This is possibly due to an issue at the network level, for instance with
the router. Please see if when you're connected and the traffic no
longer passes, what goes in and out of each interface eth0 and wlan0:

sudo tcpdump -i wlan0
sudo tcpdump -i eth0

I think you'll be able to see traffic going out of eth0, and back in
through wlan0 which would be incorrect.

Title:
  Internet stops working when connected through wifi

Status in “network-manager” package in Ubuntu:
  Incomplete

Bug description:
  Internet stops working when connected to wifi. Requires me to try to
  reconnect, but it keeps trying to connect to wifi and never connects.
  Then it asks for password, but does not connect even after submitting
  the right password. Resetting the modem allows one to re-connect but
  it again stops after some time. Wifi worked correctly in natty but
  problem occurs since upgrade to oneric.  Similar problem occured in
  natty when i started using the backports for wifi. Reverting the
  backports fixed the issue in natty, but no solution seems possible in
  oneric.
