RouterOS General

Hi,

We sell Routerboards / Mikrotik some time.

Have unprecedented problem in 3 units RB433AH.

After installing the Mikrotik OS version 4.17 the 3 routerboards stayed with the same MAC address and same serial as well as the license ID is the same.

and can not update the firmware.

Originally, the plates had the following serial and MAC Address

Routerboard1
S / N 220820127552705
MAC1 00037F1A5187
MAC2 00037F1A5188
MAC3 00037F1A5189

Routerboard2
S / N 220820127552973
MAC1 00037F1A54AB
MAC2 00037F1A54AC
MAC3 00037F1A54AD

Routerboard3
S / N 220820127552751
MAC1 00037F1A5211
MAC2 00037F1A5212
MAC3 00037F1A5213

After installation (4.17) Routerboard2, Routerboard3 and stayed with the same MAC and License Routerboard1.

Any idea?

Hello,

After installing the Mikrotik OS version 4.17 the 3 routerboards
stayed with the same MAC address and same serial as well as the license ID is the same.

Did you use Netinstall for this procedure?
