I have an OfficeExtend solution working with 20 or so AP's and a 5508 in the DMZ. I've recently had a couple AP's that I configured and tested over an internet connection, but when I sent them out to the users they don't join the WLC. In fact, the users go to the admin interface of their home router and the router doesn't even recognize that a device is there. The users can plug a PC into the same port on the router and get to the internet with no problem. The last one that had this issue was using a Netgear WNDR4500 home router and AT&T DSL. I know the AP worked before I sent it out and about 15 OEAP's are working on the controller fine so I believe it's a quirk with the home router and/or internet connection. Any advice?
