If that is your experience then thair guided setup has improved a lot over the years, besides configuring VLANs later because I have a few talkative devices on the network and I don't want crosstalk I didn't had to do anything other than to run their setup.

It configured the WAN interface, created the switch interface with the number of LAN ports I wanted, forced me to change the password, suggested that I should change the default username which removes the ubnt default username system completely, asked on which interfaces I wanted to turn UPNP on and enabled the firewall by default.
