Ethernet port issue

I have the xfinity xb7-t modem and I’m having an issue with my Ethernet ports. Whenever I plug the Ethernet in the light on the back blinks red/orange and this caps my speeds at 100 mps. I was wondering how can I fix that and get it to blink green. I’ve called xfinity for help a number of times and they’ve sent out 2 technicians with no solution. Btw I have the 1200 mps plan. I’m having no issues with the WiFi and when I test that it’s usually around 400mps. And I’m also using a cat 6 cable

Does the device you are plugging in have a Gigabit ethernet connection?  Generally speaking, when an ethernet port blinks orange, it can indicate a half duplex connection.  It can also indicate that the device being connected is only capable of a 100 MB connection.  This will vary according to the device you are plugging into.  Since you do not provide what you are using as your modem or modem/router, I cannot guess which it may be in your case.  Please see the following link:

FWIW, they wrote "XB7-T"

@NoNoBadPuppy thanks for you help. I’m plugging in a ps5. It’s supposed to be able to handle up to 1 gb to the Ethernet port. I’m using the modem/router that I got from my isp (xfinity). It has 4 Ethernet ports, 3 1gb ports and 1 faster, 2.5 gb I believe. Xfinity calls it xb7-t. I’ll check out that article. Thank you again.

Also double-check the cable. Some cheap cables only have 2 pairs (4 wires) and can only run 100Mbit. Look at the connectors at the ends to make sure you see all 8 in use.
