I just purchased two eap225 outdoor units and tried to get them setup today, using the software controller running on my laptop.  I was able to get both units configured and working in the same room.  I also updated the firmware on both to 5.0.5.  My situation is that I have two buildings and I'm trying to extend my network to the second building.  It's ~250 ft away, with pretty clear line of sight.  There's almost no other wireless networks in range , so congestion shouldn't be an issue.  I placed the LAN connected eap225 right inside a window facing the second building and moved the wireless eap225 to the other building, in a window facing the first.  When I view the devices in the software controller, it shows the eap in the other building as either disconnected or isolated.  If it's isolated, I can go under mesh and try to re-link it, but its not successful.  Is there anything I can do to help these two reliably link or is 250ft just too far for the eap225 outdoor?  

Thanks
