correctly?

You still get a nice performance boost with 802.11b/g/n in 2.4 range even at 20mhz, but if you go to 40mhz, you'll be splattering all over the entire 2.4 band.

This is why all of the pre-N performance enhancements for G were troublemakers if you had multiple wireless networks in the same area. You turn it on, and one of two things happen - you either wreck performance of everyone else on that band, or everyone else wrecks your performance.
