I (Gabe) got a call from the owner on my cellphone; he was getting the “Oops, can't connect to the Internet” page from wifidog. The auth server was reporting that the router had been down for over 5 days. I had him powercycle the router, and after a fairly long wait it came back up.
I (Gabe) went in today because they got a new POS system and called to ask for help. Their router didn't have openvpn on it, so couldn't be accessed remotely. Their local machines are plugged into a DLink router, into which the WT router is also connected. They needed a few ports on the DLink router forwarded to their POS system, which I did, and then gave them the password to the DLink. I also installed openvpn on the WT router.
