My wife has an x201 tablet computer with Windows 7 and she has been experiencing intermediate wireless problems.
Everything starts out fine. We have a Tenda wireless N router configured with DHCP. The computer works perfectly fine when connected by ethernet cable and starts out fine on wifi, but after anywhere from 5 to 30 minutes or so, the browser no longer responds to any queries. Rebooting the computer or staying connected to the ethernet works, but that's not a good situation when trying to sit on the sofa or working on something important.
We've had the Lenovo support on the phone numerous times with a variety of different responses from "there's nothing wrong" to "you are missing a driver" but never is there a working solution. Lenovo even reinstalled Windows with the same problem recurring.
I'm not able to recreate the wifi problem at work so thinking that this could be a Tenda router specific issue, but wondering if anyone has an idea. Thanks.
