Big lack of configuration options mostly, but also for some reason intermittent DNS performance/resolution that I never had before. Problems accessing my local network server intermittently. More issues with bufferbloat as well from my testing. The general responsiveness of the connection feels off from time to time on multiple devices, I think it may be that.
Probably more jarring as I had a MikroTik router which had so many options, so going to a Hub 5x was like going from engineering a skyscraper to building duplo.
I never tested the WiFi. I’m sure it’s alright and they will give you range extender pods I think, can’t comment on those.
There is a DMZ option so that’s what I’m going to try and use with my old router. If that works well, then I may upgrade the router to one that can handle the throughput (old one can’t I think). May get one with SFP input so if modem mode never comes I’ll go the route of an XGS-PON stick with custom firmware. It’s just a lot of expense for something VM should just support out the box.
