So you are saying that one computer does not work, correct?

Often wireless adapters need to have their firmware upgraded.  if you have never done this do so now.  visit the linksys website and check out the downloads.  Such an upgrade can fix a myriad of problems.

Have you downloaded winXP sp2 onto any boxes?  This has new firewall "improvements" - really they are, but it have have caused your network probs.

The standard fix for any MS windows networking issues is to uninstall all, and I mean all, network devices and protocols on the offending computer.  (this implies uninstalling yout normal cat5 NIC as well I am afraid)  Reboot and reinstall.  

Take care during reinstall that things are done in the order recommended by any documentation- especially with USB devices.  Also make sure that you only have TCP/IP protocol.  Also do your cat5 NIC first - get yourself connected!

Ahh..  Make sure that you do NOT have your CAT5 NIC connected at the same time as your USB NIC.  That could be a cause of conflict.  One or the other, not both.

have several pc's. Only having the problem on one.

went to linksys - no firmware for adapter wusb11.
disconnected the ethernet cable and uninstalled the connection.
did the same for wireless-wubs11.

installed wusb11 adapterwithout connecting as per instructions from linksys docs. successful.
connected adapter to usb port. win2k detected and installed. same message as above, "network cable disconnected".
using linksys network adapter software i did a site survey. it detected my Acess point. i click on connect, i entered the wep key and it connects to access point, excellent signal/link strength but linksys software says "connected to access point but internet cannot be found". network cable error goes away, but no internet access!

just to clarify.
i am not in front of the PC, but the ip address i get fron the ipconfig begins with '169.' and i forgot the rest.
i can get the exact address when i return home.

In some Windows OS versions the address 169.x.x.x is automatically configured when an IP cannot be found.

Is there an onboard network card?  If so has it been disabled in BIOS?

Are there any network devices showing in Device Manager?

If so, what is the Device Status on the "General Tab" in that device's property sheet.

its says "enabled", now.
when i first installed the device, the status was "network cable unplugged".
but using linksys network adapter software i did a site survey. it detected my Acess point. i click on connect, i entered the wep key and it connects to access point, excellent signal/link strength but linksys software says "connected to access point but internet cannot be found". network cable error goes away, but no internet access!

This adapter works on my laptop without any problems, even with my on board ethernet network card enabled!
Also have been using a usb mouse without a problem just to verify the port is OK!
