My internet goes off

Well, that ... suddenly goes off and I just resubmitting it to connect ... what happens?

Is going many times. Thanks in advance.

If you have it configured so you can get an automatic IP address, try to manually configure it by setting your DNS and IP's

also happens to the screen at times when power fails, that is really a virus? I downloaded the AVG ... to see what happens.

Good, let's first see it from the Internet. Anyway an antivirus and antispyware have to be installed, if not.

On WiFi or cable?
