    I have an airport extreme set up with a wireless network running on N 5ghz. I do not own the newer model which can broadcast both N and G at the same time.

    I also have 2 airport express systems set up to extend this network.

    Somehow, my flatmates laptop, which only supports 802.11abg can see the network and even connect!

    What is going on?

    There is one other G router in the building which is for our internet, which is wired by ethernet to one of the express.

    802.11a is 54Gbps wireless, but at 5GHz ... so, your roommate does have a 5GHz compatible card, hence he will be able to see your AEBS.

    I've found that even if the AEBS is set to n-only 5GHz that an n-capable express will extend the network in a mixed a/n mode.

    Same thing goes for an n-only 2.4GHz network with the same equipment. THe AX will extend in mixed b/g/n mode.
