This is a very strange problem to figure out. I happened to two different AP's yesterday and one about a month ago. Both were after lightning storms. I can understand the lightning ruining radios, but I sure wish they didn't take down the entire network.

When this happens, I can get into every ones radios... including the bad one. All looks good, wlan ok, ethernet ok. But, when I look on my AP under registration, I see one of the CPE's LASTIP number jumping around so that it matches other clients. I DHCP public IP's to the client pc's or routers. The duplicate IP's are only the public ones, not the private IP's I use for the CPE's. I have the AP set as a router and the CPE's as bridges, using station pseudobridge.

I sure can't figure out how a CPE can generate a LAST IP of another clients address.

Perhaps is a human with a malfunction?

Hy guys!
Does anyone resolve this problem? I have same problem on bridge network where there are 80/90 Mikrotik client (all station pseudobridge).

I try to upgrade router os on client that freeze entire network, but problem is the same; i try to change radio MAC ADDRES but nothing. The only way to resolve problem is disconnect client or change it with another one.

Pleas help us

Best regards

I have never found a solution for this other than to replace the client. Very frustrating to figure out. This has happened to me twice now. I only found the culprit by de-authorizing clients and watching the last ip field.
