How can I secure my wireless Internet from others using it?

Open your Internet browser and type in “192.168.2.1” in the address bar to see if you get your router settings window. Then setup a WEP or WPA key.

A few options… Easiest being to password protect the connection within the router (WEP/WPA). Most secure being to restrict access to everyone except for those on a list using mac address filtering.

I suggest using WPA2 if you have that option in your router. WEP is old and easily crackable. WPA is better but WPA2 is great. Totally secure. Make sure you choose a strong password. A good tip is to use a sentence with a few words spaced with special characters like @#_=/^$%!*(). That would make a good password.

all the above suggestions are good. What you also want to do is to disable the broadcast SSID. The SSID is the name of your router. By default this sends a message to all computers(including your neighbors) that there is a wireless router nearby. Turning this off won’t affect anything.
Next go into your router software and tell it to only allow your family computers to use your wireless connection. Each computer has a unique I.D. that is established by their wireless card.

@LuckVIII Good call. I totally forgot about this because I set my current config up so long ago… Disabling broadcast SSID will “hide” you from everyone within range. One would have to know the name of your network connection to even have the option of connecting.

i agree with all these responses, just go to 192.168.2.1 or 192.168.1.1
then in settings add a wireless password
