Main X1 box horribly slow, satellite box instantaneous

As the title states. It's been this way for a while and we've lived with it. Got a new main X1 box a month or two ago hoping that would fix it, but it's still lousy. Apps especially are very sloe to navigate.

Any tips?

Thanks.

When that happens you can try changing the batteries in the remote, rebooting the cable box, and checking the coax (or fiber) line and connections.

Thanks for your reply! I have done all of these things, as well as performed the "system reset" functionality which I found in another thread of this nature.

Main X1 box horribly slow, satellite box instantaneous

With older legacy cable boxes, when the box received a signal from a remote it acted on that signal directly. I believe digital adapters still work that way. But X1 boxes are different. When using a remote to control an X1 cable box:

The remote sends a signal to the box
The box uses an internal modem to send that signal to a server at Comcast and ask for instructions
The server at Comcast decides how the box should respond and sends back commands and data
The box receives the commands and data and does as instructed

This design means that X1 is very flexible, but more delicate. The chain has many more links and if any them are weak or broken, the response to signals from the remote is sluggish, or fails completely. When that happens, if changing the batteries and rebooting the cable box does not correct the problem, you may need to check the coax (or fiber) line and connections.

And if the remote still doesn't work properly, you'll probably need to ask Comcast/Xfinity to send out a premise tech to troubleshoot the problem. If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast/Xfinity originally supplied them) you'll probably have to pay for the visit (approx. $100) unless you have their Service Protection Plan (https://www.xfinity.com/support/articles/service-protection-plan, closed to customers that don't already have it). If the trouble is due to a faulty Comcast rental device or anything outside your home you shouldn't be charged.
