only 1 splitter from street to house. i disconnected the cables not being used on splitter so pretty much just 1 cable all the way along the outside of the house thru to the input inside. cable was ran by cox tech when i started their service about 2 years ago and are in good shape as i can see it the entire way. i do not have any new electronic devices. my family use is very basic, ipad, internet tv, and that’s it. there are a quite a bit of people having the same issue when i search in forum and intnernt but there never seems to be a solution. i think the software in modem is corrupt. but then again, i’ve swapped out 1 older model and 2 same model modems with cox and still having issue. all the modems are from cox arris.
