Sub-20MHz channels are only configurable via debugfs and are not supported by LuCI or any of the standard Linux wireless utilities. Try echo 5 > /sys/kernel/debug/ieee80211/phy0/ath9k/chanbw on both sides of a working p-t-p link.
This actually improves your connections, bandwidth, speed, etc? is 5Ghz so used on all channels where you live ? Did you have problems with devices when you changed to 5/10Mhz band ? Which channel do you use?
It is really interesting to me this, where I live there almost no 5Ghz signals around. I am in typical very populated area city.
Moving to the 5Ghz band would be my suggestion too in a crowded 2.4Ghz area. A simple Dual band AC Lede compatible router could be found for under 20 USD.
Using half (10Mhz) or quarter channel bandwidth will give slower speeds, but might still work better due to less interference.
I could not find the references, but I think the 5 and 10Mhz bandwidth was dropped from the official ieee80211 specs.
I was using 5ghz, since about a year with no problems... I have a LOT of SSID's around with a lot of signal and almost no one have 5ghz. some ISP new routers but less than 10 and usually on same channels.
I have fast transmissions of multimedia from computer-tv just using wifi... works very well.
Because they are not in the International "unlicensed"/"licensed by regulation" portion of the 2.4. GHz band, hence inaccessible (that's the easy answer).
(Please note using a radio of of it's manufactured spec is illegal - I'm not considering the Amateur Licence, which the router can't guess you possess.)
I'm curious, does it work on channel 0?
Are you even able to set channels: -2, -1 and 0 on your OpenWrt device?
hi ,yes (it work on channel 0) . 0 is the only one that is up , sometimes not, and sometimes up and down until it goes down again.
I'm just curios to understand how it works.
also in luci channel -1 = 255 and channel -2 =254
hi, i found a way to make it work. but i don't like it. because after a reboot the channel switch to another one. anyway that how i did that, via command line.

hi lleachii, it work with every ath9k wlan, it work in mesh mode and monitor, but not in ap and station mode. i think we need touch hostapd to make it work in ap and station. anyway that was just for fun, long time now that i'm not playing with that.
you need patch mac80211.
if you need the patch i can share it.
