I tried some stuff I found about sleep policy. I obviously tried setting it to Never, I tried the Wi-Fi keep alive app, it doesn't seem to work.
When I let the phone lie for a few minutes and then wake it, the wifi icon is grey and i cannot connect to anything right away, I have to wait till it turns green. This also messes up my GTalk, plenty of times i found out someone wrote to me only by manually opening the Talk app and waiting for it to sync (there was the red unconnected line at the bottom).
How do I fix this?
I have Nexus S, if that helps. Thank you
