Hi
I have Ubiquiti Nano-Bridge-m5 nb5g25 model, in my country they use mesh networks to access internet.
wireless regulations are not applied, so they use channels like 164/5820 Mhz and 133/5665Mhz
which is available in Ubiquiti Airos, but unfortunately it's not enabled in lede/openwrt and there's no easy way to enable them.
this is a screen shoot from my nanobridge station
also i have tp-link w8970 which is based on atheros AR9381 wifi card, in syslog i see that 5ghz band is disabled :

So is there any way to enable them, Do i need to patch ath.c or regd.c.
When i look at /etc/lib/firmware i see eeprom ath9k-eeprom-pci-0000:01:00.0.bin maybe i can enable 5ghz and change the country code?
Enabling 5 GHz in the TL-w8970's wifi chip will not work because though it may be a dual band chip, it's built as a single band router. The RF hardware between the chip and antennas can only work at 2.4.
Thank you very much. @mk24 tell me that my t-link will not work with 5ghz because the rf chip.
for now i just need channel 164 and 133 on 5ghz band for my nano bridge.
hi.
i didn't get success,it's need someone that have a knowledge with drivers and modding.
super channels= nonstandard wifi channels, some of them are used by ham radio, etc...
at least now i'm using a fiber connection using epon tech.
