Source of the problem: commit b551660/lib/netifd/wireless/mac802.11sh Device problem occurs on: Netgear R7800, LinksysWRT1900ACSv2, Netgear EX6400, TP-Link Archer C60 Software versions of OpenWrt/LEDE: v19.07.3 and master
If I go into 'Network > Wireless' in LuCI and click the 'Restart' button on the 2.4 or 5GHz radio, that radio is the only radio that stays working, whereas the other radio says disabled and wireless not associated.
I can also replicate this via SSH/CLI running wifi up radio0 disables radio1. Running wifi up brings radio1 up this but drops radio0. If I run wifi up a second time both radios come back up.
My forum has been linked to a Netgear 7800 thread found here https://forum.openwrt.org/t/netgear-r7800-exploration-ipq8065-qca9984/285/2259 and there has been confirmation that there appears to be a problem with commit b551660 from May 4, 2020 for openwrt/package/kernel/mac80211/files/lib/netifd/wireless/mac80211.sh. Rolling back to commit 0495324 appears to fix this issue.
I too can confirm this by renaming mac80211.sh to mac80211.sh.old, downloading commit 0495324, placing it under /lib/netifd/wireless, setting the permissions to 0755 and then running wifi up radio0 in SSH/CLI. Radio0 (5GHz) drops as expected and after a couple of seconds it is back up all without affecting the radio1 (2.4GHz).

Steps to reproduce:
I created a post here https://forum.openwrt.org/t/wrt1900acsv2-only-one-wifi-radio-is-staying-up/64273 regarding the last WiFi client disconnecting from the AP stops working on that radio.
If I go into 'Network > Wireless' in LuCI and click the 'Restart' button on the 2.4 or 5GHz radio, that radio is the only radio that stays working, whereas the other radio says disabled and wireless not associated.
I can also replicate this via SSH/CLI running
wifi up radio0
disables radio1. Runningwifi up
brings radio1 up this but drops radio0. If I runwifi up
a second time both radios come back up.My forum has been linked to a Netgear 7800 thread found here https://forum.openwrt.org/t/netgear-r7800-exploration-ipq8065-qca9984/285/2259 and there has been confirmation that there appears to be a problem with commit
