I am having a strange issue with MAC addresses which are connected to extender.
First thing first. My setup is as follow:
Ground Floor: Router ----> SERVER2016 (DHCP, DNS and Unifi Controller ) [Cabbled to router]------> UNIFI AP1 [Cabbled to router]
2nd Floor : RE650 (Extender mode) [Connected to Router with WIFI 1]
ZOOM IN to RE650:
Broadcast on RE650 is switched OFF both 2.4Ghz and 5 Ghz.
Ethernet Cable from RE650 connects to unmannaged switch which than provides connection to UNIFI AP2, Home PC and a HP printer. (all wired through unmanaged switch)
Devices have no issue getting Internet or communicating to each other
All Devices connected to RE650 seems to be showing same first three OCTET of there Mac Adresses Only last three OCTET match the real MAC address.
Device1 has C0:EE:FB:25:A0:8D connected to UNIFI AP2 and it gets DA:0D:17:25:80:AD (wireless connection)
Device2 has 50:E5:49:3B:05:E8 connected to switch which is connected to RE650 and it gets DA:0D:17:3B:05:E8 (wired Connection)
Same devices connected to switch and UNIFI AP1 on the Ground Floor shows the correct and ACTIVE connection in DHCP.
Due to this, devices gets 2 different IPs which works one at a time of course depending on where the mobile device connects to UNIFI AP1 or UNIFI AP2. behind the extender or before the extender.
My question why the extender is doing this and how can i setup the extender to NOT do whatever it is doing to the first 3 OCTETs of MAc addresses.
