Work Around You can choose another channel like 40, 44, 48, 52, 56, 60 or 64, and Channel 36 will be covered due to the width anyway. Same goes for 149 as you can choose higher or lower and still cover channel 149 if it is allowed for your country.

Thanks David, I tried again all the channels, but no luck. As soon as is set to 160Mhz, the adapter gets disabled or tx power off. Probably because the power table/regulatory.db. If you change country and it does not match what has in eeprom, will get disabled. If upload another regulatory.db where I modified, the kernel does says "invalid reg domain". It checks something somewhere. The problem is how this is handled by Marvell... since last year we are allowed to use ch 36 at 160Mhz and 30db, but the reg table is stuck at 80Mhz and 23db.

On a side note, poking around that bin file, I found two interesting strings. it seems there is a "party mode" coded into it

That’s a Die Hard reference, and I’m sure just a programming joke.

Mwlwifi does not touch regulatory domain.
