Modem Issues w/GB Builds

There's been a lot of discussion about the low WiFi signal from most, if not all, of the Gingerbread builds. Many have speculated that it's simply a display issue and not a performance one.
My wife has a stock ROM (Froyo) and I have the GB build KH1. I did a test comparison of both the WiFi download speeds and the 4G performance.
The KH1 ROM *way* underperformed the Froyo one -- to the point where her stock ROM was at least 2-3x as fast as the KH1 build. 4G performed similarly. WiFi Analyzer also showed a huge difference in signal strength.
I then installed the KH2 modem and tried the same experiment and while it improved it somewhat, it was still woefully lacking in speed over the stock Froyo ROM.
With that said, has anyone found a prior modem build that works better than what's been released recently? This is a huge issue for me and while I love the GB build, to lose that much connectivity speed is troublesome.

There is a thread with all the modems on them, check the bible, you can flash each one to see which is best for you.

I don't think its a modem issue with gb. I've tried them all, wifi still sucks.

Yeah not much you can do here, there will be more leaks..as wifi is still horrible and unacceptable for such an expensive phone..samsung just have to get it right!!

Thanks for the info and confirmation. I was afraid that we'd have to wait for the CM7 release. I've tried several of the modem releases and nothing has worked any better.

yeah its just gb..if its really important just flash back to froyo..but theres good benifits for gb..netflix,skype video calling,better battery life..and all around smoother

I just jumped in neck deep and flashed the latest GB rom KII, Doc's new kernel and was surprised at my wifi speeds. before on stock froyo my wifi was sluggish and intermittent. Now as a matter of fact my whole phone is faster, very snappy. I'm very happy seems like I got a new phone with a duel core cpu
Thanks to all!

Poor Wifi Signal with Valhalla 1.3.2 KJ6 Modem

Hi - I installed the Valhalla 1.3.2 yesterday and then flashed KJ6 modem since i heard KJ6 has better wifi signals, but when i try to connect to wifi i still see poor signal. Is there any fix available for this ?

Not really. I have not noticed any real difference with any of the gb modems.

If you must have wifi, use odexed KJ6 (odin version) and root with Doomlord's method. It's almost perfect imho.
The bad part is you lose cwm & ext4.

KJ6 for me definitely was an improvement, however, it's not as good as Froyo was.

Are you using a deodexed rom?

All GB roms have poor wifi. Once GB becomes official you would hope that type of connection get's better. If not Froyo is still an option if you realy need wifi

Yeah kj6 improved wifi but it still unacceptable compare to froyo and a official gb

has anyone been brave enough to find a modem from another Galaxy S phone with the same hardware? It might be an option. Its only a guess though because I am by no means an expert.

I started on KI3 when I went from FroYo to Octane GB 2.3.5 and then switched to KJ6. both have been around -65db when Im about 10 feet away from the router. on FroYo I was usually around -45db.

The strange part is i upgraded to Valhalla 1.3.2 from Stock leak 2.3.5 KI1 and it was working perfectly. Earlier when i was in KI1 my battery life was amazing used to get around 2 full days now after upgrading to Valhalla it is draining very fast. I have already installed Juice defender and Andreline Tweak v12.

I also have expetienced these issues. I foubd Black Ice was most reliable, followed by Octaine, and then Valhalla 1.3.2. I also find that. Wifi does more poorly on low battery (<35%) but I know voltage should be a constant so there's no rationale to that behavior I can divine. Its not an anecdotal observation though, I ran the DbM timeline and it supported my suspicions. I wonder if this would be due to some software side battery optimizations Samsung threw in.
I eagerly anticipipate trying.the 2.3.6 kernel with fingers crossed.

The modem.bin doesn't control the wifi. If you want good wifi see my thread in the dev section
*the mod only works with 2.3.5 or higher
Sent from my SGH-T959V using XDA App

Tehgy is right about that, I think if there's any optimizations to be had they are modded through build.prop functions and possibly SysCtl also. Unless you have a healthy amount of development knowledge on a coding level, the only solutions are to rely on Tehgy and other more experoenxed developers and/or extensively test various combinations of ROM/Kernel flashes with as much isolation of usage variables as possible.
Do not count out anecdotal use case experiences as irrelevant, the sum of these observations helps developers to locate variance and provides clues as to where to begin searching or modifying relevant code.

Best modem for cappy

I was wondering what the best kk4 modem is? I am running legend blue 3.4 with all their stuff just wondering if there is a better one
Sent from my SAMSUNG-SGH-I897 using XDA Premium App

It depends on your location. You need to do some testing to see which one works best for you, or see what other people in your area use http://soggycashew.weebly.com/modem-location-map.html

Please refer to the link above. Different modems work better for different areas/ROMs, etc.

[Q] [ROM] Ethereal 1.2

hi everyone,
this is actually directed to Jscott, regarding the ethereal last build 1.2
my question is:
I was using your stock at&t gb with root and cwm.
specifically your option 3 in the threar you posted over in development,
a few days ago ive been using the ethereal rom v1.2
ive been experiencing some differences vrs the stock gb uclb3.
is it possible that battery life is shortened with your rom?
could this be because of the kernel change? (stock has entropy's dd, ethereal infuzion core a)
lets assume kernel could be the cause, is it possible to flash entropys kernel into the ethereal rom? would it affect its performance?
lidroid toggles work partially in some cases, like flashlight wont turn on sometimes.
can the rom have issues regarding the response of the screen, in some cases it seems to fail to respond. have to push my finger a lil bit more to the screen.
im very new to this area of flashing roms and stuff. just wanted to say ethereal is very cool, you did a very nice job with this! thanks!

Since you directed your question to..the op of this ROM, question relayed....

