I read a WPA "Need-To-Know" article here: http://www.tomshardware.com/network/20030710/index.html
Definitely worth visiting ... 18 pages long though.
Some interesting items include:
------------- "WPA = 802.1X + EAP + TKIP + MIC"
------------- "And that puts [WPA-PSK] far ahead of WEP as far as I'm concerned, because it's so simple that people might actually use it!"
------------- "When I tried to get the Linksys WPC11v3 to talk to the Belkin AP with WPA-PSK enabled, the AP locked up, requiring a power cycle to reset it. "
------------- "Manufacturers are putting their primary WPA efforts behind their current-generation 802.11g and a/b/g products. "
"WPA upgrade support for older products is not guaranteed. Manufacturers' commitments to providing the upgrades vary widely, with timetables tending toward later rather than sooner."
------------- "In the short-term, if you want to avoid hassles and extra cost with WPA, your OS better be WinXP."
------------- "Client adapters have not required firmware upgrades and became WPA-capable by just upgrading their drivers using the normal Windows driver upgrade process."
------------- "No mixing allowed! It appears that the APs that I looked at don't support WEP and WPA- enabled clients simultaneously."
------------- "No AdHoc support. WPA currently supports Infrastructure mode only, with AdHoc mode support delayed until WPA2. The larger impact of this missing feature may be on wireless Ethernet bridges like the Linksys WET11 and WET54G, which perform some of their more useful tricks in AdHoc mode. "
------------- "Conclusion: "The good news is that, when it works, WPA is vastly more secure than WEP, and a hell of a lot easier to use, especially in the consumer-friendly Pre-Shared Key (WPA- PSK) mode.
"The bad is that if the present trend continues, many WLAN owners may have to abandon their older products and purchase all new goods in order to enjoy the benefits of WPA. "
