Dear readers, I am now sitting on my grandmothers computer, which has cabless internet, due to my main PC having been under the accident of having lightning strike on it.

Was sitting on my pc, finish some stuff as the lightning storm was moving onto my house. Before I could finish my work, Lightning struck and a loud pop came, PC froze and I had to cut the power, as it wouldn't react. When I turned it back on, it was functioning properly, but the internet cable would not transmit.

So I turned all of it off, for so to go and take a nap to see if it only was a temporarily problem, sadly, I was wrong.

For now, I am borrowing my grand mother's PC. But I need a solution to my current problem, as I believe the problem I am facing is due to my ethernet port has been fried.

Will I have to replace the whole motherboard, or can I get some sort of USB to CAT5/6 cable adapter for it to work?
Or am I...quite bluntly put, fucked?

Any help is appreciated.
Thanks in advance.
Keny.
