I have lost the ability to connect to the internet with my desktop (Dell XPS 420). I have a Netgear WNDA USB adapter but it cannot find any networks. It is not the router because I have a laptop, iphone and tablet that can all connect. At first I could see the network but it was "bumped" by this Virtual Network and then it would not be able to connect. I found online an article describing the same problem so I followed their recommendations. I removed the Netgear software and reinstalled it from the CD but now it will not even bring up the control module to connect/find the networks. What's even stranger is that the computer will not connect with an ethernet cable either. Help!

Try using System Restore to roll back Windows to a point in time when everything when your computer was functioning correctly. It allows you to undo system changes without affecting your personal files, such as e-mail, documents, or photos.

That's one of the first things I tried. It would not allow me to. Then I tried multiple times to reinstall the wireless software. Unfortunately, I did not realize it kept creating new restore points. I exceeded the storage capacity so my older restore points are gone. Kinda strange. When I go to system restore there is only a couple and I do not have the option to go longer than 5 days. As if it had been erased. I am stumped as to why I am unable to connect either wireless or with the ethernet cable. The errors I get when I use the diagnosis feature are:

Network Adapter "Intel® 82566dc..." is experiencing driver or hardware related issues (when I try the local connection) or

Network Adapter "RangeMax Dual Max Wireless N..." is experiencing driver or hardware related issues (when I try the wireless connection). Resetting the wireless network adapter does not help. 

The wireless adapter is a NetGear WNDA3100 USB adapter

I have also tried the following:

 

  • Booted up in safe mode with networking: cannot find any networks
  • ipconfig /release, ipconfig /renew, got the following error: "Windows IP configuration. No operation can be performed on Bluetooth Network Connection while it has media disconnected. An error occurred while releasing Interface Loopback Pseudo-Interface 1: System cannot find the file specified"
  • Went to Network connections and made sure that "Obtain an IP address automatically" and "Obtain DNS server address automatically" were checked.
  • Reset Winsock and reset TCP/IP.

Nothing works. It just cannot find any networks from the wireless or ethernet connections!!!

Under Network Adapters in Device Manager, right-click each one and select Uninstall. Reboot and on boot up, Windows should run through its "Found new hardware" routine and set them back up for you.

SpywareDoctor, first of all thanks for helping me with this problem. I followed your advice and unistalled the network adapters. I did not check the box to remove the drivers since you did not suggest that. It worked for the local connection, I again have internet access if connected to the router through an ethernet cable. Not a problem since they are close to each other. However, I am still not able to connect to the wireless. I tried reinstalling the software from the CD, checked for updates, reinstalled the driver, but when I go to Manage Wireless Networks it cannot find any. I'm not sure if it is a problem with the desktop or with the USB adapter or the software. Again, not as big of a deal now with the ethernet connection but I would like to know what the issue is in case I need to move the computer or router somewhere else in the house. Any suggestions would be greatly appreciated.

I'd try a different USB WiFi Adapter. If you don't have one, you can pick one up for 8 to 9 bucks, including shipping.
