I just had to play with such over the last week.
Here's what I went through. But let me say that I have no cure for you! I can only share my last experience.
1. The setup failed horribly. The new 802.11g router wouldn't even connect to the internet.
2. Updated the 802.11g's FIRMWARE. Bingo, connected to the DSL account on the first try.
3. The WUSB11 wouldn't connect. Updated it's firmware and driver. All the settings in the router were redone and now it connects.
It died again...
4. Opened a command prompt and for this ole 98 box typed ...
IPCONFIG /RELEASE_ALL Shutdown, pulled the AC cord for a 20 count, put it back in and booted. It's online now.
Best of luck.
I am adding a laptop (windows xp home, toshiba a65-s126 with integrated athenos super g wireless card) to an existing home network. My router is a linksys BEFW11S4 (wireless-b) and I am on a cable modem connection. Currently I have two desktops (one linux, one winxp) with wired lan cards connected to the router, and both can connect to the internet with no problem. I have used a wireless laptop on the network before, so there are no hardware problems with the wireless feature on the router. I have tested configurations with WEP enabled and disabled, but have the same results. The laptop shows an excellent signal strength and finds my network ssid, but when I try to load a web page, the taskbar shows "resolving hostname...", but the page does not load. I cannot ping the router or the other computers from the laptop, but when I look at the wireless client MAC list in the router settings, the laptop's MAC and assigned ip (192.168.1.19) appear. Thanks in advance for helping out!
