Windows 7 workon WEP but WPA

[guest]

Q: I'm having a problem connecting to my home wireless network using anything other than the WEP security protocol (win7rc, build 7100). The card is a Dlink Airplus DWL-650+ Wireless Cardbus Adapter using the latest available drivers (4.15.5.1). Ran fine using WPA-Personal/TKIP security protocol under Win XP, but can't for the life of me get it to work using Win 7 RC. All other wireless devices running XP or Vista are working as normal. I realize this is an older wireless card and would be OK if it doesn't work in the final release of Win 7, just wanted to report the issue.

When attempting to connect to the wireless network when the wifi router is configured as WPA, the wireless network on the pc lists the network name as a WEP 802.11g network. When manually configuring a wireless profile for the WPA network, the wireless network list shows the network as a WPA-PSK 802.11g network, but will not connect due to the "computer is not configured properly for this network" (or a message very similar to this). The configuration is exactly the same as the other working wireless devices, so I'm a bit confused as to why this message appears. If I configure the wireless router for WEP, the computer shows the network and clicking it pops up a dialog box allowing me to configure the pc with the network key and connect to the network automatically. <BTW, this is a really nice feature! Good going Win 7 network team!> I've tried different keys, yet to no avail. WPA no connect, WEP connects fine.

I'd like to maintain the WPA security for my wifi network, in the meantime, this laptop gets a hardwired and less-than-mobile setup in the house. If anyone has any idears, I'd be greatful.

Resolution: try different NIC or install latest driver.
