Does WPA and WPA2 wireless encryption work on Vista?

Guest

I have Vista Home Premium with SP1 and all the updates installed. I
have a MSI PC60G wireless adapter, with the latest driver, and it is
unable to connect to my Linksys WRT54GL router with WPA or WPA2. I
know that the router is working fine, because I can use an XP laptop
to connect to the router using WPA or WPA2. But with the Vista
machine, it always shows a "The wireless network security key is not
correct" when I use the diagnose option to see why it doesn't connect
using WPA/AES or WPA/TKIP or WPA2/AES or WPA2/TKIP. Vista can tell
that the network is there, as it shows the network name with 5 green
bars in the wireless connection window. It can also tell when I have
changed the security settings on the router, as it will say "The
settings saved on this computer for the network do not match the
requirements of the network." But it just won't connect to the router
using WPA or WPA2 for some reason. If I configure the router with
WEP, then Vista connects fine, but I want to use WPA or WPA2.

Can someone please confirm that wireless connections using WPA and
WPA2 are working in Vista? If so, then it must be a problem with the
PC60G wireless adapter. The PC60G uses a Ralink RT2561 chip, and I
have the latest driver installed for that. I even tried the latest
MSI driver, which is older than the latest Ralink driver, and that
still did not work. MSI says that the PC60G supports both Vista and
WPA2, but something is not working here.

They both work with Vista.
1. Update your router's firmware at the Manufacturer's website, so it is
fully vista compatible
2. Get the latest Drivers for your Network Adaptor.

I had a laptop working fine using Vista Business with WPA2 Personal and
TKIP+AES. I blew off Vista to go back to XP for various other reasons.

We use WPA-PSK/TKIP with XP, Vista and Linux.

The router works with XP and WPA/WPA2 (I tested that), so it should
work with Vista, since the router wouldn't know what OS the clients
are running. I also saw someone saying they are using Vista with WPA2
and a WRT54GL. But I can try upgrading to the latest firmware later.

Yes, I tried that and they still don't work.

What firewall software, if any, are you using on this Vista PC? I've
encountered a firewall software that blocks wireless SSIDs if not told
to trust it.

The Windows Firewall. But WEP works on the computer. WPA and WPA2 do
not work.

Well, I tried it one more time tonight, and it worked. Bizarre. Hmm,
yesterday I had been uninstalling and re-installing different versions
of the wireless adapter drivers, and something must have gotten
corrupted, because after all that, WEP wouldn't work anymore. So I
did a System Restore. That must have also fixed WPA2, because it is
working now.
