| + | Nothing's changed. I connected to cd:e4, and could ping the 3 south routers, but high packet loss. I SSHed into schefflers to reboot it, and | ||
| + | packet loss went down (though ping times were still highly variable). | ||
| + | |||
| + | Connecting to 4d:a5 (downstairs-north), I can ping the router, but nothing else. I sshed in and rebooted it; no change. | ||
| + | |||
| + | I got a ladder and plugged my laptop into the ethernet coming from the gateway router. I could ping it fine. | ||
| + | I powercycled the downstairs-north router, and everything came back up. | ||
| + | Argh! I don't know why it's working now. Was it a loose cable? Why did it start working when I physically unplugged and plugged, but didn't work when I rebooted from the commandline? | ||
| + | |||
| + | I dunno, but it's working now. | ||

| + | ====== Apr 24, 2014 ====== | ||
| + | The problem is that everything's showing as down besides the gateway router. | ||
| + | The gateway router is up and looks fine. It's got an Ethernet link to the downstairs-north router. | ||
| + | I can connect by wifi to the downstairs-north router, and SSH in. I couldn't ping anything else from it. | ||
| + | I rebooted it. No change. | ||
| + | |||
| + | I can connect to the wifi on the 0:23:69:b3:cd:e4 router. | ||
| + | I can ping mustachios, schefflers and downstairs-south, but the ping times are very long: 1-3 seconds. | ||
| + | I can't SSH into the mustachios router: the connection is rejected or times out. | ||
| + | I can ssh into the schefflers router. When I ping the mustachios router from there, the pingtimes are good. | ||
| + | |||
| + | I rebooted the Schefflers router and pingtimes suddenly got better. I guess that's what I was connected to. | ||
| + | (Is the wifi on the mustachios router down?) | ||
| + | |||
| + | When I ssh into schefflers, and ssh into mustachios from there, I can get in. | ||
| + | I guess the mustachios router is configured to not allow ssh from wifi. | ||
| + | |||
| + | Regardless: there's an obvious connectivity issue between schefflers and downstairs-north. | ||
| + | AND between downstairs-north and gateway. | ||

| Nesrin emailed a few days ago to say that the south part of the network was down. I checked remotely, and it seemed like the 86 router was offline. I finally had time today to go by. The router had been unplugged. It also suffered some trauma: one of the antennas is missing, connector and all. I plugged it back in and everything came back up. I got a stepladder by knocking on the door of the security office. The nice fellow there didn't know where to find one; I suggested the boiler room. There was, indeed, one there. | Nesrin emailed a few days ago to say that the south part of the network was down. I checked remotely, and it seemed like the 86 router was offline.
