Unable to connect to the home base

Hi guys.

It was working fine till I had to unplug my devices.
It connects via Ethernet, but wifi problems.
It will connect but on test signal it says unable to connect.
I have made sure the wifi is correct and 2.4GHZ etc
My modem is working fine, I have tested several other devices so I can 100% say it’s not a modem issue
Any tips on how to fix this?

I remember setting it up initially via ethernet cable connected to my modem first. Then once it’s connected properly, it allowed me to set it up secondarily on a wifi connection (while still ethernet connected physically). Then as soon as it said it was connected via wifi as well, I think I remember unhooking the ethernet cable and placing the Homebase where I wanted it since it was still connected via wifi.

Does that help at all? If not, sorry lol.
