Yeah, agree. I'm having a hard time getting my pool controller connected and they pool company (Zodiac) is closed for the holidays. My Nest thermostats would never connect to the Suddenlink gateway.
I cutover to Suddenlink from AT&T a few months ago due to cost/speed differences, 3x the bandwidth and 40% cheaper. But Suddenlink's modem is a blackbox, you can't do anything with it. So I bought a new modem and some new wireless gear, much better now.
