+Wifidog reported that the node is down.  I was able to ping it via OpenVPN ('ping 192.168.222.77' from the auth server), so I sshed in (ssh root@192.168.222.77' from the auth server), and ran 'wdctl status'.  It took a long time to run, and came back saying that the wifidog gateway doesn't have Internet connectivity.  When I've seen this in the past, it's been because the router doesn't have a valid DNS server.  Indeed, 'ping yahoo.com' returned nothing, but 'ping 4.2.2.2' did.  So I forced it to use the opendns servers, by:<code>
+nvram set lan_dns='208.67.222.222 208.67.220.220 4.2.2.2 128.100.100.128'
+nvram commit
+vi /tmp/resolv.conf
+</code>
+add these lines at the top:<code>
+nameserver 208.67.222.222
+nameserver 208.67.220.220
+</code>
+Immediately I was able to ping yahoo, so DNS started working.  Wifidog didn't pick up the change right away, so I restarted it ('wdctl stop', then '/etc/init.d/S65wifidog').  It came right up.

 Wifidog reported that the wifi went down last night sometime.  Gabe went by, and couldn't see the wifi network, but the router lights were on.  I restarted the router, and everything came back fine.
