Locked Upstream Channels
On the Xfinity gateway I was seeing at least 5 locked upstream channels. I just purchased a new Arris S33 cable modem DOCSIS 3.1 32 x 8 and I am only seeing 4 upstream locked channels and my internet is half the speed that it was or more. I am on 1000Mbps plan and I am only seeing at best 300Mbps. When I hook up the Xfinity gateway the speed is normal and getting around 850>900Mbps. I read more locked upstream channels means more speed. Does anyone know what could be going on? This is also my 5th cable modem so far in the last month trying to get speeds at least close to what they were with the Xfinity gateway. Do I need to take my Arris S33 to Xfinity to have them adjust some settings or can they do this over the coaxial cable?
Thanks for any help on this as this is getting very frustrating with losing all this speed when using my own cable modem, 5 different ones, and then plugging in Xfinity gateway to see normal speeds, or reasonably normal.
