I have a MacBook 13" purchased in may 2008. I connect to an airport express.

The airport express is bridged to a linksys wrt54g running dd-wrt.

When I setup the airport express, the MacBook has no problem finding the network, but after a while (a week or so) the network disappears. Many other networks are available. My PC has no problems finding the network.

The airport express is setup running wpa/wpa2.

I have searched the www throughroughly but I have not found a solution. However, I have seen similar problems descibed.

Sometimes I can connect to the network if I restart the airport extreme and the MacBook

The macbook has the 10.5.8 update installed.

CAn any one help me?
