So, right now I am using the Axura RC1 CE (I will update later), but I have had the problem described in the topic on various other ROMs using the JK3 modem.
It works fine for a few days (time is random, I have not been able to manually reproduce the issue), then randomly I lose all reception. Switching to flight mode fails, it gives no error, it just does nothing, in the notification bar it just says (searching). I have to reboot the phone to get the phone functioning again.
Anyone else experiencing this on ATTs network, or if there is a fix, I spent the last hour searching and going through the various threads to no avail (or I just suck at searching)..
Did you try the Axura thread?

I'm having the same issue but I've tried Assonance as well and still get the random no service. Tried different i9000 modems as well--anyone know if its safe to use a captivate modem??? I'm guessing no but just want to know if anyone has tried it without borking the phone.

I'm having this same issue as well, that's why I've tried to stay away from the UGJK3 modem, however, it's seems every custom ROM is starting to use it
As far as using a captivate modem with an i9000 ROM, I've tried that also, while it didn't totally brick my phone, I did get random FCs. I've read that is a dangerous path to go down.
I feel the same way. I might try the CogKernel and see if that helps...
Please, please, PLEASE do not post these types of things in Development.

+1 Lets keep this forum area clean .. its just for development stuff guys.
I have had the same issue with all I9000 modems, the only fix that has worked for me is to enter the service menu and force WCDMA 850 Band only. Also, questions should be posted in the question forum.
[this thread is pretty relevant to development - considering the rom chefs are using this modem in their releases and it has a potential major flaw. if the mods find it better to be in Q&A, then please move it - otherwise, i think the right eyes will see it here]
yes, yes and yes!
ive been posting about it in the perception thread, but no one (save for 1 user) chimed in with the same issue.
we both noticed that we both have an issue where we will bounce from 3G to H and back fairly often. this leads me to believe that it could be part of the problem.
i just odin'ed back to stock because my phone isnt receiving incoming calls now.
what i had planned to do was flash the latest perception but use a different modem... but it seems like the only sensible modem is the JK3 (although there is word on the street a new one just leaked?). so that idea is kind of out.
someone here said they were going to try cogkernel2, but i was on setirons and cogkernel2 and it happened with both. it seems to be a modem issue.
i wanted to lock the phone to use 3G only to see if that would help, but no one shared a way how... but reading this post it seems i can do it from the service menu - though i dont know exactly what to set/change to keep it only on 3G. (any help would be great).
so i believe im going to flash perception 8 and see if i can lock it into 3g mode and go from there. this is getting pretty tiring. im hoping if a new modem releases that will help, but i honestly am not sure i can wait since it is making the phone unusable.
below are my posts from the perception thread on the issue.

i see others have had issues with APN force closing. i do as well, but assuming that isnt a problem, i dont mind.
my issue is that after a certain period of time left asleep, my phone will completely fall off the network. changing flight and data mode dont work, nor help. a restart works. this has started a day or two ago, but was not an issue for the first week (give or take). if it is relevant, my network constantly swaps between H and 3G where i live.
i have not found a setting to force 3g (and disable hsdpa) as i figured it was the network hopping that was doing it. am i just missing that setting? anyone else with this issue? (again, i saw people with the apn force close but not complete loss of network unrelated to initial flash)
also, i think that each build should get its own thread. it is VERY difficult to find accurate information on the current build once a thread has 4 builds and 250 pages in it. even with search, it would still be a good idea.
thanks and thanks.

of note: going into wifi settings is also borked. it will eventually time out and FC. i also think that the times my phone has completely lost network and not reconnected have happened more often when charging. but that could be coincidence.

in relation to my post below yours, does locking the 850 band only force the phone to use only 3G, or is HSDPA/HSUPA still enabled but you found the 850 band to be more stable.
this is what my next attempt will be to get a solid platform going.
I've tried different modems other than jk3 and it doesn't fix the problem. Stinks that you've used Cogkernel2 and it doesn't help. I also tried the different band selection in service mode and it also hasn't help me (apparently this worked for some people). If you want to give it a shot do the following:
1. Dial *#0011#
2. menu button then soft back key
3. then phone control -> network control -> band selection
4. good luck!

ugh. that is disheartening. i will try the band lock, thanks.
can you confirm or deny that when you notice your phone goes completely out of service that it has been hopping between 3G and H? it would be interesting to see if we all have that issue as part of it.
also, fingers crossed for that supposed new modem.
/sigh
Yeah this really sucks because these roms are great with this one very big exception. I haven't noticed the hoping before I need to reboot. I have noticed that if I switch into airplane mode once I drop service I can't turn it off.
I had the same issues with Axura and Percetion. I found that switching my network control to WCDMA 1900 only pretty much fixed it. The only problem I had after was that any time I lost service naturally, ie, bad area, or shielded rooms, whenever I came back into a good service area I could never get a signal again. So I would have to reboot.
In the end, I'm back on Cog, 2.3b7 and no issues for about 14 hours now.

I'm using the non oc. I'm not gaming or doing anything too wild with my phone so non is just fine for me.

