My UMA has been working great the last four or 5 months, suddenly I come home yesterday and after being connected to UMA for a few minutes, my screen goes black and my phone reboots. It's done this during 2 calls as well. I have a tmobile WRT-54TM router, and I have not changed any setting nor installed any new applications. I took out my sim card and my 4gb card and rebooted my phone a few times now. So far today it worked fine at work but has rebooted four times this evening while connected to UMA at home. I turned of wifi for now in "manage connections" and it has not rebooted yet.

I've read a few posts here about rebooting 8320 and UMA but the cause seemed to be mimo or N routers, and I have just the stock tmobile linksys (latest firmware).

(edit: no bluetooth is not enabled)

Any ideas?

Did you try rebooting your router? Unplug it for 30 seconds and plug it back in.

also have you updated the software on your device recently?

Thanks for the suggestions. I have done no software updates for quite a while now. Latest firmware, and device software from tmobile.

I kept on rebooting today. I had tweaked with my router settings with wuggested settings from a different thread- but it has worked flawlessly for months.

The log in the 8320 (alt lg lg) says Radio Error: send packet and that is when the phone crashes.

John: I set my router back to factory defaults and I have not crashed yet. Lets see if it holds.

Thanks for the help..
