I got a second router, Netgear R7000P , but with any ddwrt version I get no 40 or 80mhz , even though I configured it like that.

On stock-firmware I get 80mhz and on my other router Netgear R7800 I also get 80mhz...but on this R7000P it is not working. (same settings)

Can this be fixed?

R7000P is broadcom based

broadcom routers have some limitations, e.g. not all channels are displayed and the extension channels are reversed

(you also have to follow some kind of order, select the extension channel first and then the primary wlan-channel - if i remember correctly)

and the build threads are not for general help requests

i would suggest you post your question in the broadcom forum

with enough information, like settings / screenshots

I split off the posts and moved to the right forum.

are checking immediately after a nvram erase ?

if so, reboot the router.

you should get 4 40 width & 4 80 width channels.

the low channels are missing because broadcom isn't dev friendly

Maybe it is also dependant on build?

Or on country setting?

Unfortunately the OP gives very little information like build number, settings etc.

Definitely need to know firmware revision number. I am not seeing this issue on mine. Router Database strikes again?
