I also posted this in the Networking Forum, I am not sure which one is correct.

My brother's laptop computer (Dell D600) started acting up, blue screen and could not connect to the internet. I went in and ran a chkdsk and I tried to get on the internet and could not. I called my ISP and we were able to get a wired connection (plugged ethernet cable in back of computer) but could not get a wireless connection. The ISP is telling me that it may be a problem with the wireless router and that may be the case, but other computer are working wirelessly, but I think it may be a configuration problem and I want to try that before going to the store and getting another router, when I brought this up they saw the point I was making and told me that they will have to charge me to help me troubleshoot the configuration.

This has happened before and I don't remember the specific steps but I remember some of the steps like I cleared out the cache and there may have been other steps that I forgot. Then I brought up Explorer and when the error page came up there was a trouble shooting button, but for some reason an error page comes up but not the one with the trouble shooting button.

Can someone assist me? Thanks.

Yap. This has worked for me before as well. You may also try the trial period of Network Magic. Did not your router come with a disk whereby you can add a device when run on a particular machine? Sometimes temporarily disabling the "lock" on the router (also a tool on the router setup disk) while trying to add a device can be helpful.

I tried unplugging the modem and router and restarting the computer at least three times and that did not work.

I did not get a CD for the router. I downloaded Comcast's Desktop Doctor and that is not working.

Also I think that there may have been a step where I put an IP address in the URL line, 192.168.x.x (?) but I am not 100% sure if I am remembering that correctly.

Hello and welcome..
For the connection try these...

Please click Start > Run, type inetcpl.cpl in the runbox and press enter.
Click the Connections tab and click the LAN settings option.
Verify if "Use a proxy..." is checked, if so, UNcheck it and click OK/OK to exit.
Now check if the internet is working again.


Go to Start ... Run and type in cmd
A dos Window will appear.
Type in the dos window: netsh winsock reset
Click on the enter key.

Reboot your system to complete the process.

If needed : type these one line at a time, press enter after each line. See if it works after each.

netsh interface ipv4 reset
netsh interface ipv6 reset
ipconfig /flushdns

Have you tried uninstalling the wireless driver and then rebooting?
Or sometimes if you update the driver that may help.