Hi,
Got a really annoying issue with my Nexus One that has been happening since the Froyo days, when I leave home to go to work I turn the Wi-Fi off on my phone to save battery. Sometimes I use the widget sometimes I go through the settings.
The problem is that the 3G doesn't alway's kick in, the only way for me to get 3G working is to turn my phone off and on which always works.
Any suggestions on why this is happening and how to resolve them?
I am running Stock Ginger Bread on my Nexus One on the the Vodafone network in the UK.
Try checking your signal strength: *#*#4636#*#*
You can try to enable 3G only and see if you can keep a signal.
My signal is sometimes intermittent due to topography. Stupid flat Ohio. Haha

Thanks, it won't be that though because once I turn the phone off then back on it's there. Also once I turn W-Fi off and 3G doesn't kick in, then it won't do untill I restart. Also another reason why I know this isn't the case is because even when I do this at work 3G doesn't kick in and there is a Vodafone 3G mast on the roof
never seen this problem before, but it sounds like something that might have to be fixed by doing a full wipe and reflashing your ROM. i know its drastic, so maybe do a nand backup first. then flash and see if the problem remains. if its still there, than just go right back to your backup and no harm and nothing lost. worth a shot.

I'm on a stock Nexus One unrooted so I shouldn't have to Root to fix an Android problem. Never Rooted before but considering it.
I got the exact same problem with Froyo and Gingerbread ROMs, can't remember if I had that issue with MIUI ROMs, but definitely with CyanogenMod ROMs.
Instead of rebooting the phone I suggest switching flight mode on/off it's faster than a full reboot
Haven't found any real solution yet and always thought I'm teh only one with that problem as I couldn't find any other person with that issue. Right now I'm testing different Radio/ROM combination and if that doesn't work I'll need to check if any app is causing the problem.
Any chance you are using Tasker?

I used to use Tasker but uninstalled it when I thought that it was causing this, it wasn't. Thanks for the tip about airplane mode, worked a treat.
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... :-(

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.
I have an issue where I lose mobile signal every few minutes. If I use Llama and check the "recent" tab I can see Cell: -1:-1:-1 every 10 mins or so and if I'm using the phone the signal will go to nothing, then within a few seconds go back up. Has anybody else seen this issue? I've done a factory reset and it didn't help. I'm waiting to hear back from Sony support, but they're been pretty useless for me in the past.

I encountered the same problem on my xperia l.
You could try taking the battery out the phone when it is switched on "hard reset" ,then take out the sim card and reboot, then switch off, put sim card back in and reboot, it may take a couple of minutes, it's worked for some, Me included
Another thing You could try is putting Your phone into GSM mode from settings but this means You need to keep changing modes when data roaming

Whilst we appreciate the sentiment please take a look at the forum your posting your advice in. The Xperia Z1 does not have a removable battery and the term 'switched on ''hard reset'' ' makes no sense unless you mean using the red button in place of a battery pull.
Not trying to be rude but its frustrating when your device drops signal and the best advice you get is regarding completely different hardware.
To Chrisduffer: Have you rooted your device/unlocked the bootloader or flashed another ROM? If so perhaps consider an alternative Kernel or a software update via the flashtool if its still using the stock kernel?
same problem. No root / no flash. Stock 4.3. Same issue even before update to 4.3.
Any idea what to do? My signal drops down every day like 5-6 times for about 20-30 seconds with no reason. I'm also not able to connect to 3G (at least phone is not showing 3g sign next to the signal strenght).
Hmm...this is interesting because actually I saw this up and down on mine too but I was able to call and receive calls anyway...so I newer bother if is an issue or not...but I losing the internet connection frequently so what's wrong?
Instresting...mine too...stock 4.2.2 rooted, Lb....but when my signal totally drops I am able to call or text!

Sounds almost like the modem driver is crashing and then restarting. Factory default is what I would try first, unless this is happening in places where you have weak signal or are in an enviroment which would cause weak signal (inside, thick walls, metal, etc.).

Hypothetically.
Had a few issues myself with the same stuff. Try another radio via flash tool. Just deselect everything else and just flash baseband, no wipe. Be careful when flashing stuff.

Yes, alternative radio driver should help, if it's not HW issue.
I will try to give the phone on a warranty check ... hopefully they will be able to tell me what's wrong ..
if not, I'll go your way = flashing different ROM with different radio.

thank you for the answer which rom could i install? now i have the rom for italy (IT) that i found here... but i had this problem also with the completely stock device so could it probably be an hardware issue?
You think you have signal issues?
Almost forgot, I had a phone come in once and it had the same issue, ended up only recognising the sim card every now and again, you could try another sim, or even send it back for repair which is what happened with the phone that was brought to me.

Any idea?
Should return the phone?
I sent the phone to the warranty, I have also the results of the tests and they are all passed... So I really don't know how to do... If I find a nexus 5 i'll try to change this xperia for that, I can't stay whiteout signal when my old iPhone 4s receive it very well

Your model is a d400, d400h or d400hn?. I have the same problem with the wifi
If going back to stock it is still the same after a factory reset (deletes all data, backup first) and with different routes then it's a hardware issue, no matter what model you have.

My problem was an update and restore the last version lol
