing the OTA file, maybe it has something different to the firmware and ROM I am using, it's worth a try anyway.
It's also worth noting that signal does go down upon picking up the phone into my hand. Right now it has 3/5 HSPDA but when I pick it up in my hand, 5 inches higher than it was, the signal drops to 1/5.
I changed firmware to 3.32 and it's little beter now. I think it's radio software problem

Yeah I'm using 3.32 but it's actually worse. I've tried a few different versions I've found around the forum and they're all the same. Signal is fine when not being used but goes down when I use it or hold it in my hand.
I hope the official OTA is not like this or I will have to send it in for repairs again or get a new phone altogether.
Mine is bad in ics too. It was ok. at gb.

Thanks for sharing, how much worse is it? For example with me I used to get about 7-10 asu in network section of settings, now its 0-2.
I guess I will try to cope until it is officially out for the Sensation in the UK and then after I can go into the shop and send it in for repair (second time).
I have the same problem before I used to get 2-3megabytes on speed test and now I'm getting half a megabyte and from the same place in my room where I used to have full 4 bars now I have 4/5 bars and I can't even buffer YouTube video

I have to say that my reception is worse on ICS. I was using gingerbread on sensation, from new, for about a month before I made any changes to my phone (root, s-off etc.) I would get a constant full 4 bar reception, it would never drop. Now on ICS, signal strength flits between 3 and 4 bars frequently, sometimes dropping to 2 or even 1 very ocassionaly. It is pretty annoying.
YES. i am experiencing the same exact problem. i have to say ics has been pretty disappointing. my signal in my room used to be 1-3 with an average of 2. Now its the same, but wit frequent drops to 0. Cmon. crappy browser, bad signal, isnt this supposed to be final version?
ok my receiption is worse at my office.. Not only worse can describe but i kinda suffer cuz of my connection. I think its related to the radio and i should try another one cuz its really annoying
im on ics, suffered the same fate, maybe this is due to DEATH GRIP?

Obviously I can't speak for everyone, but it is definitely not due to death grip with me. I can just leave the phone stationary, not even touching it and I can see the signal strength bars going up and down. I would really like to know what is causing it. I used to have perfect signal on Gingerbread.

i just wish its the ICS problem... i really love the phone, but im a little bit dissapointed as what i see on the google regarding death grip.
Same problem in my S2. I'm in a place which is like a Faradays cage, so signal fluctuates from 0 to 4. My new phone improved performance a lot because signal was fluctuating more quickly. I thought it was the hardware, I was very happy, but after updating to ICS it happened again. I think it's a kind of watchdog for signal, which is slower in ICS than GB. So should be a way to speed it. I decided to go back to GB but I can't: factory reset doesn't return phone to 2.3.5
First off I apologize if there is another thread about this but all I found when searching was a general "best rom", and one related to battery life.
Personally I would like to know opinions on best rom for connectivity only. I live in a strong 4G area but whenever I am in my basement I get spotty connectivity, drop calls and such. I have been on the CM10 nightlies crack flashing since the boot-loader was unlocked. I love CM10 just wondering for basic call quality, does someone have a different rom preference for call quality?
Again mods I apologize if this is out there... but i couldn't find one for call quality. I realize this all depends on the baseband and such which Samsung is infamous for theirs. I just feel like even a slight better signal would make a big difference for me considering generally it's good connection.
Also my office is in my basement and I make a lot of calls and I'd prefer to keep it that way if possible.
Any thoughts are appreciated.
I'd actually like to know this as well. I recently switched from using an iphone to a Samsung Galaxy S3 and the difference with this phone is there are so many different roms available, I don't know which one is the best whereas with the iphone there is usually 1 main jailbreak and everything else is provided by cydia.
Like you said, this mainly is based on the radio and not on the Rom, but i agree there could be some minor differences. Your best bet would be to try a couple out and see how they work in your office. I personally am running jellywiz and my signal is rock sold and i work in low signal areas a lot.

If you search the forum there is actually a main thread for best rom overall which may help you more since it doesn't seem your only concern is call quality. Sorry I don't have the thread name but I think if you do a forum search for "best rom" you should be able to find that thread.

I actually planned on doing that and testing them out on my own, I was just hoping someone may have some tips on one they have used in areas such as a basement or a place they know they haven't always gotten good service but have found a rom that works great for them as far as call quality. Such as your example of jellywiz, I will certainly give that a try and see if I can hold a higher consistency for call quality. Thanks for your input!
There are definetly differences between ROMs relative to battery life... different versions of the same ROM can be quite different.
I've been using Jellywiz as my DD and it's been great. I really liked RLS4. I've updated to RLS5 this morning but my battery life has declined greatly. I've also gotten one reboot. I'm sure the dev will have it fixed in the next release (the Devs on the Jellywiz project are top notch).
I also liked Synergy quite a lot... It's not Jelly Bean, but the battery life was great and very stable!
The best thing you can do is try several different ones... Let the ROM settle for a good day or two before coming to any conclusions...
Good luck...

