Recently got myself a US-24 Switch, initially i was having trouble with it. Mostly because i didn’t have a flat network.
I had VLAN’s setup, i wanted all networking get to be on Vlan 13 a /27 network.
Initially, i got it all working and setup fairly easily but kept getting disconnects. When i’d make IP/VLAN changes.
This is a good starting point for anyone new to unifi switches.
Good references for getting started with a new switch.
