According to the definitions of Wi-Fi that I am getting, it sounds like my Linksys wireless ethernet card for my laptop is pretty much the same thing as Wi-Fi. It's a 2.4 GHz, 802.11b Notebook adapter. It does dot say Wi-Fi or W-Fi compliant, but I've read that it, indeed, is. (I didn't get the info from Linksys or Cisco Systems... perhaps I should.)
I've only used the card on my laptop when I've had my wireless router being used as my home network router (doesn't always work, probably just due to some settings that I can't figure out).
So, is this card really a Wi-Fi card that I can use on the road?
I will check out Linksys' site, too... but sometimes you guys react faster (I'm on my way to work, and the other tech usually hogs the computer that has the internet connection).
