Cannot connect to internet even with ethernet

hi i really need help with this, i restarted my comp after norton ask me to for protection reasons (i didn't read it properly maybe due to scan) but after i restarted i laptop i cant use the internet with it, even though i used Ethernet cable and my other comp can still use the internet. I tried everything that i can find, i tried to use NPE in safe mode with networkin but cant be used due to the safe mode cant use internet. I tried the removal tool and re install norton still the same outcome cant use internet. 

I tried the autofix and it comes out with 2 errors on 2 separate occasions which is : error 8505,129 and error 3047, 91

Please reply fast this is really annoying.

Edit: I tried autofix again and it comes out with a new error 8921,229
