London, USB wireless network adapter
 

I want to run Linux in a small wireless LAN environment with the connection speed of up to 20Mb/s. What is the best support network card and chipset that I can buy in London area?

Mac

...London, England, or London, Ontario, Canada?

Heh, London, England

Haha. :)

Well, while I don't know where you could pick up a serious piece of WiFi, I know you should be looking into the Wireless-N adapters. If you're going for a "cool" factor, the Linksys ones look the nicest; however, they also look like if you get too close, they will render you unable to procreate (hehehe). :)
