You guys help with internet problems in here?
For the past few weeks I've been trying to solve internet problems that have been affecting just one of my computers. I think this originally started when I was forced to reset my router to factory default. No other system on the network seems to have been affected.
The current problem with my computer is that sometimes the internet connection will slow down by a lot for a few minutes. Much of the time it's normal speed, for for periods of a few minutes it will slow down to essentially nothing, but won't actually go out completely. When I try to load web pages under these conditions, my browser (all of them) just sits there loading nothing forever, but won't actually give me a "connection lost" screen. Also, it might only be me, but the connection drops seem to get much worse late at night. I've tried just about every solution I can think of and can't even figure out exactly what the problem is.
The computer is a desktop on wireless. I don't think can move it to a place where there's a wired connection.

What I've Tried So Far:
Reinstalling the latest wireless drivers didn't work.
I've rebooted everything I can possibly reboot.
I've done several security scans with Microsoft Security Essentials and Malwarebytes that turned up nothing.
I've reset the router several times.
I've gone between static and dynamic IP addresses with no change.
I've cleaned up all cache and temp files with CCleaner which changed nothing.
Changing the router's channel from 6 to 11 had no effect.
Windows diagnosis keeps saying nothing's wrong.
Forgetting and reacquiring my wireless network also doesn't work.
Clearing some registries in the Command Prompt also didn't work.
Disable SPI Firewall - Didn't work
Disable 108Mbps Features - Didn't work
Change NAT type to "open" - Didn't work
The same problem occurs in Safe Mode as well.
If I recall correctly something similar happened to my last wireless card before I decided to replace it. After I was forced to restore my router to factory defaults the connection on this computer would get slower in a similar way until it went out indefinitely. It could still detect wireless networks with excellent signal strength, but wouldn't connect, and I could never figure out why. It connected perfectly in Safe Mode and would also connect perfectly if I disabled all security in my router. Eventually I just replaced it with my current wireless card which worked fine for a few weeks, but is now experiencing slowdown which may or may not be related.
