No, unfortunately I cannot. It depends to much upon which WiFi router you are currently using, which WiFi device you are going to use to extend the WiFi-range, which settings you are using, and what the network requirements your WiFi devices like sensors etc have. So you have to be an IT and network specialist to get it all working. However, nobody wants to tell you 
, promoting the idea it is all very simple.
However, ip networks are designed to offer transparant ip communication. So just give it try.
By the way, I use a Fritzbox 7590 router and a FRITZ!WLAN Repeater 1750E, configured as meshed network. I don’t have WiFi devices yet to connect to Homey. So far, I have no ip network problems.
