If you can post the inSSIDer page then run a simple system file scan it may tell us more.

Run the following command in an elevated command prompt, might take a little while to check the system files. Let me know what the scan says.

Code:
sfc /scannow
Here's the inSSIDer report. The "thefamily" network is my network. The sfc /scannow command came back with no problems.

I'm really not seeing any problems here and the neighbors all have weak signals so overlap isn't a problem although changing the router to channel 1 may help.

Updating the drivers from the manufacture's site or visiting the Windows Update Center might be helpful.

Besides that Avast may create problems with network connections but it's hard to nail down the cause without uninstalling.

Starting in safe mode with networking may help nail down the problem to something installed on the system.

Safe Mode
I had the same idea with starting in safe mode so I did and the problem still exists there. I also have the latest unofficial drivers that have worked fine on all my other computers. I may be in the market for a repair or new laptop soon :/

Or just purchase a USB dongle for like 12 bucks from Amazon although I might try using the official Windows WHQL drivers first.

I would also uninstall Avast completely using the special uninstall tool before I threw in the towel.
