I have some systems fitted to vehicles which I have remote monitoring on, however this has proven to be really unreliable, I have to keep returning to these vehicles and powering down the venus, upon powering up it then reconnects to the net work and monitoring begins again. It is definetely the venus and not the GSM as powering this on and off has no effect.
Any ideas on what to do as these vehicles are spread accross the country and its a real pain to keep chasing them
