Oh lord. Don't even get me started on cox. My family pays for 150 mbs wifi and we don't even get close to 70. On a good day, it might go past 75, but on a bad day, it throttles itself to 50. I called them to complain about this slow internet speed I am getting, and instead of helping me they bsed even more about how I'm in a spot with low connection(keep in mind that my friend lives in the same community as me and he uses at&t and gets 120mbs when they only pay for 100mbs).
Overall, I wouldn't recommend cox to anyone, and I'm planning to switch out of it asap when my contract with them ends. Their marketing is bs; they have bad customer service and horrible internet speed.
