Vista wireless authentication problem

It seems like Vista keeps thinking that this is the wrong authentication mechanism. Is it possible to 'repair' the wireless service in Windows? OK, I think the real issue is that this Windows Vista does not have the WPA2 security type to select which is what the router is broadcasting.

Is there a way to enter this somehow? It seems that Windows determines the available security types based on the driver information for the wireless adapter. Anyway, hope this additional information helps anyone who has a few cycles to provide some guidance.

One option is to disable SPI in your router not possible in all routers , although this will weaken your network security.

The first thing you should try to do is to get updated firmware for your router from the router manufacturer's Web site. There are also reports that some network drivers are not setting the IPv4 checksum you can verify this with a network monitoring tool , and that switching off IPv4 Checksum Offload from the network adapter's Advanced settings will fix connectivity issues.
