I think I have found the culprit.
On normal boot, while connected through ethernet, I don't have any issues connecting to problematic websites. In fact, all sites actually load faster (latency).
While connected via. Wi-Fi, it loads slower, and I can't connect to my problematic sites (original problem).
So It brings to two conclusions. It's either a driver issue or a hardware issue.
I am already using the latest WiFi driver, so I can't do much on this front.
My card is not one year yet, so I still have warranty coverage.
I have the TP-Link T5E if anyone else is wondering.
Presently, I am connected via. Powerline over ethernet, it's a pretty old adapter, I can only get about 15/8Mbps, so this is only a temporary solution.
I would prefer my next network solution would be anything else but another WiFi card as this is the 3rd one that I've tried in the past year where I've experienced issues with and had to return.
Thanks to everyone that had helped.
