Cox hasn't found any solution or offered any compensation or other offers, just an oh well for a fee of $100 we can have a tech come out and look at the cables and see if theres a problem.....Really? ANOTHER $100 just to see if it might possibly be the wires? Re: VERY slow upload speeds and normal download speeds... Welcome to Cox Cable. We're signed up for Gigabit, and we're still getting about 700 GB below what was promised..... and intermittent service despite being connected via ethernet..... They're trash but still the best option in my area for now. We're switching as soon as att fiber gets setup in our area. 5 more moths!
