I have a remote controlled system that uses a mobile broadband router, occasionally it has needed a reboot, which is a job that could be done automatically saving me driving to reset it...
There have been one or two Raspberry Pi projects that turn off a relay for a few seconds if a return ping to an internet address fails. There are also Chinese internet watchdog units, such as eBay.co.uk item 296195240193, that might be cheaper than buying a Pi, but lack details and have a general "toy shop" look about them.
It seems like such a common requirement that others must have done this before, yet such projects seem scarce... Any pointers and ideas, other than using a clock timer to turn it off twice a day?
Thanks
