me/2k Wireless issues

Good Morning! I have a network with 4 ME workstations and
one 98SE workstation. They are all connected to a
Win2kSvr using a wireless connection. The Access point in
use is a Netgear FVM318 Prosafe VPN Firewall/Router. The
Wireless nics in place are D-Link DWL520+ pci cards. The
network is set up using static IPs, no WEP, Trusting PCs
based on MAC, and Channel 11. There ia another wireless
network in the area on channel 1.

Problem: My ME users will drop their network connection
at least one time a day. When the users attempt to use
the mapped drives, they are not there. They show a zero
size in My computer. They can either disconnect and
reconnect the drives or log off and back on.

Any suggestions on this matter would be great!

TIA!!
