Oneplus 6T 5G Wifi not working

[garthvater111]

Basically my 6t stopped connecting to my wifi, claiming it had an authentication issue. i verified my password, it being correct, ive reset my router and played around with it a bit. I have smart stearing enabled as its very convenient, however when this is enabled my phone will not connect to the wifi. when disabling it, my phone will only connect to the 3.4g band and has the same issue with the 5g band. Also when setting a rule that the mac adress of my phone is to connect to the 2.4g band, it works as expected. Its a band aid fix however and i would like to know if there is a proper solution. most other people with this issue seem to just be told its their router from what ive read googling around (my pixel xl and laptop have 0 wifi related issues, its not my router)
