I am writing as I cannot find a solution in answered question.
I'm using and Android phone with 2.3.6 Gingerbread.
WiFi works on channel 11 (office), but does not work on channel 1 (home).
It (channel 1) connects but stops after 2-3 seconds.
I need to turn it on and off, and it works for 2-3 secs.
At the office, the WiFi works great.
Note that at channel 1 (home), other WiFi devices - PCs, Android phones - work fine.
Is it an Android version issue? I recently replaced touch pad under warranty. Afterwards, I had this issue.