Glad you're enjoying Ethereal. I'll tell you a little "secret". Ethereal is Option C from the Odin UCLB3 packages I put together. A few images and graphical values have been changed to make it look more custom, the launcher has been changed to AOSP, and lidroid toggles have been added. If lidroid toggles get a little wonky, as they have from time to time in most custom roms, a reboot should clear things up. As for battery use, I've had about the same for both stock and Ethereal. Most have reported good battery stats on the rom, but your mileage may vary based on how you use the phone and what apps you use. You may notice a slight difference when using Entropy512's daily driver kernel, as it was designed to provide good battery life. You can flash it with this rom if you would like to test. If you aren't comfortable flashing kernels, you may want to give Zen Arcade's Infuse Toolkit a try. It gives the option to try different kernels.

your response much appreciated!
can I flash the kernel same way as in the post you made about using different kernels?
it's impressive it is option c. in performance they have alot of difference, ethereal has no lag whatsoever.
thats why I was asking if I change to entropy512 dd from infuzion, would that affect ethereals performance?

I personally get good performance with Entropy512's daily driver and Ethereal, and you can use any of the kernel flash methods (easiest being SGS Kernel Flasher from the Play store).

I've changed the kernel with sgs kernel flasher, gonna give it a shot how it goes. Where can you see what version of kernel the phone is using? I've tried in settings/ about phone, but that doesnt seem to change. Im not a heavy user like gaming and alot of texting, I just feel, what would you consider good battery life?

You can see the kernel information in Settings / About Phone. The kernel info is the same for both Zen's Infusion-Z and Entropy's Daily Driver since they are based on the same kernel. For battery life, I can get about a day and a half if I hardly use the phone. With moderate use, I have to plug it in when I go to sleep each night. That's about as good as I get for battery life on stock, on UCLB3 based custom roms, and on CM9. This is with keeping the phone in airplane mode and with wifi on when there is bad cell reception. This phone eats up battery when it searches for cell towers and can't find one. I also keep my screen as dim as possible, unless I'm outdoors, keep GPS off unless needed, and keep auto-rotation off unless needed. If I have a day where I use the phone heavily, and the screen is on for several hours at a time, I get about eight or nine hours, but top it off at work or in the car to make it through the day. This is pretty average for most modern smart phones.

Yeah thats right, everything is working quite alright with the kernel. seriously congrats on this Rom, works pretty damn good, i like how fast it is compared to the stock touchwiz based rom.

That's about it. If you like Ethereal, it's worth flashing 1.3 as this is the final release.

Love the mod , keep up the good work

Should follow same procedure as installing a new Rom right?

Yeah, I've seen this also. The only way to make that not happen is if I go in and change the remaining stock icons to match the ones that I've already modified. I'll get to that eventually.

Just fixed this, by the way, and will get an update out in the next day or so. There are a few other things I want to work on before putting out another release.

[RADIO] UCLF6, UCLI3, UCLK4 Discussion

I'm here to discuss these 3 radios, want to hear people's experiences and thoughts on compatibility with ROMs and kernels.
My particular reason for interest is in flashing the King Kangers One .12 Kernel, my current radio (UCLK4) suddenly became (unknown) and my immediate thought was incompatibility, so I flashed UCLI3 back n I was all gravy. Now I wonder if re-flashing UCLK4 after the kernel would fix the problem. I also wonder if (assuming that its actually a compatibility issue) anyone can specify other incompatibilities for kernels and ROMs/versions, etc. Just want to learn and also hear from people about their personal takes on the development as a whole and expand my knowledge.
I do plenty of reading and we all know there's a bunch of stuff to read so covering all of it is difficult. Plus I'd love the opportunity to share the conversation and thoughts with you wonderful people as I progress
I'd like to express my thanks in advance to those who share with me.

ROM: CvD-Nibbles
Kernel: King Kangers One .12
Radio: UCLI3
Recovery: twrp2

Good topic and useful..I don't know why it didn't catch attention..!

Right? I even took the educated and respectable approach. Ahh well at least I didn't get flamed like this is a "best radio" post.
On topic: I have had best luck on CvD's Nibbles 1.5 using uclk4. Ucli3 was horrible and uclf6 was off and on. Haven't tried uclk4 on any other ROMs but cm10 I used ucli3 flawlessly and same on slim bean
Sent from my SAMSUNG-SGH-I727 using xda app-developers app

You mean UCLC4 ? I heard about that radio being good from numerous people, isn't that an old radio came out with the first ice cream sandwich leak ? didn't try it to be honest but might do it someday..UCLF6 was fine with me in data and signal,UCLI3 is bad when it comes to calling and about the same on data..UCLL3 looks promising in both!
PS: Bell's radio MUGLH2 is good on signal and louder call volume..but it doesn't work with the jb leaked roms...

No its UCLK4, its built into aroma installer for CvD's Nibbles ROM. Its the newest leaked radio I believe. I might be wrong but I got the radio right. Seems to be pretty stable. With nibbles in particular it works the best as I said. But I did just read about UCLL3 and I got curious

There are no dumb questions. Just make sure you search first. You won't always find what you need so here goes helpwise. What sort of issues are you having, and what kernel/radio do you have. I'm guessing its all the baked in goodies but just to be sure list your issues and baseband so we can all put serious faces on and make noises like "hmmm" out loud and stare intently at the screen I'm still new to this but I catch on quick and I've been studying all these things. I love it when I can be helpful.

Indeed a solid radio, and my current ROM as well, I just keep having the same issue. APN loss, so no connections. I don't know how it happens. Possible juice defender was the culprit. Haven't had it happen since that got unins. I did a few things though so I can't be sure.
