Test ubiquiti UAP-AC-Lite, UAP-AC-LR and UAP-AC-Pro-Gen2 in IPv6 only networks

Description
Steps¶
- Upgraded firmware to version 4.3.13
- Configured them via unifi network
- Connect them to an IPv6 only network
Result¶
- Access point turn off the radio shortly after booting
- Tested via "wpa_cli -i wlan0 scan" on computers nearby
- This does not happen if the AP gets an IPv4 address via dhcp
Source of problem¶
It seems that the uplink-monitor fails to detect the IPv6 uplink and according to https://community.ui.com/questions/UniFi-Controller-Connectivity-Monitor/630191eb-b6a1-4354-898b-610211197414 if there is no uplink, the radios are disabled.
Further issues¶
- It seems /etc/resolv.conf is empty
- this might be, because rdnssd is not running
- Project changed from Open Infrastructure to ipv6
- Description updated (diff)
Debugging further:
ubnt-lr-1-BZ.v4.3.13# ps w | grep hostap

4392 ubnt 1228 S grep hostap

ubnt-lr-1-BZ.v4.3.13#
It has a record of an own ip, which it actually set it up.
In the log this message might be the reason why the radio is turned off:
