TL-AC1500 (T8E Archer) / BCM4360 - Terrible connectivity

I have a TLAC1500 that shows up in my wifi adapters, shows me some wifi networks (some, not all) and connecting works only with those less than 1 feet away. Anything farther doesn't work. The networks are 20hz channel 6-11 on a router that supports b/g/n.

It works perfectly in windows. My google fu gave me some patches but none of them worked for me in either Sierra or High Sierra.

Any help would be greatly appreciated. Cheers.
