This morning our RV345 suddenly stopped working: the music streaming from our Chromecast stopped and the traceroute to any address from the devices connected to the RV345 couldn't get past the first hop. The internet was normally working from the DSL modem connected at WAN1.
I tried to turn off the RV345, wait a minute, and turn it back on: the leds apparently completed the start-up cycle but nothing changed. I tried to ping the RV345's IP address and it replied normally, but the traceroute to any address still couldn't get past the first hop. The web configuration interface that is normally accessible on the RV345's IP address didn't work (the browser reported a connection timeout).
So I long pressed the reset button on the RV345, waited for it to reboot and it was then possible to connect to the web interface. I restored my previous configuration and everything seems to be working again.
What could have happened?
Thanks
