Thanks for your time. Having spent many hours on the phone to Apple Care they've concluded my D-Link DSL-320T modem doesn't work with the new Airport Extreme Base station (2.4 + 5.0 GHz Dual Band model). I desperately need some advice or recommendations for a new modem. Apple care recommended the ADSL Nation X-Modem M3 This is still in supply directly from the manufacturer but many retailers don't supply it anymore. Interesting Apple stores used to stock it up until Nov 07? You thoughts are greatly appreciated. Best wishes.
