I`m using MIUI rom from here on my phone. There is often some unknown problem with 3G/Edge connectivity when i disconnect it from Wifi. Nothing can help even changing between 2G/3G modes to force Cell reconnect. The only solution that can help is to reboot the phone, but WHY? If there is some patch/fix/anything to get rid of this problem?
Thanks a lot.
Please post in the correct section.

hi people
i'm noticing a problem with my data/edge/3g connection.
it simply stops working at times .. it just shows data being sent but no data received and my internet doesnt work.
This becomes fine after a reboot but again has a problem after a few hours
Is anyone else facing this problem too with Data connectivity ?
Yes, same problem with my german arc.
I am not facing any problem with data connectivity
same problems here, I found that stopping the WIFI and re enabling it is enough to get it back on track but its still a serious issue.
I don't like finding out I am missing e-mails an hour too late.
I only found it happens when I switch from 2G to 3G with data on.
So my work around is to turn data off first before switching between 2G <-> 3G. After that, turn back the data on.
This only happens to me on WIFI, on 3g everything is fine.
I am thinking about flashing the UK build to see if it helps.
I used to have the same problem with my x10. Data just stopped working randomly. I used to have a widget to turn 3g on/off and when the data stopped working, so did the widget. Was strange, and only a reboot solved it.
I have wifi problems,it sleeps after a while,no sleep is selectet.

i have wifi problem, at first it disconnects by itself and now much worse, my arc could not even identify or scan my wifi at home. Anyone also have this issue? or anyone know what to do.

same here. wifi works fine. til awhile later (evactly how long i didn't notice. will keep track)
After which no matter how i turn off & on wifi, forget the network & re-enter p/w. even off & on my phone. wifi status "connecting.... disconnected....connecting.... disconnected." will drains off a lot of battery if go unnotice.
i found a cumbersome work around... off the arc wifi & reboot modem/router. then can "obtaining ip address". but thing is, all other devices works fine.
so is it arc's fault? since all others can connect to wifi except arc
or
router's fault? i wasn't doing / changing setting on the arc. just reboot router. but wouldn't it be silly to do this everytime i use wifi on the arc?
so still no fix? sometimes it happens to me a few times during an hour...
Guys maybe this will help you out..
Go to wifi settings, press menu button->select advanced->under wifi sleep policy, set as never sleep
If not set the wifi shuts down to save battery.
And wifi is given more priority over 3g or 2g connectivity, so if you have wifi on you may not have proper connectivity to 2g or 3g
Turn on/off airplane mode, if you can't get a data connection. In a german forum some guys discussed about issues with multi-sim-cards, but I guess it is software related.

i changed my number and sim a couple of days back. with the same provider. my arc after being out of signal cant reconnect to the data network. the phone calls work fine. but the data is giving me problems. im still confused as to why this is happening. whenever i activate and deactivate the airplane mode, data connection comes back alive. could it be a problem with my sim or the phone radio?
edit: oh and i also reflashed my phone via sony ericsson update service, the problems still there.

Same problem here. This is really frustrating.
I dialed *#*#4636#*#* then phone info and pressed menu. Then I selected enable data connection (was disabled previously). The data didnt enable then. I went to settings>mobile network and enabled data from there too. Ever since, no disconnections. I dont know if this procedure or the fact that I tried to seat my sim properly worked, but u may try either. Let me know if this works....
Edit2: the above doesnt work.

I inserted my old fat sim and recreated the situation, the data automatically reconnected. The newer sim that's a microsim is causing the problem.

HI
I have a strange problem with my Arc s (the problem suddenly started this week).
when i turn it on the 3G works but after 2 minutes it show the H sign of 3G but no internet and also no calls. when i disable data i can call.
so i figure the 3G is working bad.. and cause to network in the device to fail..
its not rom problem.. i tried 5 different roms and the same (and the device worked great with he first rom before).
the store don't want to fix it because it say because i installed rom the warranty is expired..
can someone please guide me how to fix it ? can i order the 3g component and fix it? thank you
Hi,
Usually i have wifi enabled permanently, as i have coverage at home, university and t-mobile hotspots. But my nexus sometimes does not get a working data connection if i disable wifi or come back from flight mode. Icon shows reception and 3G/H/H+ but stays grey. I can't access any internet services like mail,http...
If i reboot the device, everything is fine.
Any ideas ?
Latest (-3days behind max) CM10 with stock kernel, XXLF1 baseband, tmobile germany
P.s.: tried to search with google, found nothing. Currently the nexus is my only internet-capable device, so i am sorry if repost...

