Custom Channel Bandwidth

Frequently asked, especially by those coming from a world with non-standard, vendor-proprietary hardware.

5 Mhz bandwith option?

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.
