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.
Solved! Go to Solution.
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?
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?
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.
