The main box says there is a hardware problem but if I switch it all off unplug everything it works

Message says hardware problem on main box I disconnect everything then reconnect and it works fine. It also disconnects from my two mini boxes regularly and same process resolves this. 
I've removed the sleep function as I was advised previously and no different

Hi @Gran27 Try rebooting your router by removing the power cable for 30 sec then reconnect to reboot, then reboot your main SKYQ box by turning the power off at the socket for 30 sec then turn back on, then do the same with any Mini boxes?
