Question Constantly dropping internet connection, tried everything

Okay, I just signed up here because I've given up hope of this ever being solved.
I've tried just about everything and nothing has fixed it.

This has a slight bit of backstory actually;
Months ago I had my internet working fine.
I got 2 new wifi adapters since my old one (plug-and-play usb w/no antenna) had slowed down to 2mb/s connection and died.
So I got my new adapters, a wireless USB adapter w/antenna built for dual-band connection, I bought two just in case.
I plugged one in, installed the drivers from the CD that came with it and it was fine.
10-15mb/s internet, everything was perfect. I could work, I could play games and it was okay.

Recently my PC died/refused to boot.
I later found out it was because of a corrupt bootres.dll.
I fixed my PC and reset it, choosing to keep my files.

I re-install my network adapter via the CD, plug it in.
Every 5-10 minutes I get cut off. The dreaded yellow triangle shows up and the state of my internet switches to "no internet"
Every other device on this network has no issues, only mine.
There are only 3 devices on this network at a time and majority of the time it's just mine.

I'll list some things I've spent the past week trying, to no avail;
Complete network reset via settings in windows (before and after everything else)
Every netshell and ipconfig command you can throw at me
Reinstalled the device numerous times
Installed multiple realtek wireless (and even wired) drivers thinking it would help and then uninstalled everything and re-installed the base drivers
Changed power profile options to prefer maximum performance
Disabled "allow the pc to turn off this device" under device properties (after every clean reinstall)
Switched the first usb for the second backup I bought, changed nothing
Closed, re-opened/restarted the realtek wifi lan utility
Tested the connection with the lan utility closed and open, neither were any different
Disabled ethernet connection, no change, re-installed ethernet, no change
Disabled firewall
Enabled the ports for everything required
Did every reset my router control panel has in it

I recently installed some drivers
and despite it being the same things I tried before, I can actually hold a connection now for a while (didn't test the time inbetween d/c's)
but it appears to be around 20-30 minutes yet I continue to get disconnected.

I ran MiniToolBox, selected all boxes and hit go
The only issue I see among the logged info is within the system event log:

The brand of wifi adapter is TechKey AC1200 Dual-Band Wireless Adapter
My PC didn't come with a wifi card installed, so this is my only way of getting internet

If anyone can help, I'd greatly appreciate it, I need the internet for the work I do and since cannot access internet.
Even when I'm gaming or watching youtube, I get kicked off of the game or my videos stop loading and I have to re-connect.

Does your connection return on its own? I have this same device and it will frequently lose connection to the internet, my temporary solution has been to just open the wifi menu and click disconnect then reconnect which brings the connection. Also looking for a solution before I ditch this adapter and try a new one
