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.

The tests can require up to 10 minutes to complete and do not make any permanent changes to your router. For the most accurate results, your computer should be connected directly to your Internet router, using a wired connection.

Note Although it is unlikely, testing might interrupt your Internet connectivity or cause your router to stop responding. If you require uninterrupted Internet access at this time (for example, if you are in the middle of downloading a large file, bidding on a time-sensitive Internet auction, or playing an online game), you should wait and do this testing at another time.
