Ok I was trying to access my router because I have to change my NAT settings in order to play Xbox Live (because my router is upstairs and my Xbox is downstairs connected through my laptop). I have a Linksys WRT54G Wireless-G Router and I am using a Windows XP desktop, and Mozilla 3.5. Every time I try enterting my router's ip address 192.168.1.1. on Mozilla it just give a a black white page and the status bars says done, when I try in IE it's says "Internet Explorer cannot display this page". So I tried to to run ipconfig to see what was wrong and every time I try to run ipconfig, it flashes on the screen for a second and then disappears. I need some help please!
Also FYI, my router is not directly connected to my modem, my modem is connected to a Packet 8 VOIP box and that is connected to my router, but I was still able to access my router through 192.168.1.1 before in that same setup, until now.
