I'm trying to investigate poor wireless performance, which was described by @sanitariu
The thing I noticed here is that the EEPROM address was not defined, so it uses default value from mt7628an.dtsi, which is wrong for this hardware:
mediatek,mtd-eeprom = <&factory 0x0000>;
Real EEPROM is located in radio partition, so we must declare this:

&spi0 {
...
	m25p80@0 {
...
		radio: partition@07f0000 {
...
&wmac {
...
	mediatek,mtd-eeprom = <&radio 0x0000>;
};

But performance is still bad though.

Did you make some patch for the correct eeprom ?

You are the author of this https://raxp.ru/index.php/2017/06/21/lede-for-wr841n-v13wr840n-v4-ru/ ?
Can share the developments?

please use the existing pad-extra instead of your custom prepend-to.

I'm afraid it's not possible.
KERNEL_DTB = kernel-bin | patch-dtb | lzma
Calling pad-extra before making KERNEL_DTB causes, that all leading zeroes crated by pad-extra are subject of lzma a will be comprimed:(
I can't find better/simpler solution.
