This is a scam by Cox. I called the number and the rep confirmed this was nothing but a ploy to get people off the old 300/30 plan. I'm filing a complaint with the OKAG and advise anyone else impacted to do so. There is no "technical/Network upgrade" Cox is doing to require a change like this. This is their way to get people to either A. upgrade equipment or B. upgrade plans so that they do not have to Grandfather us in. The 500mbps they are offering if you do not change your modem is a joke, as A. you'll still be capped at 300mbps down, and B. your upload speed is being DOWNGRADED to 10mbps
