But no idea what is going wrong.

Does it work with LEDE 17.04?

I might have spotted an unintended change in https://git.openwrt.org/f3bdc4a76aa2.

Would you please try an image from https://www.kresin.me/files/ar71xx-nand/.

This could be related to task_id=1607 same problem but for Nighthawk X6 R8000

I tried the link suggested https://www.kresin.me/files/ar71xx-nand/

Did a sysupgrade of the R6100, still no 5Ghz. Removed /etc/config/wireless and rebooted (this rebuilds the file). Still no 5 Ghz. Here's the contents of the rebuilt file:

config wifi-device 'radio0'
option type 'mac80211'
option channel '11'
option hwmode '11g'
option path 'platform/ar934x_wmac'
option htmode 'HT20'
option disabled '1'

config wifi-iface 'default_radio0'
option device 'radio0'
option network 'lan'
option mode 'ap'
option ssid 'OpenWrt'
option encryption 'none'

Yes, both 2.4 and 5 Ghz radios work as expected (come up, are visable in LuCI, pass traffic) on the R6100 with v17.01.4

Any update on this issue?

The 5Ghz works fine in 17.01.4, but is NOT working in any later release, including 19.07.0.
