Switch to Bell Ultra High Speed wireless and they give you the whole kit...well give might not be the right word.
or
go to a computer shop, by a linksys system and the experts there will also give you what you need for wifi capability in your computers, if it isn't already there. Most newer computers put wifi in at the factory.
If you are changing your Bell account...make sure you can port your sympatico e-mail address first...if not and believe me I just went through this, you loose your existing sympatico address for 180 days.
