Re: X1 TV box

Just replaced my 3 legacy Xfinity boxes with 3 X1 boxes. The old boxes were all working just fine.  The new hub (large) X1 box will work at any of the 3 old box locations just fine. The 2 smaller boxes will either not connect at all or connect & then freeze saying they can't connect to the internet depending on where I connect.  I do have multiple splitters on the coax (lots of TVs besides the X1 boxes). Is there any hope of getting the small X1 boxes to work without rewiring all the coax connections/splitters?  If not, my last resort might be to just replace the small X1 boxes with HD TV adapters.

Things worked better than expected.  I the back-to-back 4 way splitter with no Amp at all seems to work.  Even more interesting, I measured all of the cable lengths and each segment was roughly 100 feet long.  So the two farthest connections (between the hub and the smaller boxes) had roughly 300 feet of cable between them.  Right at the specified limit of Moca...but it seems to be working fine.  Thanks for the discussion, it helped alot. I found this white paper for moca custom installers & system integrators to be extremely helpful.

Your main box will work fine, like you proved. But the smaller boxes NEED the ability to communicate with the main box to work properly, there’s no way around it. The boxes use moca to communicate, the more splitters the harder it is for those boxes to talk. The more splitters, the more signal problems you’ll have. Downsize your splitters to what you absolutely need or reconfigure them so the X1 boxes are ahead of everything else in the cable configuration. The legacy boxes didn’t need this as they are all independent. Adapters don’t have all the channels or access to features as the X1 boxes do. Using the Xfinity stream app on a Roku is another possibility as a cable box substitute, if you’re not able or don’t want to change anything in the cable configuration.

I attached a copy of my home wiring diagram (hopefully you can see it).  The first 4:1 splitter is where we did an addition to the house (so Man Cave is in the addition). The Family Room & Lanai are the other two locations I'm trying to use X1 in. I'm thinking the best case scenario is to replace the 2:1 with a 3:1 and have the Family Room & Lanai connect there. This avoids the Amp & the 8:1. It would be the most convenient to have the hub (large X1 box) in the Family Room.  What would you suggest for a configuration?

X1 boxes need to be on the same side of an amp, moca won’t pass through reliably. Any amp should be before splitters, there’s probably not much to amplify after 2 splitters. The amp posted (there’s also a 9 port) would replace the four way but you can’t possibly need every cable outlet live. Reduce splitters to what you are currently using. Those extra unused outlets could conceivably introduce ingress (noise/interference) and affect your boxes.

I'm in a pickle....I think the minimum I can get by with is two separate 4:1 splitters...with one feeding the other. First splitter is in the addition and feeds the modem, 2 TVs and about a 50 foot run of coax to get to the main house central box. From there the other 4:1 feeds 4 more TVs.  (1 X1 box is in the addition, the other 2 in the main house) I think your solution is to make the first 4:1 splitter the amp....but it's currently in an attic with no convenient access to an outlet. Would that configuration work if I could make the first 4:1 be the amp?

Glad you got it figured out. If you ever need the amp that I mentioned, you can have remote power through port 1 of the amp to a cable outlet, it doesn’t need a close power source

Thats good to know about the Amp being "self-powered".   Does it still transmit signals even if its not powered?

Only the Voip port works without power.
