Cox is throttling speeds of DOCSIS 3.0 modems
I used tohave250-350Mbps down 2 years ago but Cox has throttled down some older DOCSIS 3.0 modems to only have access to the essential 150mbps speed. If Cox didn't have a monopoly on internet service providers in my area I'd switch ASAP. Probably just trying to sell more of their junk modem rentals to unwitting customers and take advantage of their lack of knowledge.
