I just i have a few SGS's and i just installed 2.3.3 on one of them and the problem is it disconnects from the wireless network when the signal gets low.
Side by side the signal levels between the the 2.2.1 and the 2.3.3 units have the same db level, but the 2.3.3 will declare the signal strength is too low and disconnect alot before the 2.2.1
Correct me if im wrong but this version of gingerbread uses the nexus s kernel right? And i've seen lots of complaints about weak 3G on those phones, and google has given up on making a fix.
Any help/insight appreciated
I know, i wave the same problem, it would be nice to know why!
Hi,
what settings do you have in settings->display->energy savings (o sth like this - I am using polish version). There is an option to save energy based on LCD, but... it saves energy probably in more than LCD areas...
When I have bought the phone - I was very confused/upset when my SGS can not use 3G nor HSPA... instead of H displays G (or sometimes E) on connection icon. I suuposed it is broken, when compared with my collegues phone (he had H icon)...
Than I found the solution - switched off energy savings, and than my phone started works well with High speed connection - chech this out...
regrads.
ps. I am using android 2.2
ok, for america its call power saving mode, i'm gonna try it to see
Edit: I try and doesn't work for me...
FIXED
I found a really good fix that has been working awesome. I went and installed a new modem kernel using clock work mod.
I get great signal (haven't lost signal yet), gps, im always connected to data.
Just go on here, download the appropriate kernel and install.
My favorites are I9000UGJL2 and I9000XXJVK. Play around, see what works best in your area.

I'm having this weird issue with my galaxy s. The weird part is that over the last couple of weeks, reception has been zero in a period of time that's been steadily increasing. I've been able to restart the phone to fix it, until yesterday when I couldn't get any reception at all.
But wait, there's more! My sim card works in my girlfriends gs2, her sim card works fine in mine. So, it's only the combination of my sim card and my phone that gives me no reception at all. Also, what could be causing reception to steadily degrade to the point of none at all?
I'm running the team icsgs rc 4.2 with semaphore kernel, but I couldn't post in that thread because of my low post count. So, what I'm thinking is that I should try another modem before I try to wipe and perhaps install another rom. My question is, do I have to use Odin to flash a new modem, or can I just use cwm? Anybody have a suggestion for a particular modem?
So, Ive flashed the KF1 nexus modem, no change at all..
The only thing I haven't tried now is going back to stock rom... Anyone?
I have problems with Nexus S modems (that are so popular last weeks). For me the best modem is original JVU (the CM version). Try with that modem (if not with it already).
Try with the original build, because that reminds me for a hardware problem. You can debug the problem with experiments. Try everything before going to service.
No EDGE/GPRS signal
Hi!
Because I cannot post in development section, I'm putting this here...
Last week I've tried 9 ROMs and different modems and the problem was always the same...
When I'm on UMTS/HSDPA signal, everything works great, but when I'm on EDGE/GPRS signal, I cannot even make a call, or send a message.
This problem is happening to me for the last two weeks... :-(
ROMs tried: teamhacksung's CM9 ALPHA for Galaxy S (BUILD 17, 16), Team ICSSGS RC4.2, AOKP Milestone 4, Build 28 (now using), Dark Knight 3, 4, Elite V9.0
Kernels: Semaphore ICS 0.9.5b, Devil Skorpion Kernel, Midnight ICS 0.9.0-2-HUGERAM (now using), and the ones which comes with ROMs
Modems: XXJVU, XXJVT, XXKF1, XXKD1, XXKB3, AUCKF1, XXJVK, XXJVO and now I'm using XXJW4
When I flash DarkyROM JVU-RE with Odin everything works fine. :-S
So.... I think the problem could be in the ICS ROMs or kernels
If anyone knows how to solve this problem with 2G networks, I would be very grateful.
p.s.
Also, I find my SGS very often bootloop without possibility to enter CWM when I'm flashing new ROM.
And I found a solution for those bootloops, because I'm tired of flashing with ODIN a new GB ROM constantly... after bootloop, I use FixRecovery and flash it with Odin, then enter CWM and install Team ISCSGS RC 4.2 which only starts and make boot image and flash new CWM, so I can flash other ICS ROMs...
Why I'm telling this? - only because the devs could see if they can make other ROMs to start with flashing like Team ICSSGS RC4.2.
Sorry for my bad English. :-$
Edit: @adytum
I have also thought that my SIM card was a problem, so I've exchanged it. Didn't help....
At first the problem was like yours...
Will attempt to install the original stock firmware today (boooo, downgrading from ICS ), but I have my doubts. My service provider have started technical problemshooting at their end, but I have my doubts there too.
To add to the confusion, I discovered that 3g and data traffic works fine, wireless works fine, but calling doesnt work at all. As mentioned, if I put my sim in an other phone, or another sim in my phone, it always works.
I just managed to make it work. In test settings, INFO part (*#*#4636#*#*), after 5 times setting WCDMA only, my phone works only on 3G networks and now I can communicate because it doesn't switch to 2G...
But, I would appreciate if anyone find out solution for problem with 2G.
I hope that this isn't problem with my phone.
As far as your problem, I would try to reinstal the modem, because after trying a lot of new ones, sometimes it just doesn't recognise which one is instaled. JW4 seems the best for me...
Sorry for my bad English... :-(

