If your AP was running an older release of Unleashed then e.g. the setup & upgrade wizards might not run successfully if you use Chrome/Edge. Try factory resetting and using Firefox to configure.
If you leave the AP configured to use DHCP, but there's no DHCP server available, then Unleashed won't bring up your WLANs. So check your AP has connectivity to your ISP router or firewall & is receiving an IP address lease from its DHCP server. Or if you're manually configuring your IP addresses then go back and hard-code the IP you want the AP to use instead of leaving it set to DHCP and relying on the fallback to 192.168.0.1.
