You've described a technical problem, not a non-technical problem.

I'm not familiar with that device, but a non-technical user might not care about that "problem", as long as their device does the task they are intending to perform.

The problem is being described technically, which is more useful than the non-technical description of the problem, which is "I don't know, the Zoom isn't working, and the kids can't watch their Netflix at the same time".

Yes, but Zoom and Netflix will work great on 50% or 25% of 1gbps. Heck, they'll work great with 5% of 1gbps.

I am sure that AT&T's CPE equipment is lackluster, but that doesn't mean it won't work to do basic tasks to the satisfaction of a home user.

I dunno what to say, but it does not do basic tasks to the satisfaction of people who buy 1gb internet connections.

I can tell you from experience that large downloads and uploads cause latency-sensitive applications to stutter in a way that is fixed by using ubiquiti gear.

In your defense, you did say non-technical household, but I dunno -- I don't think that wanting to use, eg, backblaze for backup and not have that tank zoom makes you a technical household.

And I don't know anything about the equipment AT&T is handing out these days, it could be particularly bad. But generally speaking the equipment that ISPs are handing out these days is pretty functional for generic use.
