On my completely stock xoom, running the latest build, the wifi stops working after a time (not *sure* how long, but let's say an hour or two). After the wifi has stopped, the tablet will not locate any network (AP) nor will it detect them on the wifi analizer app, with shows all the networks in range and their channels and strengths. The app shows no network activity, which I know to be incorrect. However, after I reboot, all is well... until it fails again. When 8t fails, also, turni g the wifi off and back on again does not fix the wifi (that being a solution I found on other tablets running ICS... any ideas what this can be? Thanks in advance!
