I have no problems with wifi in general, but:
1) Turn on wifi.
2) Recieve/send mail without problems
3) wait 5 minutes
4) Recieve/send mail: Does not work. "No route to host" or "Network unreachable"
5) Browsing/facebook etc. works fine
6) turn off/on wifi: Mail works again (for a short time)
I have tried with some other mail programs (K-9), but it has the same problem. No problems recieving mail over 3G (even though I do not use that a lot). It also happens with two different wifi networks (one secured by WPA2, one by WPA).
I have no idea what might cause this. Any ideas?
