Laptop suddenly cannot detect wifi networks

So, here's the thing:

I had eveything going right on my Acer5315 last night, and today I boot 'er up and BOOM! Windows suddenly can't detect ANY wireless networks, including my own in the next room.  After some exhaustive research, I have checked the ping (ok), done a system restore (twice), and checked all drivers (ok).  I have no idea what to do next!  The router is a NetGear and was working perfectly when I checked.  Sitting on the hard line is a pain in the..well, you know.  Any other ideas?  Help!!

Do you know when this problem began?  Try a System Restore to a point in time BEFORE the problem began.  Here's the procedure:  Be sure to check the box to show more than 5 days of restore points.  If the first attempt fails, then try an earlier point or two.  NOTE: You will have to re-install any software and updates you installed between now and the restore point, but you can use Windows Update for the updates.  Use the recovery disk if the system prompt doesn’t work. The recovery disk works a bit different from the above procedures but if you follow the prompts from the System Restore menu option with the above information you should be able to restore with no problems.

You said you "checked" your drivers.  Did you just look in Device Manager and make sure they had no error symbols and  said they were working properly. You may be having troubles with your device drivers, firmware, and/or software despite what Device Manager says.  Go to Device Manager by going to start / search box and type device manager and enter and then double-click on the program icon that appears.  Check each device for a red x, yellow ! or white ?.  These identify devices with problems (probably drivers, but also conflicts or something else).  Click on each for further details and troubleshooting tips.  If you need to get drivers (and you should get any you have time to do - they may help in ways beyond just resolving this problem), do so from the computer vendor or device manufacturer (NOT from Microsoft Updates).  In fact, you should turn off automatic driver updates from Windows Update as follows: Proceed as follows to get the drivers:  Once you have the drivers, you can install them through Device Manager as follows:

I hope this helps.  If not, post back and we'll try some other options.

Good luck!
