R6800 MAC adress
Hello, i hav one problem with my R6800 router. Router is changing LAN MAC adress after every reboot. If i use button "reboot" on router information, after reboot router has new LAN MAC adress. ...
What lan mac address? Where are you seeing that?
Just checking for clarity
Hello plemans
I am using Wake me on Lan for checking what is actual MAC adress (it is the same as on advanced settings) Adding Pictures of actual mac and "todays old macs"
Router is on own lan with one VM machine only. For testing. When i press "Reboot" button, Mac adres is changed in boot process.
Not really paid that much attention to it before but my understanding was it was a static address as well.
I am on IT about 30+ years. Never meet the router or any other device (except mobile phones using random MAC, which is security function and can be switched off) that is changing its own (LAN) MAC address. NOT IP ADRESS! MAC ADRESS.... ...MAC adress is HARDWARE identification of the device, It cannot be changed easy! (except cloning mac on WAN port... which is a function)
Layer-2 isolation o AP's is based on MAC address. If you add router/dhcp server/gateway MAC and then that MAC is changed on router restart... ...all layer-2 isolation on guest network on that LAN is useles.... ...no internet as guest's cannot communicate with selected MAC adress that is gone....
For most windows client change MAC adress of the router/gateway which is DHCP active means a mayor network change...... ...more problems.....
