I came home from work about 2 weeks ago and it felt like my internet was faster. After hard wiring to my router (I do power line networking) I found that my speeds where doubled! I received an email form them saying this was going to happen, but I was not expecting it to come to where I live this fast.
I am getting about 121 down and 5.5 up when hard wire. As well as 37 down and 5.6 up though power ine.
I am not saying that Cox is the best ISP out there, but better then the "competition".
