Hi there I had a question that I couldn't find the answer to. At work I need to extend the wifi network throughout the shop. its a steel building approx. 300 feet long and is separated in the middle with a wall. similar to having 2 steel buildings beside each other. I currently am using a wrt3200acm at home and love it. fast and great range. I would like to use a pair of them at the shop. so 2 questions would be would using a second one as an access point provide seamless roaming and could I use the router that is configured as an access point to connect storage via usb 3.0 port.
