So the whole network falls back to b/g. i.e. a max of 54 Mbit/s for g or 11 Mbit/s for b (careful if you are comparing Mbits to Mbytes too).I believe they are on b/g
True-ish, but:actually depending on router and such he can have a mix and still get n speeds with g on the network its called dual band my time capsule is dual band i can have g and n at the same time on the same frequency which i do but i also have the 2.4 abg/n and the 5 abgn which a lot of the older devices dont use
My understanding of how the Time Capsule implements "simultaneous dual band" is that it has separate radios for the 2.4 GHz and 5 GHz bands. You can dedicate the 5 GHz for 802.11n and run b/g/n at 2.4 GHz simultaneously. Many other 802.11n routers are dual band, including other Airport and Time Capsules, but they have to pick one or the other.I'm using the basic router that Verizon fios installed; could that be it?
