Did I fry my router's WAN port with a cable tester?

I have a cable tester and was trying to able all of my cables in my network closet to see what's going where and accidentally plugged the cable that goes to my router into the cable tester. Router turns on and UI works but the it's not getting any internet connection what's ever. I did a factory restart as well to no avail. I have a NETGEAR XR1000 router.

Am I cooked? I opened it up and saw no visible damage to the transistors or motherboard but alas it seems like it's not connecting to the internet.
