+On Nov 5 both wifidog and open-mesh reported that the routers at DGP were down.  Gabe contacted the folks at the park via email, and they confirmed that while they were moving the computer, they ran into equipment trouble.  The power supply for the wimax modem broke again, and Rogers refused to replace it (instead offering to sell them a new modem for $100), so they got a new power supply (at Active Surplus?).  In the process, the wired router stopped working.  I went by today to check it out.  It looks like the (5V) USR wired router died, perhaps because the (12V) Linksys power supply had been plugged into it.  I plugged the modem into the Linksys router, whitelisted the rinkhouse Dell workstation and the open-mesh gateway router in /etc/wifidog.conf, and now things are working.  The USR router has been pitched.  Gabe will pick up a new wired router sometime soon and come back to plug it in.

+The mesh network at DGP went down a couple of days ago.  I emailed staff to ask them to powercycle the rinkhouse router, but the network didn't come back up, so I went by to take a look.  There was no signal outside the rinkhouse.  I powercycled the router, and it didn't come up.  I got a ladder to take a look at the router, and the LEDs weren't on.  I took the router down and plugged it directly into the powersupply and the lights came on.  So I think the problem is one of:
+) The ethernet run from the kitchen (where the power supply is) to the rinkhouse router is damaged.
+) The PoE injector is faulty.
+) The internal PoE splitter inside the router is faulty.
+It's almost certainly the Ethernet cable.  I didn't have a spare patch cable to test with.  I think we should just go back with a patch cable and a length of cable and a crimper -- test with the patch cable, and assuming it works just right away run a new Ethernet line.  Bring lots of cable clips, and a hammer drill -- if the cable is secure in more places, it's less likely to be damaged from strain.  I think.

 Wifidog and Open-mesh started reporting that the DGP nodes were down again starting a few weeks ago.  (The network ran for about a week after the outage which ended July 19.)  Eventually the folks at the park identified that the modem was the problem.  They called the ISP and had them reassign the service to another router, which also didn't work.  Gabe went in a few days ago to test both modems, knowing that the power supplies flake out frequently.  Of the two modems and two power supplies they had, one of each worked.  But it wasn't the modem that had the service associated with it.
