Cm600 connection issues xfinity
I've been having connection issues with modem on and off for about 6 months. It usually happens when my router, or modem loses power and starts back up. My router is a asus RT-AX86U Pro running asuswr...
- So xfinity tech came out today and traced my coaxial cable back to a splitter. My apartment complex is old and the splitter was hidden. To make it worse, the previous tenants set it up with the input/output cables reversed. That combined with my older modem is what was causing the issues. The tech removed the splitter and my old router is now able to connect to 4 Upstream channels.
I'm also getting a new modem this weekend and went with a surfboard sb8200.
Thanks everyone for the help and input. It's much appreciated. Happy Holidays