Here is link where you can get JW4 modem. Flash it through CWM, reboot and check if that will help.

If I could hug you, I would! This modem seems to have solved all my issues! So, yes, our problems are probably related to eachother and to ICS. Never got around to try stock or darkys rom, but I'm guessing that would have fixed my signal issues too.
A million thanks to you! (Now I'm just crossing my fingers for stability and that this is not a fluke!)
Well, I'm glad to see that it works...
For me, JW4 have the best signal, and is very stable. And, you know, I've tried almost all other modems, and they were all pretty much the same.
I wouldn't tell you about that modem if I haven't seen that I have HSDPA reception (-95dBm) in the places where I had very poor 2G signal (-103dBm) , and no 3G signal (-111dBm) at all before.
Sorry for my bad English....
Have you tried if other sim cards work in your phone, or your sim card works in other phones? If so, I'm thinking that these issues have something to do with the service providers not being up to date regarding newer android versions. That's really the only logical conclusion I can draw.
I did call my service provider earlier today, they were as stumped as I am, but did suggest to try connecting with 2g and 3g enabled respectively.
By the way, your english is just fine
Well, I was working as tech support at my provider (until last month), so everything is fine with network and signal.
Also, first thing I did was to check SIM card and it is OK. I even exchange my SIM because it was 5 years old -just in case...
Everything works great in other phones, but in my phone only 2G network reception doesn't- even with other SIM cards...
That is very weird, but, I finally managed to set only 3G so, everything works now, but with very poor signal in places where I had EDGE coverage before.
I even thought that could be a problem with my device, but when I flash GB ROM, everything works, so I'm thinking that it only could be a bug in kernel or ROM.
I didn't see much people complaining about this, maybe only because they are constantly on 3G...
I don't know...

And...
Btw, service providers have nothing to update or upgrade with signal, because it is only frequencies they have to maintain and base cell as root. That's why we use SIM card which help our phones decode signal.
Only thing that is up to providers is maintaining the level of signal and its communication with central station, along with base overload in urban areas.
Sadly,
In 98% of problems, it is up to SIM card, device or software on it.
When the problem is up to service provider, everyone in that region- on the same base cells, have it. :-(
So, obviously it can only be ROM/kernel problem or device(hardware) problem. :-(((

Obviously the main difference here is that the only thing that ruined reception for me was the combination of my sim card and my phone, every other sim and phone combination worked.
You probably have more extensive knowledge about this than I do, and you're probably right inducing that it is a rom or kernel bug.
In that case, there are two options;
Maybe SIM card didn't set well, or SIM card is damaged.
You can try to see if it is damaged or has something on it and clean it. Otherwise, if it is damaged or just won't work, go and exchange it. It takes just a 5 min. And if you tell that SIM stopped working, they won't charge you anything. And, after that, you'll be sure that SIM works.
It also happened to me in the begining, and I was wondering why my SIM won't work only in my phone. Then, I place it in my old Nokia and after 2 days, I couldn't talk with people and the signal was OK. Then I exchanged it, and everything was OK.
Now, obviously I have a problem with a phone. :-(
Maybe it is a message to me to buy a new one... Note, maybe... ;-)
Anyway, I hope that I've helped you.

Seems I was a little too quick. Problems started again today, but I've managed to fix it for now..
I installed jvu from odin as per the first post in the elite, ICS beta 8 thread. Found that everything worked fine in jvu, and now it also works fine in ICS.
