Simply can't connect to router via ethernet

[Cardinal]

I've done this 3 other times, but I already verified the URL to use, and I powered it off 2x. The green light under the ethernet port stays lit and doesn't blink. I was told to leave it off for 30 minutes, and then I'm out of ideas.

What router? What URL?

Perform a factory reset on router.

To perform a factory reset:

On the back of your router, locate the Restore Factory Settings or Reset button.
Using a paper clip or similar object, press and hold the Restore Factory Settings or Reset button for about seven seconds.
Release the Restore Factory Settings or Reset button and wait for your router to reboot.
After your router is finished with the factory reset, the Power light stops blinking and lights solid green.
Note: The Power light on newer router models lights solid white.
The factory default settings are restored. :-[
