Went to nw4 to see if I could contact the new AP we installed yesterday, unw4ap. This is the one where I assigned it 192.168.1.27, which is also used by une3ap. I couldn't contact it, even over the management wifi, after temporarily disabling the management wifi of unw4. I configured unw4 to always connect with tv2 78:8a:20:ec:8f:1a.
Went to nw3, and verified that its ubiquiti is not connecting with nnw4ap. This could still be a problem with nnw4ap, but as a fallback I installed a cell modem at this site.
A modem with a Verizon sim would connect, the best I saw while hand rotating the directional antenna was 2-3 bars, 3G. Omnidirectional 1 foot whip gave about 1 bar. A modem with an ATT sim reported 3 bars, 4GLTE, so I used ATT. The directional antenna is pointing SW down the stream valley, at about 240 degrees. It is mounted on the TRH boom. One would need a longer RG-8 cable to go higher, but the signal seems good enough. Removed the bulkhead USB connector on the DSM and routed both the PWRMON USB and RG-8 cable through the hole. Needs plumbers putty or steel wool to keep critters out.
Was able to login while VPN'd to UCAR.
I hand edited /etc/network/interfaces:
allow-hotplug eth0 eth1
iface eth0 inet static
# gateway 192.168.1.1
# dns-nameservers 192.168.1.1
iface eth1 inet dhcp
