I'm having an odd problem with my wireless network. Here is the background information:

Server (Windows Server 2008) 1 to 10 end user machines connecting to the network Layer 3 Access Point (Asus WL-330 gE) connected to ethernet of Server and all machines connect to the network via the AP

The end user machines get a connection to the server with no problems initially. But then connections are randomly lost throughout the day to the server/network. The wireless NICs of the machines still see the wireless network but are unable to connect to it. Then after some time the connection is regained automatically.

I initially thought there was a problem with this particular AP, but then I took the same make/model AP out of storage and still ran into the problem.

Any ideas what could be causing this??? Very confusing that the wireless nics on the end user machines can still see the network but not connect, and that the connections are randomly lost/gained.

Thanks in advance!
