Set a Password For Your Home WiFi Network

If you have WiFi and live in an apartment building, you may notice there are lots of other WiFi networks visible on your network list (and naturally, your neighbors can probably see yours as well). Although this fact alone isn't dangerous, it can be if your own network isn't password protected. Leaving your wireless signal open could put you at risk of intruders illegally downloading on your bandwidth, stealing personal info, and even gaining access to your personal documents on your home computers and laptops.

So when setting up wireless Internet at home, make sure you set a password that is long and hard to remember so your home network isn't hacked. Read through your wireless routers instructions carefully for step-by-step instructions. And, hey, Mac users — just because your computer is at a lower risk for viruses, that doesn't mean your wireless can't be hacked as easily as everyone elses, especially if you're using a lame password!
