I’ve been with Cox ever since they started offering Cable internet back in the late-90s. Never had a problem with them, but I did switch to AT&T for a short while to check out the competition. I quickly switched back to Cox after realizing AT&T’s speeds were shit.
Just ran a speedtest from North Park, currently a “Premier” subscriber:
I purchased both my modem and my router. I work from home so am very sensitive to speeds/service and have never really had a complaint with Cox. About 6 months ago I cut cable and only use Cox now for Internet services. We stream a shit-ton of Netflix/YouTube/Spotify/Pandora and have never had issues.
I’ve read recently at Broadbandreports that speed increases are coming soon to SoCal. Check out the forum there, lots of good info on Cox.
