My family member lives rurally without a solid, speedy internet connection. They have both a satellite connection and a (rather slow) DSL connection. If I install a load sharing/balancing router, how will the slow ping of the satellite and fast ping of the DSL affect real-time events like video chat? Would the router (TP-LINK TL-R470T+) sync the timing to keep the connection consistent? I am totally new to the concept of dual WAN routers, so any input would be helpful.
