Wireless Network Connectivity Issue

Discussion in 'Computer Support' started by Conall O'Brien, Aug 25, 2004.

  1. 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
