I presently have one access point 1200 series that points to our Radius Server via EAP protocol for security. Every thing works great. The client wants to add additional AP throughout the building. I see you can do it via repeaters or using other AP in access point mode with non overlapping channels..I dont have a lot of experiecne with cisco but learn quickly. We have wired wall ports for all the devices, is it easy to extend and what would be the best document to follow. thanks
