Will the wireless work through walls?

Hi,

Just considering if I should take the plunge and buy a solar PV package. But my consumer unit/fusebox is in my garage, so the wireless would need to go through an outside then two more internal walls before it reaches the lounge. I know that wireless networking has problems with that. Is the range of the wireless better than that ? just concerned as to if it would work.

Any advice would be appreciated, alternative would be to use a wired network link to the Emontx

 

Regards

Dave
