I pretty sure I've read that all 802.11n routers slow approx. 20-25% mixed mode. You get right at (or slightly over) 100 Mb/s in 802.11n mode when using the 5 GHz band and 75-85 Mb/s in mixed 802.11/b/g/n mode. If I recall correctly the speed drop is caused by mixed mode requiring use of the old 2.4 GHz band. At 5 GHz the N routers are able to transform 2 channels into a single big data pipe, but if implemented at the 2.4 GHz band "channel bonding," as its called, interferes with bluetooth, which operates in the same band. Still 80Mb/s is pretty decent speed. snip I installed the Airport Card in my 500mhz dual USB iBook and it connected with my new NetGear RangeMax N router on the first try. And I have 100mg speed! And this is with a cable going out of the router to a switch and hard wire connecting to 3 Macs, a Dell and a network printer. As a matter of fact, the real reason I bought the NegGear N router was for my Toshiba laptop and I am still trying after 3 tries to get it connected. I will get it eventually. It takes time and patience in unhooking and rehooking all the connections in a specific order. I have to work for a living in the meantime.
