Using this script you can reboot your Hitron CGN3 router via command line. Rogers in Canada sold this router as Rogers Rocket CGN3 cable modem/router.
You need cURL and bash. Edit the script if you have a non-default router IP, username or password. Just execute the script and the router should reboot.
Even after several software upgrades this routers keeps crapping. The symptoms are very high packet loss and the connection seems slow. A simple reboot always fixes the problem for me. I just run this script via cron every night to refresh the router daily.
