    I have a:
    Gateway MX6124 laptop, XP - S2.
    Modem=Soft Data Modem w/Smart CP
    Adapter = 1394 Net Adapter
    Adapter = Broadcom 802,11g Network Adapter
    Adapter = Marvell Yukon 88E8036 PCI-E Fast Ethernet Controller

    Ipconfig reports it has 0 IP, 0 Subnet. Autoconfig is on.

    1) It connects w/no problem to my home wireless, running a router.wireless modem supplied by Qwest. (I'm not there right now to look it up)

    2) At work, they installed a wireless net running a D-Link something or other(???). I got onto it w/not much trouble when the tech installing it was here. It is protected: They installed the secret keycode.

    In second week of operation, all of a sudden I can't get onto the wireless.

    If I click on the network icon,
    General tab = Status - Invalid IP address
    Support tab = IP is invalid.

    If I press |Repair| button, it searches forever trying to connect...
    Passes on "Connecting to the wireless network."
    Hangs up forever on "Renewing your IP address".

    Can anyone help on next steps? I am afraid to change anything on my own, if that means I may cut myself off from the home wireless!

    Many thanks,

    If you're still able to connect at home then this is probably an encryption problem. They may have changed the key, or sometimes the router and adapter get "out of sync" and one solution then is to delete the profile and connect again, re-entering the key. If you don't know the key, obviously you can't do this on your own.

    One thing you can try is a System Restore to when it was working.

    The work network is using dynamic addressing, right? The reason I ask is that some companies use manually assigned addresses, and I'm just trying to guard against the chance that you changed your computer back to dynamic to get connected at home.
