Cox cable at my house has almost never been as fast as they are supposed to provide. I test it at internetfrog.com and use the speed test to find that I most often get less than 40% of the 1.5mbps downloads and of course the upload speeds are close to dial up speeds.
Also the internet just shuts off sometimes and on my cable modem it shows Cox to be Offline. When I contact customer support they try to throw the problem back at me and when they figure out I am not the person on the bill they use that to avoid fixing the problem by asking me to provide personal information only my landlord would know.
The Basic cable has awful reception on the upper channels and most movies will pixilate or provide those blotchy areas. Then we get a one to two second service disruption where we get the blue screen and the error message instead of a signal on the TV. We need to have some prosecutions of Cox senior staff before they will finally provide the service they advertise.
