Free tool from MS

"The Internet Connectivity Evaluation Tool checks your Internet router to see if it supports certain technologies. You can use this tool on a PC running either the Windows Vista or Windows XP operating system.

If you're planning to run Windows Vista, this tool can verify whether your existing Internet router supports advanced features, such as improved download speeds and face-to-face collaboration using Windows Meeting Space.

The tool is intended to be run from a home network behind a home Internet (NAT) router. Running this tool from behind a corporate firewall or on operating systems other than those specified above won't produce accurate results. This tool requires administrator privileges to run.
