Hi,
My Internet access is extremely poor at the moment. The ethernet adapter does not appear to be working and wireless works but goes down as well.
Some of my error messages are:-

And

I solved this and it had nothing to do with any configuration settings. My connection via ethernet wasn't working as a hardware issue.
