DUDE, did you not here that COMPUSA let go of half their company. Not that I would know about it mind you ;-)
BTW Wireless is a generic term for most wireless products. Wi-Fi typically refers to Wireless-Fidelity Network standards set for by the
WI-FI Alliance. Thus a wi-fi card with g or n capabilities should work on either or.... Two places that I learned about the technology was,
howstuffworks.com and smallnetbuilder.com via the link from tomshardware.com
You'll also want to check wikipedia's article, but be worned that not all knowledge their is accurate as wikipedia is a user input based
ecyclopedia for the net. Ergo , anyone may post there.http://en.wikipedia.org/wiki/Wi-Fi
As far as Wireless N, it's currently worth it for Gamers and small Business users until municipal wi-fi picks up some movement.
You'll want to make sure that your wireless N sales to customers are based on the latest DRAFT N. Draft, because the standard itself
has not been widely adopted due to patent infringement with the technology. The latest Draft N is nearly the real thing however.
Currently D-Link, Linksys, and Netgear provide the best 802.11n technology in performance. Linksys and Netgear I would argue provide the best security implementations. Buffalo Technology also Offers a router near the top of performance. See the smallnetbuilder.com site.
Any other questions?
