Hi all,

I'm facing a weird WiFi problem which seems to be different from the ones that have been discussed before and referenced in the FAQ.

Specifically, when I just turn the WiFi on, I can connect to the network (WPA2-TKIP secured), authenticate and browse Web sites etc. There are no problems with the proxy, unavailability of WAP2 in the drop-down box - within first minute or two after turning the WiFi on, everything works as expected.

Hovewer, the signal strength is unstable, and once the signal dies a couple of times, the 8525 freezes: the backlight instantly goes off even if the device is AC-powered, and the device stops responding to anything except Soft Reset.

It should also be mentioned that my WiFi is configured for best performance, not the battery saving mode.

I was suspecting it was a hardware problem, so I hooked up my 8525 to my notebook over WiFi at home, using WEP security. I was hoping that if it was for the broken WiFi hardware, I'd observe the same freezing effect. Still, the WiFi worked just normally. I must admit I didn't intentionally emulate the loss of signal (should test it as well), but with nominal signal strength there were no problems at all!

So does anyone have an idea what could be the reason of 8525 freezing after loosing the WiFi connection? I know there are issues when WiFi is left turned on in standby mode, but, as I've said, in my case the 8525 freezes even if it's on AC power and is being actively used. I've also noticed that sliding the 8525 to access the keyboard somehow increases the probability of freezing, especially when the device is on battery power.

My OS ROM is wm6premium.v2, perhaps there are known WiFi problems with this ROM? Also, the Phone is HardSPL'd and SIM/CID unlocked. Please help, as except for this weird WiFi problem, I'm totally satisfied with my 8525.
