I had wifi since 2001 with a Apple Snow base station (did 802.11b)
I then had a Apple Airport 802.11g base station + Netgear .11g router
Now we have x2 Timecapsule's running on 802.11an under 1 network name (WPA2) and
x2 Airport Extreme Flat + x1 Airport Extreme Dome base stations under another network running WPA2
All connected to a ethernet network to a 24 port gigabit switch. I also have a Buffalo 802.11g base station with external antenna connecting to a friends house who has the same base station + antenna so he's connected to my network.
We have 4 mobile phones, x1 ipod Touch (my sisters), Wii, PS3, x3 Laptops, x1 Printer all using the wifi network.
What i love about apple's airport's are the fact you can manage them in a central location, the routers in them are pants but as base stations brilliant little things. I just wish they provided PoE and antennae socket on the new ones!!! :-(
