Hello-
after seeing multiple questions on "what modem do I use" throughout here, I see one trend in the responses: it depends on where you live, etc....
so to make things a little easier, I would like to start a thread for people to post their modem files they're using, region, and how well it works as well as any other pertinent information. That way 2 people from the same region can save time and collaborate and people from central pennsylvania, for example, will be able to see that the KJ3 and KD1 modems both work in this area fairly well, KI3 not so well, and save other people in this area (and others) the trouble of "reinventing the wheel" trying to find the best modem file when someone in their area already has one working great.
So I'll start
Region: Central Pennsylvania, USA (york/harrisburg area)
Rom: octane v2.0 w/ gingerbread
Modem files tried: KD1 (stock, worked ok except in town for some goofy reason)
KJ3: works well, no issues so far, nice speeds, have yet to test all over the region, will update as neccessary
KI3: haven't had much luck with this one, it works but not as well as the other two from what I could find, but the difference is rather little
those are the only 3 I have tested, I do intend to test the rest of them for this region.
If you have tested modem files on your galaxy s 4g, please post what ones you used, your region, and how well they worked. Rom information would probably be useful too......hopefully this should make it easier for people as we'll hopefully have a single reference for "what works where best"....
I think this is a great idea, but I think we need to set up some sort of standard to judge the speeds. One person's "good" may be another person's "poor" and yet another man's "pretty fast". Perhaps we should use something like SpeedTest.net for both WiFi and network speeds for example. I think having a set standard to judge speeds would make this idea worth while. I think it would be great to know which modems work best and where.
Excellent idea, an agreed standard is key. I've been using speedtest.net app for mine, with about average 4mbps down and 2mbps up on 4g (with a few random odd network errors on upload test), 10+mbps down and 5mbps up on wifi. definitely better than stock ROM.
I guess this thread would be based on the best speeds and reception you ever received?
There's so many factors that determine how good a modem is that I stopped caring, lol.

Well, it really shouldn't be the best speeds, but the average. Maybe try 3 different tests on 3 different servers, throw out the high and the low, and post the middle (or post all three, whatever). That way we're not posting only the best speeds we're getting, which obviously aren't the speeds we're normally getting
Eastern PA here. Ki3 rocks for me. I spent an entire day using each modem, and test the new ones as they become available. I run multiple tests throughout the day with both speed test and wifi analyzer, so far ki3 has been top dog for me. I don't have access to my numbers right now (at work) but i have them all written down at home...

Hello, I wanted to ask everyone's opinion on what is the best ROM/Modem combination. I live in WV (Eastern) so there is a lot of hills so really I don't have any trouble with reception most of the time being on top hills but I would like to have better if possible because it seems the places I need it most I get from "No Service", "Edge", "3G" or "H" and it moves around but mostly on edge. Right now I am running the stock Serendipity 6.4. Any ideas on how to get better reception?
Thanks,
Mods frown on these types of posts. ROMs are very personal and what works for one may not work for another. Radios/modems are very geographically variable. Try looking in the modems sticky in Dev. Lots of good info in there.
You should try flashing different modems and see which one works for you. I'm in the same area and kb1 and jk4 work well for me. But I've been running 2.3.3 for a while now. Good luck!

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!
Anyone else notice new modem not good? Is this a phone thing. I notice wifi not strong as used be could be the ROM or is there trick make sure modem works right or would I be better off with ucl4

Go with the second ICS leak UCLD2 which has a much improved radio.
I am not getting great speeds on the UCLD2 but seems to be getting better as it settles over a few days.
It has been slowing my Wi-Fi as well but shouldn't as the kernal is what handles it. Im scratching my head about it as well but I am investigating it!
I have been stuck on oil rig in BFE and only have edge service, but the reception seems to be better for the phone side of it since flashing UCL2.
I don't know if it has anything to do with ULC2 or not but my GPS signal seems to take a lot longer to lock on?
Some radios work better in certain areas than others. When I had the Captivate there were so many radios available (with varying results based on location) that someone started a map for people to report the best working radios in their area: http://forum.xda-developers.com/showthread.php?t=1227717
I'm finding UCLD2 isn't working so hot for me where I live (harder to get a good signal than UCLC4) but I'm willing to deal with it until a new one comes out.
Whatever you do, stay away from the Note modem that people have been flashing and borking their phones with...

see post #30. Flash with CWM.
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...

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.

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 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.

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.
