What's the proper way of setting channels (2g and 5g) from shell?
And saving the settings?

Been experimenting but not finding the correct way of doing it. What i'd like to do is to set country JP for 2g (to use ch 14) but BR for 5G (proper bands for my location). Or some other custom setup.

Seems someone had tried to do the same 2 country setup and failed. I was thinking more in terms of "wl" commands, how to set/choose channels directly.

Or some solution to get ALL possible channels into use (1-14, 36-165).

Interestingly "wl channel" reports:

channel Set the channel:
valid channels for 802.11b/g (2.4GHz band) are 1 through 14
valid channels for 802.11a (5 GHz band) are:
36, 40, 44, 48, 52, 56, 60, 64,
100, 104, 108, 112, 116,120, 124, 128, 132, 136, 140,
149, 153, 157, 161,
184, 188, 192, 196, 200, 204, 208, 212, 216

What are these 184-216 channels? Possible to use with consumer equipment?
 
This far country code X2 seems most promising with channels 1-13 and seemingly all channels between 36-165. Adjusting RSSI to -88 db there's still 6/6 Mbps connection in most difficult remote corner (signal below -80db!) with 5 GHz permitting me to escape using horribly congested 2 GHz bands. Which seems a much better solution than trying to invoke use of channel 14 (which i was unable to do).

When experimenting with wl commands and direct channel setting i manage to break N operation and router falls back to 54 Mbps.

Took a look at source but couldn't find where properties of cc X2 are actually set up.
