More diagnostics is needed to make sensible suggestions.

A couple of things to look at next time you have a network outage:

* check the logs - mainly : /var/log/kern.log and
  /var/log/daemon.log. There might be interesting stuff in
  /var/log/daemon.log too. Messages with a timestamp immediately you
  lose the network connection may give clues to what is going on.

* Do you lose association with the access point?  ("iwconfig wlan0"
  and studying /var/log/kern.log for wlan0-related messages will give
  the answer to this)

* Is the network interface still up? ("ifconfig wlan0") Has it got the
  "right" IP address?  /var/log/daemon.log will show dhcp-related events
  here...

* Can you reach the access point with ping?

Hope this helps
