Is there a way to alter the transmit power database?
My device (Archer C7) is capable of doing 30dbm max on 5GHz but I need to change to a specific channel and regulatory domain.

If remember correctly there was a "hack" in the past (though it was for OpenWrt I think) that would let you alter it yourself.

Any help is appreciated.

no that is radio design max, & firmware max. reg domains & channels arent special..

canada channel 5 @ 20dbm is the same as japan channel 5 @ 20dbm etc. just use one that allows 30 dbm for the wanted channel. 149+ allow it, 100+ is allowed on 1 reg domain we have, nothing does it below channel 100.

Ok, thanks for the reply.
What reg domain allows 30dmb on channel 100?

[tatsuya46]

macau, but limits 2.4ghz to 23dbm. as both bands have to use the same reg domain.

country MO: DFS-FCC
(2402 - 2482 @ 40), (23)
(5170 - 5250 @ 80), (23), AUTO-BW
(5250 - 5330 @ 80), (23), DFS, AUTO-BW
(5490 - 5730 @ 160), (30), DFS
(5735 - 5835 @ 80), (30)

Cool! Thanks.
I'll use that one than.

23dBm on 2.4GHz is fine The Archer C7 can't do much more than that I guess.

I have 2 Archers.
Archer 1st floor: 2.4GHz on channel 11 + lower (23dBm) and 5GHz on channel 100 + upper (30dBm).

Archer 3rd floor: 2.4GHz on channel 1 + upper (23dBm) and 5GHz on channel 108 + upper (30dBm).

Both are setup with country code MO (Macau).
