Windows 7 Desktop wifi all of a sudden slow

Hello. I have been having trouble for the past WEEK figuring out why my wifi suddenly slammed on the breaks. Here is my problem in detail.

About a week ago, my wifi out of nowhere slowed down. I assumed it was an ISP issue at the time, but no other computer was facing wifi trouble. The problem persists to this day. My adapter antenna (a Rosewill RNX-180UBE) on my desktop claims to have an excellent signal, yet I keep getting drops in mbps below 25.

As for my download speeds, they have rarely peaked over 300 kilobytes/s, when it's common speed was around 1 megabytes/s. And no, for those saying it's a browser issue, it sure is not. Steam downloads at the same rates or slower, and other downloaders such as Blizzard's Battle.net app yield the same speed.

I have tried almost all the remidies under the sun I could find, including reinstalling adapter drivers, netsh wlan commands, using system restore, various tweaks and twiddles such disabling IPV6 and I didn't have to change wifi channels, since inSSIDer yielded that there was no interference. The only options I haven't tried yet were reinstalling Windows, moving my PC (which isn't an option) and getting a new adapter.

Now onto my system specs:
Operating System: Windows 7 Ultimate 64-bit
Motherboard: Gigabyte 880GA-UD3H
Processor: AMD Phenom II X6 1090T
RAM: G.Skill Ripjaws series 4GB RAM sticks (x4)
Harddrives: 1TB HDDs (x2)
GPU: XFX Radeon R9 280 (Previously before day of post was a Radeon HD 6870 by same manufacturer)
