Disconnected From The Internet Again

Friday March 22, Good
I had disconnected from the internet again.
So I cleaned the files and I restarted the computer.
But it's still not working.
I got a problem of the internet.
So I checked the hard disk, there was no problem.
And I checked the LAN, internet server also no problem.
The problem was the line connections.
Now I can use the internet.
I thought it was a big problem.
