I’m seeing some strange networking issues. On a couple of occasions, I’ve lost communication to the remote station.
Currently, the remote station is sitting on the bench, and the RUT-951 router is connected to my home LAN via Wi-Fi. This is also the desired final situation.
On one occasion, the Pi and Windows PC lost comms to the Internet, even though I could access them remotely using
Microsoft Remote Desktop respectively.
The only interpretation is that the router lost its default route (which is to the home LAN’s gateway).
However, running the
route command on the router showed the proper routing table. All very odd.
The most likely cause is that I had the router sitting on top of the 12v PSU. I’ve moved it now.
Luckily, one of my reasons for choosing this router now comes to the fore. Being a router designed for remote installation, it has services built in that enable it to recover from some problems:
- One is a service to
pinga defined IP address (in my case
18.104.22.168) and reboot if a pre-determined number of attempts fail to get a response.
- The second is that you can set the router to reboot on a schedule.
I have now enabled both services, with the router rebooting at 3AM.
