I have a problem with WIFI in Android too. After wakeup from a longish (10-15 minutes long) sleep period my network connection becomes very slow. The loading of web pages hang and I cannot connect to the FTP server I created on the tablet from my PC, so local network access suffers too. The interesting thing is that WIFI is not completely dead. The signal indicator shows full strength and I can ping my router and the IP address of youtube.com. I don’t see anything special in the logs. After 2-3 minutes of suffering the connection becomes normal and everything loads with normal speed.|
The BIOS update in this thread didn’t help at all. It installed OK, but no change in the positive direction.
In windows WIFI looks to be OK, so it must be some kind of software/driver problem in Android. Somehow WIFI screws up after a few minutes of inactivity. Maybe it doesn’t come back from power save mode quickly enough, I am only guessing.
I am getting fed up with this, please do something about it.
