CapAC 1 vs CapAC 2

I have two Cap ACs on the go in the house but there are some difference I cannot comprehend, well mostly one.
Specifically Under the Bridge Menu and sub-tab of Ports.

CapAC1 shows the following
0- ether1 - bridge - [role] designated port

CapAC2 shows the following
0- ether1 - bridge - [role] root port

+++ What the heck is root port and how did it infiltrate my setup??

The next entry is the same for both as I manually disabled ether 2 (only ether 1 is used being fed from the POE connectors)
CapAC1 & CapAC2
1 - ether2 - bridge - disabled port

The next connection is for both of the 2G radios each cap and they seem fine
CapAC1
2 - DevicesAP1 - bridge - designated port
CapAC2
2 - DevicesAP2 - bridge - designated port

The next connection is for both 5G radios and they are different (and I should note the 5G on the CapAC2 is the one that I cannot connect too nor its virtual AP)

CapAC1
3 - BasementWifi - bridge - designated port
Cap AC2
3 - UpstairsWifi - bridge - disabled port ???

The last entry in the Ports List for both is a Virtual AP running off the 5G radios.

CapAC1
4 - BasementGuests - bridge - designated port
CapAC2
4 - HouseGuests - bridge - disabled port

RSTP
See https://wiki.mikrotik.com/wiki/Manual:Spanning_Tree_Protocol

I am not sure how that explains the differences between the two Cap ACs.
I have never programmed RTSP.
i just want to get rid of that root port designation and get it to designated port like the other Cap AC

Solved, on the error prone cap AC I undertook the following steps.

a. For the Bridge turned RTSP off and then back on.
b. Removed Virtual Network
c. Disabled and RESET configuration for the associated Radio
d. Re-entered appropriate settings for the 5ghz network
e. Enabled the network, and confirmed working network
f. Re-entered virtual AP and configured wifi settings and was able to join.
g. added appropriate vlan settings on bridge and connected. :slight_smile:

Looks like the radio was stuck in some malformed situation???

RSTP is enabled per default on the bridge. If you don’t need it you may disable it in bridge settings.
