Ciao, sto avendo un problema solo quando mi sono collegato ad internet.
I'll write in english since my english is better haha I hope someone can help me out :)

Being more specific, I live in Italy and I have a Telecom Modem... the problem is my notebook 'froze' sometimes that I'm connected, if I'm listening to some music, the music cuts, and the mouse also slow down like 'freezing' and mostly the internet falls and come back in a matter of seconds .. it frozes in few seconds, no need to restart my notebook for a few seconds it returns to normal.
I'm sure that there is no virus...
I'll post some screenshots of my modem, and Wi-Fi connection .. also I'll post my notebook INFO, thanks in advance :)
any doubts let me know !
