wired from modem to pc works, wired to router it doesn't work?

[Nunya]

1) Make sure the modem is connected to the internet/WAN slot(it has to be that slot) on the router.

2) unplug the power on both the modem and the router

3) wait 30 seconds

4) plug in the power on the modem and wait until everything is turned on for the modem (approx 30-45 seconds normally)

5) plug in the power on the router and wait for it to boot up completely.

6) test connection again.

7) if problem persists, Factory Reset the router (push pinhole sized reset button for 15+ seconds or until all the lights are flashing simultaneously). Then let go of the reset and wait for all the lights to turn on again

8) setup the router again

9) if issue is still there, router is bad, replace it.
