Centrino disconnect after 45 minutes - won't reconnect

I have a problem with my centrino connection on my Asus W5a. It seems to
connect OK to WAPs, both at home and away in hotels etc, but then disconnects
after about 45 mins. These are both WEP encrypted and unsecured networks.
Once disconnected it cannot be convinced to reconnect with rebooting - all
pretty much as described in KB828940. Often no network shows up in available
networks, even though I am sat next to the WAP!

The PC is new - with SP2 installed.
Help!!

Thanks for the reply - I have set the power management to not shut down -
will see if it makes any difference.
