It's work to get 4g to turn on. Turn Sync, GPS, Bluetooth all off, then turn mobile data off. Turn mobile data on then switch to CMDA / EvDo, after getting solid 3G, switch to CMDA + LTE/EvDo, it should show up
I just tried the CM7 beta today, and had the same problem. After the phone goes to sleep, and upon wakeup, I have to go through the 3G to 4G routine to get 4G back on. Also I cannot get the GPS to work. Going back to BAMF 1.8 till the official release comes out.

THANK YOU! This got my 4G working without a hitch! I still do not have GPS working...it finds me but Navigation just says "Searching for GPS".

[Q]No data connection.

Im having troubles with my data connection. Basically, there isn't any data connection at all. Im sure that i have the correct APN. I can see the "E" (yes, its supposed to be E, its EDGE) next to the signal bars, but the upload/download arrows won't turn on. Its like its not even trying to connect. I can use WiFi fine.
I live outside US, in the Dominican Republic to be exact. Im using WetDream 1.4.4. Any solutions? Thanks!
Update: I tried with another SIM card with data enabled from another carrier, and the Atrix was able to connect to the data service fine, and i could access to the internet, but still no luck with my SIM. :\
BUMP =D
Try flashing a different kernel. I had the same problem and flashed faux's 1.3GHz unified kernel and now everything is working as it should

I called in for the exact same problem
The problem that was I did not have data on, and I had Data roaming on. So go to Settings > Battery and Data, and turn data on

WiFi connection slow down

Idk if it was the radio update or what, but recently, my WiFi connection had been reallyyyyy slow or just not connecting at all, and I've tried on a couple networks, so its not just mine, does anyone know why this is happening?

Have you checked your wifi settings to make sure that you have 2.4 checked instead of auto?. Also is your wifi set to never time out.? Also when was the last time you upgraded your routers firmware ?

3g stopped working

This is a weird to me. Currently using CM10 and using the network selector to change to roaming when at work (via Automatic selection). Yesterday, when I changed back to home network, my 3g signal wouldn't come back.
I've tried toggling airplane mode, wiped cache, but I really am at a loss as to how to get my signal back. Looking at the Phone info, it appears that I do have a sort of signal. If love if someone could help me out.

[Q] 3g stoped working, ideas?

Hi all,
I went on vacations, had my phone on airplane mode most of the time. When I came back I turned airplane mode off and now I can only connect to 2g antennas, if I select 3G only I don't get any signal.
When I try to manually search for network operators I get a "Connection unavailable" message
Any idea of what might be going on/how to fix it?

I flashed cyanogenmod to see if it was the radio driver but that didn't help
Check your apn settings maybe

When I select 3g only I can't even configure apns, I don't even get cellular signal.
Don't select 3G only. Use automatic.
Also if you have subscribed to a 3G plan, keep your data connection ON and try a restart.
Even face this often as i travel between two distant places once in a month. First time i did a factory reset. But second time onwards this helped.
