Hello everyone and thanks for helping in advance. I installed OpenWrt on tp-link Archer C5 v4 which is used as a bridge to main router, it works and everything is great. Tried to change MAC for several days, I read official OpenWrt docs and many OpenWrt forum topics and other forums how to change MAC. Nothing worked. Override MAC address option in LuCI didn't change it, but override changed lan MAC from GUI interface. I also tried these commands via SSH putty.
uci set wireless.radio0.macaddr='XX:XX:XX:XX:XX:XX'
uci set wireless.default_radio0.macaddr='XX:XX:XX:XX:XX:XX'
uci set wireless.wifinet1.macaddr='XX:XX:XX:XX:XX:XX'
They didn't change MACs but also totally stopped wifi processes. I tried write MAC addresses in lowercase and uppercase, no effect.
May be it is a bug in this exact firmware or conflicting process or conflict between OpenWrt and hardware.
Please help me find a working solution.
