PC World investigates whether WPA labeling matches WPA certification: Sean Captain discovers that even when a product says it has WPA, you might need to check twice. Microsoft's now-discounted 802.11g router said on the box that it had WPA certification, but that's not the case. The device slipped in under the wire for Wi-Fi certification requiring WPA late last year, and the upgrade for WPA isn't due until this month. The Wi-Fi Alliance's database of certification had the correct details, however. Captain warns that if you need WPA, make sure the device has it: just being 802.11g isn't enough.
