aight, thank you
okay, im done flashing so i just change the bssid correct?
or in where?
enable both wifi's 2.4G & 5G networks "need to for option to show up"
Openwrt > Network > Interfaces > Devices
under wlan0 > Configure > MAC address
under wlan1 > Configure > MAC address
gotcha, thanks
changing them both to different end is fine right? like 31 & 32
it should be
lan = sticker
wifi0 = sticker +1
wifi1 = sticker +2
wan = sticker +3
gotcha but mine ends with a 2E so it should be 3E or something?
should be diffrent
so if sticker is 2E
then wifi0 = 2F
then wifi1=30
and wan is 2G? or 31
wan = 31
as long as none are the same they can't conflict
gotcha thanks
only other thing is that i don't think 160Mhz works
depends on location regulations etc
so 80Mhz to get going
im done setting all the mac addresses, now what do i need to do? also my router doesnt have 160Mhz option for some reason
80Mhz is good
now test it
the BSSID has not changed 
maybe reboot
it should show the MAC address you put in
