auto-reconnect feature for powerline comms ethernet bridge

Hi,

Simple question - does anyone have recommendations for a powerline comms (ethernet bridge) device that will automatically check its own connection and if it is lost (not due to unplugging the device but transients or whatever making the ethernet connection drop) to re-establish it? Or is there a device that "just works" and doesn't need power cycling to re-establish a data connection?

Thanks, John
