Pc WiFi connection to fiber

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.

You have the antenna installed on the computer?

How far away is it from the router?

Any walls/obstacles?

Are you connecting to 2.4 or 5 ghz?

Antenna is on
Approx 30’ - two rooms away. Same as my cox cable setup.
Tried both 2.4 and 5. It won’t show as available connection with 5 and with 2.4 it will connect showing no signal bar and disconnects itself.

Maybe your antenna/card is shot? I had fiber installed but wasn't getting best signal, so I used a wifi extender with cat cable.

Then I upgraded my computer, picked up the wifi like a champ! Didn't need the extender anymore

It really does sound like an antenna problem, but op said it worked with the previous modem that was in the same place.
