Trendnet router reset: This makes me feel safer

http://portforward.com/networking/forgot-router-password.htm

Basically, if you ever were to lose the username and password associated with your router, you can put it back to factory settings using the reset pinhole.  On my Trendnet that pinhole is on the front right below the power jack.

For most TrendNet routers, the reset leads to
username=admin
password=admin

See the portforward link up top for more details if this doesn't work.
