Get your free wireless La Fonera Router
No idea if there's anyway you can get one for free otherwise but I just received an e-mail from aspiring wireless revolutionaries Fon stating that they're running a promotion in which you can receive their wireless La Fonera router for free! It normally costs $29.95, which is pretty cheap in of itself but free sounds so much better. So if you've signed up for a FON account, check your e-mail and pick up their free wireless router.
Why should you use it instead of your current wireless router? Because you can get paid for every person who pays to use your connection and you get free wireless access whenever you're near another Fon wireless hotspot. Fore more information, hit up their site
