If you happen to find yourself in Paris this September 20th and 21st, cancel all other plans, buy a copy of the newspaper, pack a good book, and prepare to stand in line for several hours.

The French have embraced wireless wholeheartedly, but, unlike Americans, they are much more diligent about password protecting their wireless networks. This, of course, makes joining a wireless network and mooching off of someone considerably harder (free internet in hostels is not a guarantee, and can often be quite pricey).
