4k Box Eating all the Signal from Router?

Using a cable splitter, when the cable is plugged into the 4k Cable Box, the modem is super slow running at 25 percent speed or less. When I unplugged the cable from the cable box, the modem is back up to 95 percent or over for speed.  How do I get full speed for internet and have my 4k cable box plugged in at the same time?

Thank you for reaching out @user_g8q78l! It sounds like the splitter may be bad. Are you able to stop at a local service center to pick up a new one? If you are needing any assistance in locating a service center you can follow this link: https://www.xfinity.com/local/store-offers?linkId=79599175&q=32.48128%2C-110.9147648 to locate one near you! I would also suggest if you can to use different outlets for the modem and your cable box. I have this set up in my own home and do not have issues with my modem or 4K box.
