Can the Airport Extreme run both 802.11n and g at the same time?

    I remember hearing something about it going down to 54Mbit/s if anyone connected via 802.11g, is that correct?

    I was considering replacing my Airport Express for the Extreme to get the speeds of 802.11n, but if it is so that a client connecting with g will lower the speeds for the other clients then there really isn't much point since my girlfriend will also be using it with her MacBook.

    It goes down to 130Mbps for n devices in mixed mode. g devices continue at 54mbps.

    That number is not a fact...it depends on how much the G devices are being used. As singe G devices take longer to transmit data they still uses up the air waves during that time. Which slows down N as it has to wait for the G device to finish talking. So the more you use the G device the slower the N device operates as it has less airtime.

    Yeah. Those are maximums in mixed mode. Real world throughput will obviously be lower.

    Would it get even worse if I used the original Airport card? (b, I think) My G4 iMac won't take g.

    What if I turn the old one off except when it's in active use?

    So my speeds would only go down when my girlfriend is using her MacBook then?

    If it is one of the original Macbooks then yes. They are only G. If it's a Core 2 Duo Macbook, you can update it (software) to N or even better, if it's a newer Core 2 Duo Macbook, it is already N.
