This is a strange one - we have a Linux Redhat Server providing a file share to Windows XP Clients. All PC's are on static local IP's. We have added a Netgear Prosafe Wireless Access point using a static IP with no DHCP running to the network for Laptop users to use the network. Within a few minutes of the WAP being plugged in to the network the .csv files stored on mapped drive Linux server will no longer open and display a path as http://.... Unplug the access point and the problem goes away! Anyone any ideas what might be causing this as it only affects .csv files on the shared volume ?
