they were paired in reverse somehow my computer was trying to send internet to the modem Also it says in the Utility that the speed is 56mbps not 600mbps

It says I have an internet connection on my computer but when I try go load a website or use the internet I get a no internet connection error. My modem is working fine as I can use any other device...

I got this yesterday and it worked fine yesterday afternoon. This afternoon when I turned on my computer it was fine after about 2.hours it stop working middle light is not on either powerline...
