Can't change country on RT-N66U

[steve23094]

Hi,

I am running 3.0.0.4.374.38_2 Merlin firmware on a RT-N66U.

The 5Ghz band in my block is getting increasingly crowded. At the moment I can set the channel as 36,40, 44 and 48. I want to change to one of the higher channels which I understand are legal here in the UK. I believe I have to change my country to GB to access these higher bands.

Entering this:- nvram show | grep country_code into the Run CMD it tells me my country is set as EU.

Based on a post I found from Merlin I key this:-
nvram wl0_country_code=GB
nvram wl_country_code=GB
nvram wl0_country=GB
nvram wl1_country=GB
nvram wl1_country_code=GB
nvram regulation_domain=GB
nvram regulation_domain_5G=GB
nvram commit

Then running nvram show | grep country_code again it still shows EU.

Does anyone know what might be going wrong?

Thanks.

On mine running 374.38_2-em it shows:

wl0_country_code=GB
wl_country_code=EU
wl1_country_code=GB

After running those commands...

That's weird.

Can anyone confirm these are the correct commands?

Why is it not changing anything on my router but only changing some on richto's router?

Richto, can you access the higher 5Ghz channels?

nvram set pci/1/1/ccode=GB
nvram set pci/2/1/ccode=GB
nvram set wl0_country_code=GB
nvram set wl1_country_code=GB
nvram set regulation_domain=GB
nvram set regulation_domain_5G=GB

This is what works for me in the UK, flawlessly. It was posted by fellow forum member 'Gonzo' who should get the credit.

You can check the values by replacing 'set' with 'get'. Don't forget the commit command when done.

Cheers

That worked perfectly, I now have access to the higher channels.

Oh. And I added in nvram set wl_country_code=GB for good measure. No idea what it does, but it was previously set to EU.

Thanks DrT.
