ATT Fiber stuck on 100mbps for 1 ethernet device?

[Optane^]

My roommate moved into my office and I went to my bedroom. Plugged everything hardwired and now my PC is negotiating to 100mbps and he's on 1k mbps?

 

Modem is a BGW320-500, software 4.23.4

 

Changing ports doesn't matter. It's like it can only handle 1 1gig connect at a time. Called support and they're sending a new modem.

 

Any ideas?

Does your bedroom ever get 1 Gb/s?
I mean, have you tried unplugging the device in the office and observed that your bedroom PC gets 1 Gb/s?
I doubt that is happening.

My bet would be: bad ethernet cable.
Change the ethernet cable running to your bedroom, or redo the connectors (re-crimp the RJ-45s on both ends).

It was the wall jack.
