Well .. if anyone is interested/having the same problem
I finally got around to just loading DD-WRT
I made a 2.4 ghz band and a 5.0 ghz band. Piggy backed a virtual network onto the 2.4ghz band and enabled AP isolation (not ideal or as good as getting a second physical router from what I understand, but it's free).
Was able to turn on QoS and access restrictions to restrict p2p ports, and set a macid priority with my computers at the top, and theirs at the very bottom. So far it's been working flawlessly and internet is faster than ever
