Hmm seems your not static because your using a DHCP server. See if the other computers on your network that can access the internet see if they have the same default gateway as the one from this PC...........If it is then ->
Open the CMD prompt again,
Type "ipconfig /release",
then after that type "ipconfig /renew"
It should pull the next available IP in your network. Then see if you can access the internet.
If you still can't, it could be possible you have malware blocking your internet connection? I would download www.malwarebytes.org free version and run a full scan and see if it finds anything.
