When I first installed the WRT54GS v.4 wireless router, everything worked fine. But I wanted to see if there were other PCs connecting, so I reinstalled the software thinking it had never been installed (and not realizing there is no way to view traffic). Long story short, I've finally got it to work again, but now I can no longer access the web-based administration page 192.168.1.1 - I get the message "401 Unauthorized Authorization required. " I can ping it just fine with no packet loss. I've pressed the reset button for the more-than-30-seconds to reset factory settings more than a dozen times. In addition, the WUSB54G v.4 Wireless-G USB Network Adapter now can no longer access the internet. But it can ping networks! When the SecureEsySetup button was clicked today in the Network Adapter admin page (on the secondary laptop) it hosed up the wireless connection on the primary laptop that is connected via its internal wireless card to the WRT54GS. So after reinstalling the WRT54GS, oddly, the LED has remained white. My primary wireless laptop is working now though. I am pretty much a newbie at this router stuff, so hope someone can provide step-by-step instructions. Most important is simply to get to the web based admin page. I'd like to upgrade the firmware on this router, among other things. I did search through old posts and can't find something similar with an answer. Thanks!
