    Is there any utility or config screen for the MBP that I can use to empirically determine whether I'm connecting at 802.11a, b, g or n?

    My router doesn't report the connection type of the clients.

    And for the typical DSL modem/Router/wifi unit, does it only operate at ONE speed - the SLOWEST that ANY connected client can handle; e.g. with 3 802.11g Macs and 1 802.11b PC, the entire WiFi network will slow to 802.11b?

    Thanks! :)

    Best not to use 802.11x in your title, as it's actually a separate standard from b/g/n used for authentication.
    Have you tried using network utility (found in the utilities folder)? It won't say specifically which one you're using but you should be able to tell from the link speed, i.e. 11 MBit/s for b, 54 for g, and higher for g+ or n.
    It's supposed to connect at the lowest common speed, but I have a D-Link n router, and I get link speeds of 130MBit/s even when there's a g device on the network (in this case, my iPhone)
