Re: Getting 50Mb wirelessly.
Actually it's worse than that. You need more than 5 channel spacing to clear completely, actually closer to 11.

You need 5 channel spacing to clear the bandwidth intentionally used/transmitted by the device but in fact bleed-off past the edges of this range cause interference far further than that. Running a single "big" device in 2.4Ghz "occupies" half the band but causes interference through the *entire* band, all the way through to channel 13.

And as for the N specification - WiFi certification actually requires all devices to be shipped - and default to - having "big" channels disabled in the 2.4Ghz band, and the specification also requires/requests (I'm not sure) the device to automatically turn it off when it detects other devices using the secondary channel. Frankly I think that's the best compromise and far better than disabling it completely (even for users in completely isolated/controlled environments).
