Dear OpenWrt gurus! Hello to you from Russia!
Help solve the problem with the width of the channels and the choice of the country. There is a MikroTik LHG5 device. In the stock firmware 5, 10, 20, 30, 40 MHz are available, as well as some frequencies that I cannot scan on the OpenWrt firmware. Please help with advice - in which direction to go. I am writing with the help of a translator. Sorry if with errors.
Model MikroTik RouterBOARD LHG 5nD
Architecture Atheros AR9344 rev 3
Firmware Version OpenWrt 18.06.1 r7258-5eb055306f / LuCI openwrt-18.06 branch (git-18.228.31946-f64b152)
