Question Laptop wireless connection won't connect to router
I recently had Verizon high speed internet installed in my house. I connected a laptop to the router with an ethernet cable and everything works fine. I managed to connect with another laptop and another computer via wifi and they also work fine. I now want to disconnect the ethernet cable and allow the original laptop to be mobile around the house. When I first tried this everything worked fine. When I tried again (with the ethernet cable still connected) the wireless internet connection was recognized but would not allow me to connect. The message was something to the effect of "Windows is unable to connect to the selected network. The network may no longer be in range. Please refresh the list of available networks, and try to connect again." The network is certainly there and the router is right next to the laptop - fully in range. The same thing happens when I disconnect he ethernet cable. A few times the router didn't even show up in the list of wireless interner connections. I might have changed some setting someplace but I don't know which one.
I am stuck as to what the problem might be. If anyone can help it would be greatly appreciated!

With the laptop six to ten feet from the router ...

Please attach a screen shot of the Networks page (don't collapse the Radar, Connection or Signal History) of the Xirrus Wi-Fi Inspector. If you need help with that see TSG Posting a Screenshot. FWIW to take screen shots with Windows 7 or Vista I prefer to use the built-in Snipping Tool.

Also show ...

Open a (black) Command Prompt window:
Hold the Windows logo key and press r; in the Run box type cmd and click on OK.

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.

Using Windows XP
Thanks for replying. Sorry that I forgot to mention that I am using Windows XP. I'm not sure what the equivalent of the networks page is. But here is the IPConfig:

Equivalent? Xirrus works fine with XP; just attach a screen shot of its (default) output.

You have ICS enabled, so that is likely your problem. Disable it and try to connect.

Xirrus screenshots
Here are the Xirrus snapshots. I was having trouble installing it and opening it. I keep getting a fatal error and then the networks screen closes - so I made two snapshots. They are attached. Also - the ICS is not enabled!

I don't know what's wrong. It may be the wireless driver, or the adapter may be defective, or there may be something more serious wrong with the computer or OS.

Make sure you have the latest wireless driver from the laptop manufacturer's web site. If you already have the latest reinstall it anyhow in case the installed instance is defective.

Maybe this means something - I tried by right clicking on the wireless internet connection to repair the wireless connection and I get the following error message - "Windows could not finish repairing the problem because the following action could not be completed: TCP/Ip is not enabled for this connection".
But the TCP/IP is enabled!!

Never ran across that before. I would disable it; reboot; enable it again and see if that helps.
