I shut down my wifi.
Let me explain..
I don't like wifi on all the time. Only when I am websurfing or watching a youtube video etc.
But I mainly turn it off because my laptop has unusual and suspicious activity with updates and other such tasks running every 5 or 10 minutes, or at random times.
"SoftwareUpdate.exe" is a big no-no to have running, it slows down my system and takes hours to finish. That is a Google product cataloging all my files. Its evil. Every time I remove it, it magically comes back. And there are other suspicious updater scanning type apps that I turn off and they too magically comes back to life. They are unecessary to be running every few hours, let along every day. So I turn off wifi.
