I'm having trouble with my wifi connection. Is there any software out there that can help me determine if the problem is in the drivers or in the hardware?

Regretfully, I'm working on Vista

Edit:

The problem I'm having is that the Vista reports that the wireless radio is connected, shows an IP and all, the router also shows that the computer is connected, but there's no connectivity. I can't logon to the router, and I can't even ping it. When I ping it I get the response:

General Failure

• I have tried connecting with and without various wireless security protocols.
• I have tried disabling the wireless adapter and re-enabling it from the Device Manager
• I have tried updating the driver

None of this has helped.

When I connect via Ethernet (with a cable, that is), everything works fine.

Edit:

I'm not using any firewall on the computer, that I'm aware of.

The IP address for the WIFI adapter is similar to the one for the LAN adapter. They differ by one.
