oh ok, may have to take a look,thanks. as i say i’m already convinced that a tp-link load balancing router would handle the connection bonding, but all the videos i’ve seen they are using said router to bond adsl through seperate ethernet. my idea was to tether the sim travel routers to each of my mango boxes usb ports and plug them into each of the tp-links wan ports. Maybe thats not quite correct though,i dunno
