According to Transat - K1Box, along with Khub and Powerline adapters is $240.
I guess you need powerline adapters unless you are prepared to run an Ehternet cable all the way to your router or is there any other solution that is less expensive?
About 30 ft but in different rooms. I Isn't the K1hub the ethernet adapter that is connected by RS232C to K1Box and has ethernet port on the other end to conncect to router?
