WPA-PSK encryptions switches from TKIP to AES?

[mckickflip]

Hey everyone,

I've got a wireless connection running as WPA-PSK with a TKIP password. For whatever reason, every few hours the encryption switches back to AES and it disconnects. I have to change it back to TKIP and reconnect again, but how do I prevent this? I have no idea why this would be happening. Running Windows XP SP2. If it makes a difference, I have NOD32 and Comodo Firewall going.

thanks a bunch

I never heard such a story.

What are you connect to? Your Wireless? public? School?

Where it is changing? Source? Client? OS?

Give details.

sorry - this is my home Airport Express (b/g version). no problems with any of my other computers. it's changing only on this PC (Client) in the Windows Zero Configuration wireless tool. i'm using a Netgear WG121. the connection will drop, it will try to resolve a new address but not work, and then I have to go into the Wireless Connection properties to change the network encryption back to TKIP. it's very strange.

Are you sure that the Netgear Utility is Not running too?

Check the running processes.

I'm sure. The Netgear Utility did not even support WPA, so I uninstalled it and have been using the Netgear driver with the Windows wireless utility. Is it possible that the driver is complicating the process? The last version of the WG121 driver came out in 2003.

If their utility does Not support WPA, how come the card does?

Windows gets the card credentials from the Drivers try to uninstall the current drivers, and make sure that you reinstall the latest drivers from Netgear Site.

i will do that. before i put WPA on the Airport, I checked to see if you could get WPA to work with the WG121...my findings were that the netgear utility did not support it, but many could get WPA to work by not using the netgear utility.
