Replacement for Arris cornerstone NIU
My Cox internet connection is via a legacy Arris NIU. The coax from the street connects to the Network port and the coax feeding my cable modem connects to the Home port. There are a couple of voice ...

The box would have been removed long ago except it is inside the garage so they did not see it or think to ask. I would gladly pull it and put it a grounding block myself but since the NIU has voice ports/splitters, it will likely change my signal levels when pulled. I will get a tech out to look at that.
What do you mean by voice port/splitter? It has female RJ11 connections of course, because that is where you phone line used to connect to, but now it comes from your phone modem(eMTA) so the ones on the NIU aren't needed. There is a splitter/tap inside the NIU and I even think a low powered amp too. However the NIU was powered with electricity that was sent over the coaxial when the NIUs were used, but now that Cox doesn't, they no longer have the equipment on the line to send electricity through the coaxial to power it. So basically it's a paperweight but one with a splitter inside. So yes, removing it will change your signal but it should just make it stronger/clearer. The only problem that would lead to is if the signal going to your house was already too strong or you were using a amp inside to boost it. I suggest having a technician remove it and then look at your signal levels. For more info, what model modem/gateway do you have?
