Hi 

I have been running this System for a few years in our 2 story houe (1000 SF + basement) without any issues.

Right now we are almose done building a 32x60 pole barn, that will be fully insulated and split into a garage/shop area.   I tried moving the basement y the mandoor and it does get signal, but it is poor (1 bar with the door closed).  

So my problem is the metal walls and doors of the pole barn, I have metal on the outside, spray foam and them metal on the inside.  I am thinking at this point would be to run some CAT6 from the main Access point to the new building, but can I plug that into one of the secondaty acces points and keep on the same wireless network?   Or is there a better solution?

Thanks

Paul
