Hey, I'm experiencing flakey WiFi with my rooted tbolt at home. After some period of inactivity, the WiFi connection just stops. Signal strength is still shown in the status bar so I don't find out there's an issue until a sync w/ exchange fails. Disable/enable WiFi fixes issue immediately. AP is stock firmware running wpa 2 psk, no MAC filtering or anything custom at all. Firmware is latest which is 4 years old. Where to start - tbolt radio? Or newer firmware eg. Tomato, Dd-wrt? Would rather not install a WiFi fixer app bc of battery implications. Thx!
