CAP's ident conflict

Neferith · Fri Aug 03, 2018 11:10 am

Hello All,

I have problem with 1 of 4 APs which are managed by CAPsMAN. For AP01 I get errors:

AP01 is being disconnected and connected again. Cable is OK (different AP works fine on it). Other APs work fine.

I noticed double cerificates on CAPsAMN, so I revoked both of them:

It didn't help.

Do you have any suggestions what might be wrong?

For those who had the same problem: Solution is to manually set MAC address for Ap's bridge. Use Ether1 MAC address.

Hi @Neferith, I got the same issue :
caps,error removing stale connection [mac_add/13/fef4,Run,CAP-mac_add] because of ident conflict with [mac_address/13/2b39,join,CAP,MAC_address]
I am fairly new on mikrotik and I not understand how to implement your solution.
Could you please explain how you did that and if (after so long time) the problem was fixed and stable?
Thanks

I'm having the same issue, briege MAC Address on both AP are using AP's ether1 MAC Address. My Bridge has a static IP Address and I'm still getting that error logged and my SSIDs droping when it happens.

I someone else has any additional help I will appreciate it.
Thanks
