Perfect, the Cat6 does fit the requirements to support gigabit internet. It is possible one or more of the cat6 cables need to be swapped out, however, if the cables are fairly new they are unlikely to be causing this issue.

How many devices are currently connected to your internet at this time @JoeMartino006?

Just one laptop to the back of the modem.

Thank you for confirming how many devices are connected @JoeMartino006. With only one device connected to your internet, there wouldn't be any other devices causing the internet to be slowed. The laptop itself may not be capable of achieving higher speed depending on its specs.

At this time, I'd like to double-check the signals going into your modem and make sure there are not any issues occurring in your area. Could you please send our team a direct message with your full name and full address?

No updates, still not getting anything above 900mbps.

Unless your laptop as an Ethernet port greater than 1 Gpbs, you would not be able to receive speeds over 900 Mbps a majority of the time. Unless you have a 2.5 Gbps Ethernet port or higher, it is very rare to receive over 900 Mbps. Due to Ethernet overhead, actual download speeds are limited to 940 Mbps over a hardwired connection in perfect lab conditions with acceptable computer resources. Would you be able to perform a speed test by visiting our Xfinity Speed Test web portal to determine the speed being delivered to the modem?
