MR33 - DNS Misconfigured & Uplink IP Address conflict with another device

[Niggy11]

Hi two of my MR33 access points are behaving strangely

1st one goes from Online to Alerting every few hours and says IP Address conflict on up-link.

2nd one says DNS Misconfigured.

While all my other access points are working fine.

The network is straight forward ISP Modem > Router > PoE Injector > MR33

I'm using a Mikrotik Router on this setup.

How should I tackle this problem?

If you run a packet capture on the wired side of the AP you will be able to check the packet capture and see if another device with a different make address is using that IP address. Or why don't you change the IP of the access point to another unused IP, does the issue persist

If you change the DNS to 8.8.8.8 do you still see the DNS misconfigured issue?
