Wired Backhaul from an existing wifi router to a RBK750 satellite

[Bnichols907]

I have a remote building that I would like to get wifi in but I don't have another RBK750 satellite to put out there. Can I use my older wifi router and connect it with cat 6 to one of my RBK750 satellite's? If so anything special I would have to do?

Put this remote located router in to AP mode. 

How far is this remote location from the RBS?
