Xbox is saying it can't connect to the WiFi even after factory reset. Can I get help?

I tried a factory reset and it didn't help.

The xbox has no wifi dongle and is connected via cable.

I tried giving the xbox a static IP and adding port forward rules in the router, but that didn't help.

I am in the same predicament as Nick cole44. My console shows that is connected to the internet via Ethernet cable but no cable is connected at all. I tried to setup through wifi but none of my wifi options show up. I factory reset my console now I can't even access the dashboard.

I tried the soft factory reset and it reset but once I got to where i had to connect to wifi, i put in the correct wifi password and it still said i can’t connect. Should i do the the factory reset and delete all the data?
