@wacjames10 You need to set that to approximately 10% of your topline speed if you are wanting to use smart queues / QoS. I assume you are not a new customer or are in the process of having your line undergo a relearn (as its during this 10 day period that the speed may fluctuate)
The better way is to speak to cuckoo support and ask to see what your line speed is; failing that make sure you only have one device plugged into the unifi unit and wifi is turned off (to ensure no other devices are connected) and then run a speedtest. Whatever speed you get here take 10% off and then put that in your smart queues; remember there are values for both downstream (download) and upstream (upload).
As an example; if fast.com gave you 70mbps down and 10mbps up; in smart queues you would put in:
Download: 63mbps (63000kbit/s)
Upstream: 9mbps (9000kbit/s)
I would only enable smart queues / qos if you have congestion on your network; if you dont have this issue or need to prioritise traffic then i would leave it off.
Re: auto-configure; it just sounds like you have let the unifi itself set the internal LAN ip range but i could be mistaken - im not staring at my gateway at the moment but if you could take a screenshot i’d be better placed to answer
