Can't connect vgn21 to access point trendnet

[anto_u]

The log indicates that the notebook is associated but windows vista can't connect to the access point. It works with a D-Link access point, not with Trendnet.
My second notebook, a Dell, can connect via Trendnet.

- do I need a new driver?
- do you have a software for the wifi chipset (so I can connect avoiding vista)?

Thanks for your help!

If it's an intel card in your notebook you can get the latest driver from intel.com
