Data doesn't work after changing to 2g or 3g - LG Optimus 2x

Does anyone know a solution for this annoying problem? After switching 2G to 3G or vica versa the internet will not work, shows 2G or 3G connectivity but the upload and download arrows never come up and there's no connection.
thanks

restart?
maybe that's help.
also, wipe cache from recovery.

I restart my phone 5-6 times a day, I install new kernels often so cache clearing doesn't appear to help.. im thinking its some kernel related bug but it happens on Neoblaze and Horsepower.

I'm having the same problem. After flashing HP RC 4 (or so) kernel, mobile connection just doesn't work at all, either 2g or 3g. I tried flashing cm7 (from Topo) to see if the problem is with the ROM, but it still doesn't work.
Since I mostly use wifi, I didn't notice when it stopped working, plus I usually disable mobile data. Haven't tried flashing another kernel though :/

[Q] MIUI no data connection

Hi,
I got a Milestone A853. Vulnerable Bootloader 90.87 and MIUI 1.7.1
When I installed MIUI i got a Data Connection (e - hsda) without any problem.
Even after wifi.
After some hours of use i cant get a data connection.
odd at this is that i changed nothing.
I just got into Open recovery mode and changed the keyboard layout. But yesterday i didnt recognise or made any changes.
so i dont want to wipe everything when i want to use the data connection.
I turned monitoring of data connection to off in the "Monitor" of miui
What to do to get my connection back?
I am looking forward to your answers.

Have you tried reflashing your baseband in OR? You can try wiping both caches and flashing the baseband again, see how that goes.

Hi,
thanks for the answer.
i am living in germany. so i opened OR an flashed "germany.zip" in baseband menu. it isnt working...
In monitor there is an option to shut down your data connection when you reach a particular level. Have you checked if you have exceeded your limit. See if you have checked turn off automatically.

try to clear cache and dalvik cache in xrecovery
Wifi dying after a period of time.
I have a similar issue with my X8.
The Wifi works fine for a while (longest so far has been about a month) and then it just stops working. It picks up no signal what so ever from anywhere (my home router, which is about a metre away, is currently "Not in Range").
I've tried multiple versions of Android 2.2 from XDA and am now running 2.3 from the following link: http://forum.xda-developers.com/showthread.php?t=1109563
The only way i've found to bring back the Wifi is to do a FULL restore (system, data, cache, everything). I've done abt 6 restores since i started using custom ROM's about 4 months back and am in the situation where i have to do another one now. This is getting EXTREMELY irritating and I would very much appreciate it if someone could give me a solution for this.
Also, I have a lot of trouble connecting to the internet at my uni. This has been an issue from the very beginning on the X8, even before using custom ROMs. It connects the first time and then refuses to connect a second time. To connect again i have to forget the connection and start again. I don't know to describe the Wifi type but the instructions for connecting to it are in the following link http://uqconnect.net/helpdesk/wireless/eduroam/android/.
Thanks in advance
have this problem too. when i was on GDXv007 was fine then when it update to v008 i cant connect to wifi anymore.just keeps saying "obtaining ip addrees" then reboots. HEEEEEEEEEEEEEEEEEEEELLLLLLLLLLLLLLLLLLLLLLLLLLLLLLPPPPPPPPPPPPPPPPPPPPP!

Yes, this was helpful... But I have to Delete the networks I remembered, always?

[Q] Revert to Mobile Data

Hi - I'm running ARHD 21.0 on my HTC One, and sometimes, when I disconnect from a wifi network, or am out of range, my phone does not revert back to mobile data, until I restart it.
Do you have the mobile data option enabled? and if the mobile data coverage in the locations you have this issue in?
If so is it supported in the ROM you are using?
Then if it is a clean install may be the way forward

Thanks - I have got the mobile data option enabled everywhere I'm having this issue - and it is intermittent.
I'm not sure what you mean by 'is it supported in the ROM?
I may have to resort to a clean install, but am trying to avoid one.
If it is an intermittent issue then it is ROM supported, it may be coverage related, on Phones good signal strength does not always mean that there is available bandwidth on the local cell tower
I would plump for a reset or a Clean re install of the ROM

I think maybe a clean reinstall is going to be the best move - because, I find that if, without changing location at all, I restart my phone (or turn airplane mode on/off) then, the phone finds the mobile data, and usually its H+ with full bars.
Thanks so much for your help though.

[Q] CyanogenMod 2G/3G problem.

Hi, I am currently using Mackay's ROM which is CM 10.1 based. Sometimes when I turned on 2G data, it won't connect at all. When I tried switching to 3G, it stays at 2G and nothing happens. When I switched to airplane mode, the data switched to 3G but the signal bar stays full bar on my drop-down menu and there is no signal,aeroplane icons on the top right corner of the phone. The problem also occurs the other way round when i switch from 3G to 2G. The problem is only solved when i reboot my phone, however after another few minutes or so, I have to reboot again for data connection. Does anyone have a permanent solution for this? As it is frustrating to keep rebooting. And i tried changing APNs. The default APN for me is MiWorld WAP (GPRS). However, the default APN does not really connects. It's like a Laptop having a 'Limited Connection' WiFi. So I can only switch between the other 2 APN with is M1 and Sunsuft Internet, which the problem still occurs. Thanks to anyone who replies.
Have a nice day!
Already tried flashing a newer baseband?
Sent from my LG-P760 using xda app-developers app
Yes, sometimes this happens to me too...but it always did with every CM10/CM10.1-based roms.
I tried many basebands (v20, v28, v30), but it always happens. To me, about twice a week.
I always thought this could be related with the fact that we don't have a baseband made for jelly bean, and so I gave up on this issue.
When it happens, I simply reboot my phone.
And I avoid to use airplane mode, because usually after disabling it (if I left it enabled for more than a few minutes) I can't get network coverage until I reboot.

Thanks for the reply. I will try flashing newer baseband.
//Edit 1 What is the recommended baseband in Singapore? I tested V30B Euro OPEN, but doesn't seem to solve it.
//Edit 2 I read on other threads which says choose the baseband from your region, and i went to download a V30C Singapore version of the firmware and extracted and flashed the baseband. It seems to be working well.

Reboot is always required to use internet.

This is very inconvenient. If I disconnect from WiFi or LTE, then reconnect, apps do not detect the netwoork unless I reboot first. Has anyone experienced this problem or have a solution?

Have you tried changing the Wi-Fi band on your router ?

Never thought of doing that. I don't think that would be a complete solution though, because on LTE the issue still exists; it is not just a problem on WiFi.
Are you using some extreme power saving options/solutions/aps etc etc ?
Change wifi to 4G and try again.

Last nite I installed the OTA update of android 9. Since then the problems have been non existant. I will continue to update this post, and try all the tips I have been offered, if the problem returns.
I found the source of the problem. The VPN I use was preventing the apps from accessing the Internet.
