[conspire] WiFi adapter

[Tony Godshall]

Others have answered with good info, and I'll just pipe in
with an idea that might give you the "no external power"
requirement from the point of view of the system while
also giving you the powered hub that you need.  If the
lapdock's USB power out has enough power to run the
Pi and also the hub and all the peripherals you want to
run from it (you might want to read its specs), one could
theoretically tap into the USB cable from the lapdock to the Pi and
draw the +5V and ground to power the hub.  I'm not
saying *you* should do this- it might catch flame and
burn down your house and eat your dog, but it is
something I would probably try.

That said, you might try running this wifi

and see if it works.

they say "If using with a Raspberry Pi: ... You may find that you need
to have a powered hub to use this adapter, so if you're having power
flakiness with your Pi, try a hub! "

BTW- I've been buying USB peripherals for
Raspberry Pi and finding they work *great*
with other linux devices- way fewer driver
hassles.
