I recently upgraded my setup to a new WRT54GS Linksys wireless router, with one machine wired to it. This machine works fine.
Another machine, upstairs, is using the USB Wireless G adapter, Linksys WUSB54G. This machine previously had a Wireless 802.11b USB adapter (Linksys), mated with a BEFW11S4 v2 wireless router (now decomissioned). This machine runs Windows 2000 (with SP4).
After disconnecting the old adapter, and uninstalling it's software/drivers, I ran the setup for the new adapter.
It all installed fine, and when I connected the Wireless G adapter, it found and linked up with the router. It was given a proper IP and all that, and could access the internet.
Windows Auto Update detected there were some new updates, and offered to retrieve them. I let it do so, and left the machine to download the updates.
When I returned about an hour later, the machine was at the "Updates installed, Restart now?" screen.
I clicked no, and intended to check something over the internet first. Unfortunately, I could not bring up any sites. Checking the Linksys tray applet, it indicated the connection with the router was ok, but the internet could not be found.
I let the machine do it's restart, when it came back up it said the same thing. Running an IPconfig showed the machine did not see the DHCP info from the router, and had assigned itself the defunct IP in the 169.x.x.x range.
So in short, the machine can associate with the router ok, but cannot obtain any DHCP config from the router. The router's settings all appear correct. DHCP is enabled on the router.
I'm not quite sure how to proceed. Any suggestions would be most helpful.
