I am interested in setting up a repeated wireless network using an 851w and an 1121. The documentation for the 1121 specifically discusses repeater mode. The 851w documentation doesn't specifiaclly talk about repeater mode but it does have the command station-role [root, repeater]. Will these devices work together in repeater mode?
Also, what are the likely complications of having a client that does not support Aironet extensions? Is Aironet extensions the same as CCX? If so, what version of CCX is required?
