Wireless Network Connectivity Issue

Hi,


I have 2 small wireless networks setup in 2 different locations and
seem to be experiencing the same misbehaviour of certain client
workstations on both of them.


One wireless network has a 3Com OfficeConnect 11g Access Point
(3CRW454G72) and a Win2k runing Dell Optiplex GX270 with a 3Com
OfficeConnect 11 a/b/g PCI Wireless Card (3CRDAG675).

The other wireless network has a 3Com OfficeConnect 11 a/b/g Access
Point (3CRWE454A72) and a Win2k running Dell Latitude C610 laptop with
a 3Com OfficeConnect 11 b/g PCMCIA Wireless Card (3CRWE154G72).

Each network has a Debian Linux server acting as a DHCP server and
providing other services.


On both networks, the clients mentioned above are sending but not
receiving packets. As a result, DHCP requests are being sent by both
clients, received by the DHCP server(s) (as proven by the logs on the
server(s)), but are not receiving the DHCP lease sent by the server.


I have upgraded the drivers on both clients and the firmware on the
access points to the newest versions avilable from 3com.com, and due
to various other circumstances, had to reinstall Win2k from scratch on
both clients. After reinstalling the O/S on both machines, the problem
still persisted.


Other clients, some using identical wireless NICs, others using
completely different manufacturer wireless NICs are all able to
connect to the wireless networks without any problems. However, these
two clients specifically are refusing to receive packets.


There are no firewall programs enabled on either client and both
machines are able to receive DHCP leases on their wired 10/100 NICs.


Has anyone encountered behaviour like this before or have any ideas
what is casuing it?


Thanks

yeah, you have to change the settings in debian or just get a real router
and let it be dhcp server only by itself on each network
