In my experience, Charter Communications has the worst broadband, cable internet service of any company I've ever dealt with. Their tech support has been lousy. I just moved into a new apartment and the only cable broadband available in the area was from Charter. From day one the service has been terrible. My supposedly "always on, always connected" Motorola SURFboard SB5120 cable modem has to be reset 50 times a day because the cable signal is too weak to keep a connection. I've even had a Charter technician sent to my home to try and fix the problem to no avail. He simply replaced the cable running into my house and tweaked something on the line outside. Before he left, the technician assured me that he would call me the following Monday to check and see if what he did helped fix the problem. And, of course, he never called and the problem is still going.
So, in frustration I've had to call Charter back several more times. This last time, the support person told me that my cable modem was probably going bad and that I would have to purchase a new one. I told him that this was ridiculous because I just paid $75 for the one I have and it's only 6 weeks old. What a rip-off! Charter expects me to buy another expensive modem within 6 weeks of service. I think I'm going to try DSL and give up on Charter Communications once and for all. I'm very disappointed in their service.
