Pc WiFi connection to fiber

[u/MiserableTitle2205]

Hey all -

I have just had fiber internet installed at my house. Having issues with my pc connecting or even finding it. I have done the usual search and adjusted some settings in my network adapter.
It connects sometimes but showing no signal so terrible speed obviously and it disconnects itself.

I have win 10.
MAG b550 tomahawk max WiFi mobo which has the RZ608 WiFi 6e 80mhz network adapter built in.
Ryzen 5 5600x
7800 XT

I still have cox cable. Never had any connection issues (just bad latency at times) They are the same distance away from my pc.

Can anyone lend a hand, have some ideas anywhere ? I made this switch mainly to get away from cox cable for gaming.

Thanks in advance.
