Ok, so you have to break this down. Troubleshooting Internet connectivity issues is a methodical-logical process. Since your other computer connects, it is "fairly" safe to say that the problem isn't at the ISP end, but at your end. So what you need to do is remove anything that is more than likely the issue. Do you connect by a wireless connection to your router? If so, what you need to do is unplug the power to the modem and connect the Toshiba laptop direct to the modem with an ethernet cord, bypassing the router entirely. Plug the modem back in and when it settles down, restart the laptop. When its back up, see if you can connect. If you can, its the wireless card in the Toshiba, or the wireless part of the router. If you can't connect with a direct connection to the modem, it may be a software issue as both network cards (wireless and wired) going at the same time is unlikely. Type "run" in the "search" area (just above the start button) and then after you hit "enter" type in "cmd". In the command prompt type in "ipconfig -all" and then hit enter. See if you are getting an IP address, subnet mask, default gateway and a whole pile of other stuff. If you get an IP, as long as it's NOT a 169.258.*.* you are getting a valid IP. Then type in "ping www.yahoo.com" and see if you get any replies. If you do, then you are connected, but if you can't bring up a web page, could be the browser (unlikely), or you may be using a firewall (seems that my Toshiba came with Norton in the trial software, not sure because I got rid of all that junk after I made restore disks). My sincere apologies if you have already gone through this. If after all that it still does nothing, smash it with a hammer, just kidding. Then I would say that it is a software problem that would require more screwing with. Colin
