Hey
For the past month or so I have been playing around with a few builds of ICS for captivate. I started to notice that whichever build I used whether it was teamhacksung or miui I didn't have 3g. I changed my APN multiple times, tried different radios and it go to the point when my signal in my basement (where I get crap for signal) showed full bars and 3g except the speed was terrible. Is this a common issue? Anyone able to give me a hand?
I just recently went back to my old backup of CM7 and my 3g works flawless.

Since it's not fully developed yet, there can be random bugs like that. Try a factory reset and a full reinstall. If that doesn't work, you may have to try going from stock

i'm having some what the same problem but with H20 setting not working right. i get talk and text but no internet or mms, and even the setting disappear after i save then
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. :-(((
Sent from my GT-I9000 using XDA
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.
Hi Experts out there,
I have been having 3G mobile network issue with CM7 base ROM. On certain location, I cannot download and make or receive calls. my 3G icon arrows show upload activities but no download happening. My ISP name (Maxis Malaysia) showing as normal. I upgraded to CM7.2, tried Kang ROM, preshoot kernel and change new SIM card but doesn't help.
Disable and Enable the 2G only a few times might resolve the problem for a while. The may come back again as long as I am still at the same locations.
Anyone has any ideas on this problem? ROM or Kernel issue? Recommendations on solutions? Thank you.

It's not the phone. It's signal coverage that you're having problem. Try another location and see if that helps.
I have been getting full bar signal strength on the icon. If connected (after a few tries of enable / dissable 2G only), the connection will be good for a while (some time quite ok for hour). The connection on 2G is 100% stable and reliable. If 3G is weak, it should automatically switch to 2G without issue right?
Thank you for the reply.

No. The problem could be with internet access of the specific UMTS base station that you're connecting to at that spot, and not with the connectivity between your phone and the tower. In any case, it's not your phone, it's the base station, and there's nothing you can do but complain to your cellular carrier.
I have checked with friends (iPhone, Android, BB,etc) surrounding me on the same location, no one is complaining the same problem. That lead me to confirm that its my N1. The worst part is I cannot make or receive calls. I have been missing many important calls...

When did you have this problem? After or before you updated to the latest version of CM7.2? If after then I suggest you do a full wipe and format system and then reflash the ROM. Or you could try to flash a standalone kernel and see if that helps.

Another option would be to flash a different radio. Try to read the radio section on Nexus One thread for more information
I just flash MIUI ROM and will put it to test tomorrow. Hopefully it will be fine. If not, will try to flash different radio. Thank you for all the replies.

Here's a couple solutions:
1) Go to settings>wireless>mobile networks >access point names. Look and see if an option called "Simple" is ticked. If it is, tick your network name instead of Simple. For example, for me, I have T-Mobile; so I have T-Mo ticked and not Simple.
2) Try flashing a new radio or ROM. I highly doubt this is your problem but it is worth a try. Try the .08 version radio or the .12, whichever you don't have.
3) Go to your carrier's store and see if you can get a replacement SIM card. I did this once and they gave me one for free. Just say you are having connection problems and you think your SIM is cutting out. My N1 once fried a SIM card. Just re-read post and seen that you did this. I would highly suggest you try my first option as I had a very similar problem and solved it that way.

SORRY IM HAPPY CAUSE THIS DOES WORK EVERYTIME DANG T-MOBILE GET AT&T TOWERS btw HAPPY EASTER EVERYONE leave me a egg
I have tried MIUI ROM and latest Radio (5.12) for passed few days. The problem still remain.
The new radio giving more stable 3G connection many locations but lost 3G connection on the previous problematic locations.
Really not sure what to do with it now. I have tried everything that is known on the web.

There's nothing you can do. It's between your phone and local base station.
You didn't listen to me earlier, I guess now you will.
It is sad that nothing can be done. The phone should at least switch to 2G when 3G is not available, but my N1 stuck there causing me loosing voice and SMS capabilities. This is fundamentally wrong on the phone.

Hi all,
I'm using latest MIUI ROM atm and love it. however there's a problem of the signal sign which stays on G all the time unless i'm doing any data-related task such as browsing or facebook. at that moment it will quickly change to HSDPA.
not sure if it's a feature or a bug by MIUI?
i have used trinity, coredroid and icecold, they're all good staying in H/3G
Just wondering if anyone else experiencing the same issue with MIUI rom?
I already tried the 27/28/29 radio as well
thanks for the replies

Does this happen everywhere or only in certain locations?
am sure you are aware that gprs/3g is dependent on the network strength.
so it could be cos of a low signal strength area.
since you have tried a couple of radios, try any other rom & check if the problem persists
My phone behaves like this too. But I believe it's carrier specific because when I was using the previous operator the signal always stay in H. Once I begin using current operator, the signal stay in 3G and will switch to H if I access mobile data.
Hi all,
yeah I did try other ROMs and it works alright (trinity and coredroid + icecold)
with the MIUI, the problem persists everywhere even when I change the radio
very hard for me to change MIUI because of the feature and the smoothness
now I set it to use 2G only to save battery
I guess it's not a feature in MIUI since changing between GPRS/HSPA drains the battery?

Actually you can try changing some settings in /system/build.prop. Look for these two settings:
ro.ril.hsdpa.category=6
ro.ril.hsxpa=2
If they're of different values, change them, reboot and see if there's any difference. Don't worry, if anything goes wrong, just change them back.
Hey sup everybody !
I have tryed all of the JB roms out there, but they all seem to have poor wifi quality
can any one confirm ?
thx
Sane here.
I'm not sure exactly what causes this but according to my phone I definitively get worse wifi through JB then ICS and GB.
From what I've picked up the way the phone picks up WIFI has little or nothing to do with the ROM you have installed. Perhaps since JB is more recent and used on the phones with higher specification the wifi picked up on our S's is the same as before but measures differently through JB?
not agree with you .Please flash Nexus Radio KF1 zip file from CWM or reflash cm7 JW4,JW1 radio files.

"specification" nor modem has anything to do with wifi strength
Same here, better WiFi signal strenght on ICS, MIUI GB than JB (doesn't matter stock or CM10). Tried all JB roms from xda, same problem.
Agree!
I don´t know... Maybe Radio files have to do something with that?
How can I find out which one I should flash?
I tried wifix and wifix manager , but nothing changed, this problem is so annoying I guess I'll get back to ICS or GB until they fix it

Modems/radio files have nothing to do with wifi...they are separated modules.
The wifi module is in the kernel. The right modems just give you better signal, with better signal, comes better battery, and i think it has something to do with the gps, but i`m not sure in what percentage.
WiFi was not working at all, Then something happened, Maybe I removed name and added it again that's what made it work, Not sure.
any hard evidence? show some transfer rates compares to ics.
maybe signal strength is not displayed correctly in jb?
bcos i dont notice any speed decrease on wifi since ics

This is a feature of JB that was added to prevent connection intermittently dropping due to a weak WiFi signal.
If you want the old behaviour go to WiFi settings, options -> advanced and untick "avoid poor connections"

Is really the signal weaker, or it is only a matter of scale?
