i'm looking a way to change permanently the mac address of my radio0 who is set as a client and connected as a wifi repeater. I tried to add option macaddr in the /etc/config/wireless, i also tried uci command, but nothing works.

Many times, a reboot is a quick way to make sure that settings "take", especially with things that are "up and running", such as networking. Changing the MAC address is a pretty low-level thing.
