Is there a max coax cable length for the goCoax Moca 2.5? I have 3 cables going from my basement to my upstairs room, totaling in about 100+ feet of coax. I did log into the goCoax unit and I am getting the correct rate from one box to another through the management page(3300). I am not sure if it is the cable length itself or one of the cables not having a good connection. Wanted to ask this question before I start ripping everything apart! Speed difference is 500/500 in basement and 85/60 upstairs. I took out all splitters and have direct connections from cable to cable.
