Are you speaking of a TL WDR3600/4300?
can you make a very slim build? for use as a dumb ap? thanks
How does your lan switch configuration look like these days?
I've just pulled the snapshot and built a fresh openwrt, after reboot, the wired interfaces did not work. I was able to login via wireless, and figured that some changes with the switch config. Now I have wan working and temporary fix for lan only.
Might be worth looking at this:
Hi, error phyton "0.start_main.bat"

yes. not open .bat
download and install requirement files from here and try again it works for me on windows 10.
Error on open 0.start.main.bat, any help?
Traceback (most recent call last):
File "main/main.py", line 17, in <module>

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa0 in position 1: invalid start byte
.
what router you have? be aware you can use the scripts only when your router running official firmware .
install all requirement and try again.

Hey, sorry for the late reply I see that @bouzouste already added screenshots about MAC addresses.
Indeed, all MACs are located at "Factory" partition. For 1G version "Factory" partition has offset 0x50000 for 100m version it is 0x30000 so keep it in mind. I know that we are able to read "Firmware" partition from OpenWRT CLI using mtd utility, but I didn't have a chance to check if we are able to write it back to flash using mtd. I did it all using HW SPI flasher. SPI flasher can be built with an stm32 "blue pill" board - check this repo. Use your preferable way.
Let's get started.
MAC offsets from the start of "Factory" image are next(for 100m version):
- 0x0004 - WiFi 2.4G
- 0x8004 - WiFi 5G
- 0x0028 - Ethernet
As you can see(compare with @bouzouste's information), WiFi MACs locations are the same for 1G and 100m version.
Now let's change WiFi radiation power. But remember: DO NOT break your local law about allowable radio radiation power and bla-bla-bla - you know it 
.
Use the same "Firmware" partition and take a look at offset 0x00A0:
Starting with this offset you will need 14 bytes in a row.
Those values regulate maximum WiFi 2.4G radiation power, so replace all of them(14 bytes) with 0xFF.
Now go to offset 0x8060:
From this offset, you will need every fifth byte for 12 times.
Those values regulate maximum WiFi 5G radiation power, so replace all those 12 bytes with 0x7F.
Keep in mind that results values for 2.4G and 5G are different 0xFF and 0x7F respectively.
Happy WiFi radiating 
.

By the way: had someone a chance to make a dump of stock image for R4AC aka 100m version?

And here's a modified 5G power table (Gigabit version):
EDIT: After performing some testing, I saw decreased effective range and throughput after modifying the partition. It may be better to test some favourable reg domains instead.

Hi, could you please check the sha256 again?
I always get
55d55b7f4d291edee08d9c64638194b679a83100095a82be1cec6cabb737cde5
wherever i download/check the file. Your other builds match the checksum, just not this last one.
thanks

Yes, you're right about offset for 1G, I made typo. Correct offset 0x50000.
About power table you may be right. Those values just removes software limitation, so you can set higher radiation rate in the settings, and even it can really radiate more power. But maybe HW has some power limit after which it will produce much more noise. I don't have any RF tools to check all those stuff.

Hello. the problem is with where i upload it. i upload that file somewhere else and now sha256 should be OK .please go to below link and download it again. thank you very much

Perfect, now it matches the checksum. Thank you.
