Solved windows laptops won't connect to internet

October 18, 2011 at 17:06:08
Specs: Linux i686
There are currently 6 laptops in my household....4 windows (1 vista, 1 xp2002 pro, 2 windows 7) and 2 linux (both ubuntu). Night before last, without warning, all 6 stopped connecting through the wireless router. I took the router out of the mix, and now only the linux laptops can connect to the internet via ethernet cable. comcast support is useless...any ideas what could be happening here? Only 1 of the linux and 2 of the windows laptops were connected at the time this occurred.

From the sounds of it, your router may be broken.

Click on my name above in this response and read my “how-to” guide titled, “Troubleshooting Wireless Issues” and go through the steps listed there. The troubleshooting steps work for basic router issues.

I suspect the reason only one device is able to get internet connectivity when connected directly to the modem is that your ISP only allows one or two MAC addresses to connect to it. You would have to call them to verify that. If that is the case and you have to replace your router, you'll want to have them reset the MAC mapping on their end or, spoof the external MAC address of your broken router onto the replacement.

Did you shut all devices, then start the modem, router & laptops in that order?

Yes, even repeated that process and left the router out of the mix...same results: nothing can connect wirelessly, and only the linux machines can connect via ethernet.

update: i powered everything off again, disconnected the coax cable, waited a few mins, now ONE of the windows machines - the one running xp2002 pro - will connect via ethernet. Wireless remains 100% down, and until i see all of them connect via ethernet cable, i'm not going to mess with the wireless router.

Is that a Westell modem by any chance?

Uhh, if your attempting to connect all 6 computers DIRECTLY to the internet, that won't work; unless you have 6 public IP's of course.

Something happened to your router or modem

well i was only trying to connect one at a time via ethernet; that is what puzzled me so much....even that method did not work on all of the windows laptops, but after disconnecting the cable from modem and LEAVING it disconnected for 10 minutes, the xp and vista laptops also connected via ethernet. I don't know much about windows 7, but once i replaced the router all laptops were able to connect wirelessly...didn't have to contact my ip provider or spoof anything...just a straight swap.
