Hello Guys, Maybe you know something about "Notebooks / PC", because I have got a problem:

My Internet breaks every 30 secounds, on Call of Duty's it laggs ( Bad Connection ) for 30 secounds and then for 5 secounds not (everytime)

With my Internet Cable it works without problems, but with WLAN not...

I have got a good connection, the WLAN - BOX (Router) is next to me

But why that happens and not by Cable?

I have got Windows 8 64-Bit and Norton Internet Security ( Maybe that should be my problem, but I don't know how to fix).

And the troubleshooting wont help me ( No errors detected )


I hope, you can help me and fix it Thank you!
