It's funny. I actually got AT&T Fiber like 6 months ago, but they force you to use their terrible all in one unit. I'm a fairly tech savvy guy, but for the life of me the best I could do is run my dedicated router in parallel. There is no way to get that BGW-320 unit to just act like a modem.

The speeds were good when they worked, but the signal was so fucking unstable. My wife and I work from home and the internet would go out long enough to get disconnected from meetings like 5 times/day.

So yeah, went back to Spectrum. Got a great deal for $30/month for 500mbps down for 2 years. Don't miss fiber at all since I can use my own fuckin hardware again.
