RunningMan: Sounds like there is connectivity of both are getting valid IP address in the right range. Have seen an issue a couple of times with it trying to use IPv6 when there isn't a valid route.

Try going in to the advanced settings and flicking IPv6 off

As of now, I am connected via USB Ethernet.
Configure IPv6 is set to 'Automatically' (which I have never touched).
The only 2 other options are: Manually Link-local only

In the terminal (coy / paste)

sudo networksetup -setv6off wi-fi
sudo networksetup -setv6off ethernet

Check this goto System Preferences.... Network click on TCP/IP and check IPV4 is configured to DHCP click on DNS and check the servers are correctly listed

Give this a try, goto System Preferences.... Network.....click on the Advanced button locate bottom right....Highlight each network listed and click the minus button to remove, do this for all listed.
Exit prefs and save if prompted, reboot and try again to connect

Re:

Create a new user in the users and groups system preferences. See if you can connect from that account. If yes, then there may be a corrupt network file in the main account. I agree that it may be something to do with DNS server settings.

Done. But no joy.

It's back on-line.

1) IPV4 was set to DHCP
2) In DNS, there was NO DNS Servers listed. I manually added 192.168.1.1 (My router) and it connected.

Thank you.

Why would it be missing.
Is there anything else I should do?
