Wireless network adapter is unable to hold a signal

A couple days ago, I began having serious issues with my network adapter. It is unable to maintain a signal to the internet. When I say "maintain" I mean that it cuts in and out a lot. What it will do is, it will lose a internet signal, meaning, it is connected to the router but says "No internet access" and then it will do 1 of 2 things at that point, it will either completely disconnect to the router and will be "unable to connect" to it again, or it will gain internet access again for a few seconds and repeat the whole process. I can confirm that this is the computer having the connectivity issue and not the router because I can use other computers/devices and connect to the internet just fine. I have tried to resolve this issue on my own and researched it online on another device and I came up with no working solutions on my issue.

What I have tried:
-Resetting the Winsock
-Preforming system maintenance
-Attempting to do a disk check
-Using the Troubleshooter
-Updating the network drivers
-Doing a hardware test during boot up
-Disabling driver shutdown to conserve energy

A few things to note:
-Device Manager detects NO ISSUES with the driver(s)
-The troubleshooter says "a wire may be loose or broken"
-I don't have any windows discs
-Anti-Malware bytes doesn't detect anything excluding some registry errors (full scan)
-Microsoft Security Essentials doesn't detect anything wrong
-When I try to connect to the wifi settings page that you should be able to access even without internet access, it fails to connect.
-Adapter is able to find networks in range

If you need additional information, check my specs. I put most of em down when I signed up.

So does anyone have any solutions? Help would be MUCH appreciated.

I think the first thing I would try is another net adapter. For the purpose of troubleshooting, a USB wireless adapter is perfect. You would have to disable your current card. (You didn't post your net card specs, so I'm generalizing.)
If a friend has one or you can scavenge one from another sys, for a minute, that's cool. Load the appropriate drivers, disable your current card, check for connectivity and range, set Win7 to connect using the new card and post your results.

Good advice above trying a USB. Is your computer a desktop or a laptop? A friend of mine had similar issues which he put up with and then just decided to use a cable instead for a whole year. One quick look inside his laptop and I found the antenna connection was loose to his wifi card. Popped it back on, good as new.

I should know better than to reply to someone needing help who never returns to the site...
