Improved internet bridge / Better range.

I live in a property with 3 floors + a basement and my networking setup is on the top floor Attic and find devices in living room and basement disconnect from the tado bridge. I have Philips hue and everything works flawlessly throughout. The capabilities of the Tado Bridge needs to be improved for longer wireless range or the devices need to support some sort of WiFi extending so they piggy back off eachother for larger properties. Shouldn't have to use powerline adapters as suggested.
