I have perfomed 2 changes:
- I have re-seated the R11e-2HPnD card
- I have changed the antennas between them, by switching the connectors. Now the 2.4 GHz AP is using the former 5GHz antennas and the 5GHz one is using the former 2.4GHz antennas.
Regarding power supply, unfortunately I don't have another one.
What about antennas? Is there any way to see in RouterOS if the antennas are good or bad, or if one of the antennas has a connectivity issue?
I'm thinking that maybe there could be some radio params in the OS that can be checked, in order to see if all antennas are detected and they're emitting/recieving functions are ok or not.
