We work a lot with 3G Modems and rb411. Sometimes, the modem gets hung-up. A watchdog script will reboot the router but the modem is still Hung-up. The only way to overcome this is to cut the power to the router and then power it up again.
Is there a way to cut the power to the USB ports on the rb411? That way I can reset the modem and not the router and also, I will not need to get physically to the router.
