I have downloaded the most recent driver for the 1470 wireless card utility from the Dell site and the WPA2 file you pointed me to. I still don't get the WPA2 option on the dropdown menu, only WPA (and some others). Under the Information tab on the configuration utility, I see 4.10.73.3 and a date of Dec. 16, 2005 for Software Version and Supplicant Version. The Driver Version is 4.10.40.0 with a date of Nov. 2, 2005. Does that sound right? Thank you again.

Yes, the Windows XP configuration utility shows WPA2 (WPA2-PSK). The options on the laptop's configuration utility for WPA2-PSK are AEP and TKIP. For the router, I also see two options for WPA2-Personal, AES and AES+TKIP. Should I choice TKIP for the card and TKIP+AES for the router? Thanks.

Just check the adapter's documentation; it doesn't mention WPA2.

Try switching to Windows XP Wireless Zero Configuration to manage your connection.  If your driver supports WPA2, it will show as an option under Data Encryption when configuring a connection manually.

OK, I'm all set up! Got WPA2-Personal running with AES encryption. Thanks so much for your assistance, Esquire, you've been a huge help.
