Hi Bootman, it sounds like the signal to each of your devices is impaired. There could be an issue in our equipment outside your home, or perhaps a splitter inside your home has come to the end of its lifespan and needs to be replaced. You can test this theory by temporarily bypassing the splitter and connecting one of your cable boxes directly to a cable outlet. If you are still missing channels, I suggest a service call. If all your channels work after bypassing the splitter, pick up a new splitter at any Cox retail location or big box store. -Becky, Cox Support Forums Moderator
