I recently purchased a CBW140 and replaced an existing UniFi wireless network with it. I am very pleased with it, and I moved to disable the entire UniFi network and installed a CBW145 in wall unit to replace an existing UniFi unit.
However, when plugging the 145 into the network, it boots up, but does not find and link to the Master AP, the one I installed a few days ago. According to all the documentation I have read, the 145 is supposed to look for a master, and once it finds it, self-configure and provision itself with the Master AP. For some reason, this is not happening on my network.
Topology:
140AC (master ap): Core Switch > Intermediary Switch > 140AC
145AC (new subordinate): Core Switch > 145AC
Both switches have VLAN 99 (my management VLAN) as the native untagged network configured for the ports the APs are connected to, and plugging my computer into both ports instantly gives me a DHCP address from that VLAN. This confirms that both ports are operating as they should, giving out a native VLAN 99 connection.
However, the 145AC does not get a VLAN 99 DHCP at all, and in fact, gets an IP address which should not be possible on my network on any VLAN. The 145 does not appear on my pfSense DHCP lease status at all, but UniFi switching shows it having an IP address of 192.168.0.101, which is impossible.
I am confused on to what's happening, and if there is some issue I am missing. If you need me to provide further detail, I am able to.
Thank you.
