# '''Use [[wikipedia:Wi-Fi Protected Access|WPA]] security'''. If you don't do this, assume ''you will get [[wikipedia:Hacker (computer security)|hacked]]''. ''[[wikipedia:Wired Equivalent Privacy|WEP]] is essentially worthless''. Replace wireless equipment that doesn't support WPA. Seriously. (''See [[#Wi-Fi Security|Wi-Fi Security]]'')

-
# '''Use a ''strong'' WPA passphrase'''. A good way to do that is with [[wikipedia:Diceware|diceware]] words. (''See [[#What Makes for a Strong Password or Passphrase?|What Makes for a Strong Password or Passphrase?]]'') Write your passphrase on a label and stick it on the bottom of your wireless router so you won't forget it. (If someone gets to your wireless router, you are compromised regardless.)