First off I apologize if there is another thread about this but all I found when searching was a general "best rom", and one related to battery life.

Without getting too granular, stock based roms have the best reception. Rom's where the RIL has had to be tweaked, such as CM, MIUI, JellyBean ports, and cross carrier ports are more likely to have radio issues.
Then, there are different radios you could flash. In my experience with many devices, changing radios has never had much of an impact on radio reception. Different radio versions generally fix bugs, and things like 3g/4g switching. For instance the latest stock radio for our device (VRLG7) fixes the "no SIM" bug. I am using that and it has worked great for me.
Generally though, I don't think actual reception (mostly dependent on hardware) should vary too much. Usually it's reliability that can vary. "Bars" aren't always an accurate indicator of reception either, signal strength in dBm is.

Sorry... I got lost in an unrelated thought (battery life)....
The service side appears to be pretty sold from the ROMs that I've personally tried. Not sure you'll find a big difference here in real world performance.
CodefireX is getting me the best service I've ever had. Several other people in the thread seem to be experiencing the same thing.

I have not seen the 4G indicator since flashing a week or more ago. I have tried aokp, cm10, and root66.
Not sure what to do. The phone works fine otherwise. All these are great but I would never have gone this route if I had any thought that wireless capabilities would be reduced. Any ideas on how to return to 4G would be greatly appreciated.
Out of all the 4.1 roms out there, JellyWiz's wifi/4G/3g is the most solid one. Very stable and good enough to be a DD.

I already try to flash CM7 and CM9 mtd(KG4,KG6,KD1) modems to see if that help and nothing , always weak wifi reception.. I need help with this...What can i do to improve signal reception ?
Wifi was fine with stock rom 2.3.6
AOKP Milestone 6, build 5 is a great and fast rom but only two problems weak wifi and a little battery drain
This has been discussed a bunch.

thanks for the quick reply
Why this happens ?
its something with the kernel ? or drivers why no use original ones ?
That's a question for "Google"
Actually if you read the threads taking about this specifically the one by jeffsf he has a theory that Samsung knew many of the devices had crappy WiFi hardware and that is why the device had tons of leaked builds. They kept releasing then in hope of fixing the reception and ultimately just faked a better signal.

I dont know how erik did it but the ics stock imm76l rom has excellent wifi signal. Other then that its what the guy b4 me said

I saw that the big impact with wifi is make by the kernel you install, cause switching modem always the wifi signal is the same but when you change the kernel you see some diferents.
There is no super duper trick to get better wifi. What Samsung did was modify the data file to reflect a higher level. It is a visual trick and one that tricks the OS into thinking the signal is higher also so it does not disconnect as much.
What erikmm did before is change the signal bars from a actual representation to a false reading that made people think they had a better signal. Turn off the bars and use dBm readings and you will see the real signal.
This phone has a really crappy radio reception and there is not much you can do outside of what samsung did and make the signal bars read I higher rating. I think it was jeffsf that said the best solution would be to hack the wifi module and make it read all signals at a increase of 5-10 dBm so it wouldnt drop the wifi so often.

What file do i have to edit to get a fake wifi signal read and avoid disconnecting ?
I actually didn't do what eollie said to trick people I did it because of information another dev told me then I gave it a shot I saw improvements for me and thought it might improved but again if it's not you don't have to flash it or complain. Source is out do instead of complain that something isn't working or a mod isn't 100%

Show me where I said you did it to purposely to deceive people.
Furthermore at the time you where posting those roms there was NO source code to edit.
If you are still doing that code modification then you are now purposely deceiving people.
To clarify if people think I was saying erikmm did it purposely then you are wrong. I dont know what his intentions was initially.
First off, I want to be clear, I don't know what was/is different in Erikmm/Beastmode's ROM. At the time it was released, source was not available to examine, and I haven't dug into what has since been posted. I also hypothesize that Samsung was, among other things that T-Mobile probably wanted them to change, tweaking the "calibration" of the WiFi in the various leaked releases and that the "nice" version wasn't in the final release. Considering that the "official" release modem has problems with long SMSs, it wouldn't surprise me that the low RSSI numbers reported weren't caught either. I don't work at Samsung or T-Mobile, so this is my personal speculation and opinion of a likely scenario.
I have tested WiFi pretty extensively and it is my personal belief that the RF portion of this phone just sucks; WiFi, GPS, and quite possibly Bluetooth, but nobody has complained about the last one. Unfortunately, the leaks were hosted on sites later shut down by the FBI so that getting those versions to examine as well was not possible.
If you want to "fudge" the signal levels, the details of one way to do it are in the linked thread. It will require you to create a build environment, populate it with the source of your choosing, edit WifiManager.java, and compile at least the framework. It could also be done within the kernel driver. Since I find that levels below where the current crop of ICS ROMs believe are "no bars" I don't get more than around 1 Mbps over WiFi and I do generally have decent T-Mobile signal, I just use my carrier for data when the WiFi level is low.
