Well i Got the Internet 150, ive had it for a week now and have Yet to be able the 75Mbps down limit as of yet , I speed test from different locations allover, ill run anywhere up to 10 speed tests a day or night (anywhere between 2-4 am) I get the full 30Mbps up but my downloads are not even half for what I am suppose to have, Here is another Kicker, my Qptic TV now buffers aprox 4-6 times an hour any time we are watching the TV this does not seem right. I just thought I would ask befor I call Tech Support...
Go into your router menu and then to Status. Under Line 1 and Line 2 check the bottom of the table to determine the quality of your copper lines if that is what you are using. Here is an example of one line. I have 75 service, and it looks like the lines could support 100, but not 150.
