My new place in San Jose has fiber to the premise, so I signed up for Sonic again. Good bandwidth, Rock solid service.
If you’re in a larger building (15+ units), there are a couple of other fiber providers that may be an option, if building management is up for it.
MonkeyBrains is a wireless ISP. I regularly get 25-40 Mbps from them (though they don’t guarantee that). I’ve had only occasional slowdowns and one outage lasting a few hours. (So, more reliable than Comcast had been, at least for me.) I’d heard rumors MonkeyBrains was planning some equipment upgrades that would let them deliver 60-80 Mbps, but no official announcement or timetable.
It's just such a pleasure to talk to someone who is actually listening to and thinking about your problem, instead of simply reading from a script.
