Unfortunately unusable. After a lot of trial and error. Neither the mobile phone nor the laptop or Macbook switches to the stronger signal. Whether Mac or Windoof. I now have 2x2 identical Wlan, visible in the Finder, but the weaker signals are always connected from the original WLAN box. So now I would have to give two different names and manually switch to the extended WLAN, as no device does this automatically... whatever the point of this is supposed to be.
