Splitter problem

Tv and internet went out yesterday.  Your advanced tch support grp determined that the problem was with my splitter.  In, out and tap type.  She had me remove splitter and go direct to modem, which worked.  Still no tv.

I have now reconnected the splitter with in from wall, out to modem and tap to tv box.  All working.  I am not sure how the splitter was wired before.  Does it make a difference with which outlet to use to modem?  This has been an intermittent problem which occurs and usually corrects itself overnight.

If it's a two-way splitter it doesn't matter which port that you use. They both have equal amounts of loss.

Hi there @oceans3101! Splitters do need to be changed often since they do not have a long life span as they weaken signal as indicated earlier. Have you been able to replace it with a new one to see if this helps your issue?

Yeah, that is known as a coax cable *tap* (directional coupler), not a splitter. It's typically best to connect a cable modem to "Out" port as it has less loss than the "Tap" port.

@EG      Thanks for your reply.  I was told by Comcast Advanced Tech Support that I should replace my splitter because I was having a problem with loss of internet which would usually return overnight.  The directional coupler that I was using was provided by comcast.  Tech had me bypass the coupler and go direct from wall outlet to modem which restored by internet but no Tv.  I then replaced the cable from wall to coupler in with a much shorter cable and ran out to modem and tap to cable tv box and it has been working for 2 days.  Tech did not mention a directional coupler, they said to remove splitter and when that worked that I should replace it.  From your response is using a directional coupler the proper choice.

Thanks again for your help.

Every environment is different. Which one to use depends on how weak/strong the incoming signal is in the first place. Use whichever one that works the best.
