Issues:
Cannot get to internet site, but can ping router or DNS.
Issue IPCONFIG command from command line with switches
ipconfig /flushdns - removes the cache that translates human-readable address to IP address.
ipconfig /renew - renews the IP address if your pc gets an IP address automatically/dynamically.
Issue NETSH command from command line with switches
netsh interface ip delete arpcache - removes the cache that translates IP addresses to physical MAC addresses--(essentially is the next level down from DNS).
