One computer not connecting to internet

[clariongrade]

Hi

I had connection from all my computers until yesterday.

Yesterday, the Sky router has taken a dislike to one (my main) computer.  It connects to the router, and gets a IP Address.  The router shows that the IP adress is connected, but the computer reports no Internet.

I can ping 192.168.0.1 from the computer, but I cannot connect to it from the computer browser.

I can ping local computers, but not anything the other side of the router.

I have tried changing the ethernet to a USB dongle.  I get a new IP adress, but still no Internet.

I am using another WiFi connected computer to write this, so the internet is working for this device.

Does anyone have any ideas?

Thanks

Do you have anything running on the PC that could cause a non connection such as a VPN with a kill switch ?
