    Almost certainly local Wifi contention issues as every BT modem in the
    street fights for control over channel 11. ISTR they have improved the
    default settings to avoid this but I don't know when.
    Look for neighbouring Wifi networks on the same channel and try to pick
    a channel that is cleaner or on the less commonly used 5GHz band.

    See my related posts on uk.comp.sys.mac comparing measurements with
    Ookla speedtest.net in different devices; iPhones 4S and 5S, Macboook,
    and Win 7 laptop, where iPhones are only 10% of the speed of the others.

    No really. WiFi connection speeds can vary for a host of reasons -
    signal strength variations in different locations, being connected to a
    different hot spot from the one you *think* you're connected to,
    contention with neighbours using the same channel, etc.

    I would want to start by seeing the results when the same laptop is
    connected to each of the two routers in turn, using ethernet. That
    should show the best that is possible. *Then* you can start mucking
    about with changing WiFi channels, using different locations, etc. in
    order to get a close as possible to the ethernet-connected values.

  4. Disconnect all wireless devices (switch wireless off at the hub is
    probably simplest) and connect *one* computer by ethernet cable to get
    an accurate speed test of the internet connection itself.

    If you get anything less under other circumstances it's a local issue
    on your home network, either the quality of the wireless connection to
    the particular device you're using, or the fact that another device is
    using some of the available bandwidth (perhaps an automatic update or
    a cloud synchronisation) while you're doing the speed test.

  5. I'm guessing, but could your son's laptop be using 5GHz, and yours 2.4 -
    and there's lots of contention for the 2.4 band at his house?

  6. It does.
    No, it doesn't.

  7. I suspect your laptop also doesn't support 5, but his does.

    It's a good job we aren't applying strict Boolian logic to this
