Even though I don’t have any new 802.11n devices, I was eager to replace my aging D-Link 802.11g base station with a new Apple Airport Extreme base station. I had heard that the new antenna, as well as the new 802.11n protocol, would give me increased speeds with all devices, not just 802.11n ones.
After connecting everything and replacing my D-Link hub, I’m proud to say that I am very happy with the new Airport Extreme. The increased signal strength was not exaggerated, as most of my devices increased their reception at least 40%. Some increased 50%. I have an all cement loft, so my signal tends to degrade rapidly the further the device is from the base station.
