Wireless connection has disappeared
System: Alienware M17XR3 with DW1501 Wireless-N WLAN Half Mini Internal Wireless Card. Running Windows 7 Home Premium.
Wireless connection has worked fine for years. Yesterday, with no program changes, a red X appears over the network connection icon and it states: "Not connected. No connections are available". This while plugged in to charger with power profile set to performance.
It will connect to the internet via ethernet cable. Toggling wifi on/off with the media control button changes nothing. The network is available as two other computers connect to it without problems, one at 2.4GHz and one at 5GHz (dual band router).
Upgraded router firmware. Installed new wireless card driver. No effect. Wireless is activated in BIOS. Device manager says all devices operating without problems. Windows network troubleshooter can not identify the problem. Alien Autopsy finds no available network.
Uninstalled DW1501 and driver and reinstalled. No joy. Uninstalled again and tried to install a USB wireless card (Linksys AE1000). Linksys install CD could not install, says wireless control may not be Windows, which it requires... Downloaded Linksys driver for AE1000, installed thru Device Mgr, shows up working in device mgr but still no wireless connection.
It appears that neither my internal adapter nor a USB adapter can receive the wireless signal that is indeed present. Any suggestions? I have run out of ideas.

Questions:Were you attached on a public wifi connection?
Did you see a man dressed like a professional magician giggling around the area?
I suspect it is your wireless manager in the operating system not the driver. (windows)
In Linux, (long pause..... what?) change your file permissions to root read/write user read. Usually +644
+30m later
You may have to refresh your OS system files. Get your OS disk ready and type the command in the command line.
'sfc /scannow'
It replaces the damaged or altered system files.

No magician, and no public wifi connection, I am using a home network. In the past, this laptop would pick up not only my network, but those of some neighbors also. Now, it seems dead to any wifi network.
I ran sfc as you suggested, it found no missing or corrupted system files. I have also tried to run in safe mode with networking, but this does not work either. I have used system restore to restore to a known good point, still no joy.
The problem persists, and my frustration grows....

No. But after I posted here I noticed that neither of my smart TVs or bluray players could see my wifi either only my phones could see it. Telus agreed to send me a new router just to verify that it isn't the problem. Still waiting for it though.
