Tenbay t-mb5eu-v01 stupid problem -> resolved?

I had already had the problem with two Newifi-D2 boxes which had all identical MAC addresses for the two boxes and which did not even correspond to what was indicated on the label stuck on the box. It had been easy to find out

For the 3 * Tenbay boxes that I have there, it was more difficult to determine because the MAC addresses were correct except for the 5 Ghz WIFI where they were identical for the 3 boxes which did not allow them to work as MASTER <-> CLIENT with error #22

My bad solution only for test
back up mtd3 product partition
change the value of the WIFI MAC address
opkg install kmod-mtd-rw
Use the script that goes well
insmod mtd-rw.ko i_want_a_brick = 1
mtd write "mtd3 modified" factory

but possible not the manufacturer but or else the dts file does not read the correct values

There may be similar problems with boxes from other manufacturers because I have seen a lot of things precisely on this subject and with WDS

Run after modify dts file with this: .(mtd3 factory untouched):

&pcie {
	status = "okay";

&pcie1 {
	wifi@0,0 {
		compatible = "mediatek,mt76";
		reg = <0x0000 0 0 0 0>;
		mediatek,mtd-eeprom = <&factory 0x0000>;
		mtd-mac-address = <&factory 0x4>;
		nvmem-cells = <&macaddr_factory_4>;
		nvmem-cell-names = "mac-address";

I did this a bit at random by taking the dts code from a HUASIFEI mt7621_xwrt_wr1800k-ax-nand which does not have this problem.
I now have different MAC addresses and the AP <-> STA link works without error
