Unless something has changed, monitoring and control of Wireless Workbench cannot happen across subnets.
Your problem seems to be the subnet that your computer is set to. With the subnet set to 255.255.0.0, your computer will only be able to see devices that share the first two octets of your computer's IP address (10.14). If you were to set the subnet to 255.0.0.0, then your computer could see any network devices that have a "10" as the first octet...the rest of the IP address wouldn't matter. A better option would be to stick with the same subnet, but make your IP range for everything in Wireless Workbench 10.13.x.x
