I have been enduring constant problems with a Netgear router and Netgear extender of various forms. The ONLY reason i endure the terrible netgear product is that Apple has completely missed the boat on dynamic DNS.
Unlike the suggestion above that its easy to use a OSX based client service (which is what i use with an AE base station at my home), this is NOT possible to use reliably at a second home where there are power outages while i am away. I need to rely on the automatic reboot of the router after a power failure to enable reporting to DYNDNS so that i can access my home automation system, video monitoring and temperature services.
I love all my super easy connectivities of my AE, AX, ATV's with my iMac, kids latpops, several iPads and of course iphones and yamaha reciever, and .....at my main home, utilizing my iMac with DYNDNS for remote access to files etc.
With the netgear router and extedner at my second home, i have to have two networks ( Main and Main_EXT) and switch between them, my AX for music to the home stereo gets dropped in airplay constantly and the Netgear extender will frequently just lose internet connectivty with the main router or while streaming DISH programming through my iPad to an ATV on a "spot" basis, just enough to interrupt the show.
Hours and Hours have been spent trying to get the netgear system to work reliabily as the backbone of my wireless system with only mixed success.
ALL BECAUSE APPLE HAS THEIR HEAD IN THE SAND ON DYNAMIC DNS AND THE NEWEST AIRPORT UTILITIES...
Come on apple.....I'll buy a new one asap if i knew it had this simple option, which EVERY OTHER ROUTER on the market has now.
