I've spent the last two or so weeks attempting to fix this problem. I'll explain it to the best of my ability. If you have any questions, I'll be happy to help you help me. My problem started about 10 days ago. Prior to this date, my service would drop, not predictably, but enough that I can remember it. Comcast has insisted there is no problem and no other computers on the network experienced this problem, so I assumed it was something local. I never made a real attempt to fix it, however, because it wasn't a big enough problem to bother me. A simple reboot would fix the problem. The error would occur most often when I was downloading media and running another program that was accessing the internet. The problem would still occur without both happening at the same time, however, so I assumed that it was a coincidence. 10 days ago, I was on the internet, browsing. I left for an hour and upon my return, found the internet was disconnected. I rebooted and, instead of connecting, an error came up. "Limited or no connectivity." After several more restarts, I was connected, but it dropped out again, with the same error. I connected looked my Wireless card up and it connected to the network. After several days, the wireless card came up with the same error. In addition, the error was still happening with the LAN connection and it would say the network cable is unplugged, when it is clearly plugged in. I would have assumed it was an error with the router, but three other laptops were able to connect to the network, as well as my desktop. The LAN cable refuses to connect at all and when it says it is connected, I still receive the "Limited or no connectivity error." The wireless card will connect, but often goes out with the same error. Right now, I'm using the Wireless card. Doing an IPConfig, the Wireless adapter is receiving all settings. The LAN connection doesn't see DHCP enabled, although it is. I'm unsure if this is an error or it doesn't see DHCP because it doesn't see the cable as connected (right now it is disabled and won't re-enable because it thinks the cable is unplugged). I've looked through many different webpages and attempted the fixes suggested, but nothing has helped. The cable is still functional and I changed no settings between the time that it worked and suddenly stopped working. I'm going to retest this by plugging the the cable directly into the modem and seeing what happens. I don't believe the NIC has gone bad, but in either case, I am unsure why this would affect the wireless card. I've disabled any firewalls, incase that was causing the issue, but it didn't help. Whenever the wireless card isn't working, I've noticed it still receives the signel strength as 100%. I've also noted that, whenever I get the "Limited or no connectivity error", the Wireless card nor the LAN connection is getting an IP from the router. This lead me to believe something was conflicting with my computer and the router, but I am confused as to why it would only affect the wireless card sometimes. I'm using an Inspiron 8500 running WinXP, using Comcast High Speed Internet with a Linksys router and Linksys Wireless G card. My onboard card is a Broadcom 440x 10/100 Integrated Controller. I have my computer docked in a docking station with the LAN connection going through the hub. Even connected directly into the computer, I still receive the "Limited or no connectivity error." I've contacted Comcast to see if they made any changes that may have only affected my computer. After I got through the bull**** of a recording asking me questions and got to a real person, I was told everything was "green across the board". When I questioned him further, he insisted it was the router, even if the router worked for me and is still working for the other computers and I changed no settings when the problem occured. (A logical reason is not the router in a case where it is working for other computers, nor does it explain why my computer dropped the connection prior to this while the other computers did not.) Any help you can offer is appriciated.
