NEVERMIND! I changed LAN ports on the back of router. That worked. Now I can log into both websites. Apparently, the Ethernet LED on front of my router was not on beef. I saw this, changed ports, and...

So the power plug and the LAN port cable? What about the internet (ethernet) cable? How will I be able to connect from my desktop if there's no internet connection to my router?

Model : Archer C9 Hardware Version : Firmware Version : V1_161008 ISP : Archer C9 V1 I can not access my router through either address. This did not use to be the case. I do not know what happened....