Try toggling airplane mode?
Beamed from my Grouper.
Same issue here. Get random signal losses and afterwards no data until reboot. I've experienced this with other Roms as well. Toggling the airplane mode sometimes help for data recovering.
Try setting your minimum CPU above 500 Mhz...
How can that change the signal issues?
Maybe toggling wifi helps (sometimes)

I have exactly the same problem on galaxy s. The status bar shows mobile network connection, but the symbol stays grey, and connection is not there. Reboot is the only safe way to solve that. Sometimes toggling airplane mode helps, last time toggling wifi helped.
Changing APN seems to be helpful. Someone that looks good with the current provider.
almost same issue for me...
but there is some weird difference...
I have a GSM Galaxy Nexus latest radio, consistent RIL and latest CM10.
I lost data suddenly while browsing.
I can see blue signal with 3G, start browse and it change to H/H+. No problem until now but, when data returns to 3G, all further requests stay "pending" for a while (phone call is not working in this state!!!!). after a minute.... CRASH, all signal lost. Something like a reset.
even toggling data does not work... I simply have to wait that the phone decides to work again.
I'm from Italy, carrier is Vodafone. Someone with some hint?
thanks!

It's the correct APN, did autoconf OTA.

Because on earlier builds of some AOSP ROMs, the radio had a tendency to go to sleep and not wake up when the frequency dropped too low. The common fix at the time was to use a higher number for the minimum frequency...
Read you must...
I was looking up the answers to this same problem. When I'm staying still my internet is fine but when I'm driving down the road I lose signal. I did a google search for "cm10 losing data connection". This is a "normal problem" it is caused from changing between 3g and LTE 4g. I'm still looking up solutions to this problem.
Hello,
hard to describe my problem. Normally WiFi as well as 3G is turned on. At home the phone is using WiFi but when I leave home and do not have WiFi anymore it often does not automatically switch to 3G. I still have coverage indicated by the status bars but the H is missing. As a workaround to bring 3G back I can either switch between 3G and 2G or go into Airplane mode and back.
However, both solutions do not satisfy me. I want to understand why this does not happen automatically.
Thanks
Stock ROM? Rooted? Please answer these questions before posting a question...

I installed the unofficial CM9 and already downgraded from 3.35.20.10 radio to 3.35.19.25. Without success.
Might it be related to HTC Smartsync powersave issue, though HTC Wildfire Buzz should normally not be affected?
SmartSync is different.
Why didn't you have success when downgrading the radio?
No success in the sense that the problem still persists. Any ideas what I should try out?
I should maybe try out a different ROM. Maybe it's a problem with my operator.
Try a different ROM
I could resolve it by reducing the number of APNs to one.
Can someone help me fix my lg g3 signal problem. Experiencing no signal, since unable to connect to network operator but i have signal bars. Sometimes can connect manually to network when signal is strong but always automatically no signal. Is it hardware issue or software issue? I already tried other roms and downgraded to kitkat but still no to avail. Please help. Thanks.
Try to use Fulmics Rom 5.3, I have it without any problem on signal

Guys, unfortunately i have this same problem. My only option was just use the 3G signal (selecting on network settings). Its been passed 5 months and i still dont know how to fixed. I tried every ******* thing and the problem remains, at least choosing the 3g signal i can use my phone as a phone !!
obs: the problem started after updating to original MM.
I also have this issue, or similar.
Mine occurs when i connect to wifi whilst using 4g. If the 4g signal drops it wont automatically switch down to 3g. I have to do it manually , by changing to 2g/3g in network settings. auto/2g/3g/4g works fine whilst not connected to wifi though.
Mine seemed to start doing this when i first flashed MM or Fulmics.
I have tried flashing old radios, doing a complete unroot factory stock kds flash but nothing has fixed the issue.
Anyone any pointers or an explanation as to what could have possibly happened?
Cheers all
I had the same problem.
I flashed RPM and correct modem.
No signal drop anymore but no LTE.
Flashed modem again and RRom and it works perfect now!
I guess I should flashed the modem twice at the beginning.
