Ive had this Gateway (running Vista) for over a year and haven't had any problems using the wireless until tonight. The wireless ceased working suddenly tonight. However, it was/is working on my Mac laptop. After clicking "Diagnose why windows cannot find any additional networks", I was told the wireless capability wasn't activated. I clicked f2 and function several times. The wireless light is CLEARLY on. I did some digging around on the internet but haven't found any possible solutions. Apparently, ZoneAlarm has done this to a few computers in the past but I don't have that program on my computer. Any ideas?

Addendum: I restarted the router as well as the laptop itself numerous times.

My System


Hold the Windows key and press R, then type devmgmt.msc

Please respond to all the following steps.
  1. Under Network adapters, please tell me all the devices listed.
  2. Are there any devices under Network adapters that have a red x displayed?
  3. Also, are there any devices anywhere in the Device Manager display with yellow ? or ! displayed?

It would be best if you could post a screen shot of Device Manager with the Network adapters and Other devices sections expanded.

To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file. To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here.


Let's see this as well.


Hold the Windows key and press R, then type CMD then press Enter to open a command prompt:

In the command prompt window that opens, type type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

IPCONFIG /ALL

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

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

Download and run this Xirrus Wi-Fi Inspector, click the Networks link on the upper left and paste a screen shot of that screen here. Note that this application requires NET Framework to run. If you get an error about a missing function, download and install NET Framework. For machines with no Internet connection, download this NET Framework 3.5 Full Package on another machine and transfer it with removable media to the problem machine.
