I have an ethernet cable going from the modem to a Samsung Home Pro Connect (router).

Hi and welcome to JustAnswer, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially and to avoid asking you to do something you've already tried, can you please tell me what / any and all troubleshooting / specific steps you've already attempted other than / to address the above.

Still, have you tried:

  • check/replace the HDMI cable;
  • try another source/device (such as HDMI equipped laptop, DVD/Bluray player even if just for test purposes to replace the ARRIS RNG150N.

This is an independent site and members of this online community provide information, repair tips, technical assistance as a form of paid Q & A service.
