Can I have two modems?
I have a cable modem in my home office which connects to a router. My primary television is in another room. There is a coax cable running to it that provides the Xfinity signal but it relies on a wifi signal for my other streaming apps. I thought that the apps would be faster if I had an ethernet connection to the television instead of relying on wifi.
So here's the question: can a put a splitter on the coax line behind my television, run one line directly to the television and run the other to a second cable modem, then run a line from that to my television for the apps?
Thanks.

In most markets you can't have two cable modems/gateways at one address. That might not be true everywhere, but it would be kind of silly. You'd be paying two bills.
Depending on EXACTLY what you have, you might be able to get a pair of MoCA adapters to work. They convert coax to Ethernet using your existing coax wiring. I don't know how well that would work with your existing cable box if you are using one of those (I don't use their cable boxes or cable lineup), and I'm not a fan of installing splitters. Splitters can cause a lot of signal degradation issues. You'd have to read the manual for what you end up with and try to figure out if it would work with your equipment.
Running Ethernet from your router to the TV where you need it would be ideal, but that isn't always practical to pull wires and install jacks.
If the problem is extending WiFi range/signal quality, adding an Ethernet connected WiFi access point closer to where you need it, or as an alternative, using a WiFi mesh network is good at this type of thing without drilling holes. To pull down a full 8K stream from a provider, you would only really need around 40-45 Mb/s, which is easily doable with WiFi if you have a good signal. Then you'd also have good WiFi for everything else.
They say powerline adapters can also work. They use your existing AC wiring. I've never tried them. Perhaps others have or have a better idea, or more experience with MoCA adapters and Xfinity.

Hey, @ssif21! Thanks for reaching out to us on the forums! I hope you are doing well. Having a look at what @flatlander3 had mentioned all seems to line up with what we would recommend. A network extender or a powerline adapter. I've personally used the powerline adapter to get a signal in a room that could not get Wi-Fi at all and was getting about 80 Mbps download speeds on it even though the adapter is capable of 1 Gbps. That is all based on how your electrical wiring is set up in the house. Please let us know if you have any more questions.
