    Can Airport Extreme run "n" and "b/g" at the same time? The reason I ask is that my iMac has n capability but my Dell laptop is only a b or g. I can't remember which one.

    I didn't think the express had wireless N? Did you mean Extreme?

    Yes and no. You can put it in b/g mode, but then you're not getting anything out of having an n router.

    You'll get the speed of the slowest device on all devices.

    That's not true.

    When you run the Airport Extreme in "Mixed Mode", you get 130Mb/s for N (as opposed to 300Mb/s for N only) and 54Mb/s for G.

    Really? I'm not trying to question your statement, but do you have any citation? I honestly thought that whatever the slowest device active was is the speed everything else takes.

    The wireless N device will connect at 130Mbps but the transmission rate will be limited to a/b speeds if there a/b devices transmitting on the network. If your a/b device transmits often the N device will operate as an a/b device.

    So if you are connecting something that doesen't send data constantly or only connects periodically (iPod touch say) you will see N speeds most of the time. If you are connecting a windows machine as a/b the netbios requests alone will degrade the network to a/b speeds.
