Below are the procedures needed to setup a network key (pass phrase) for your wifi:
  1. Log-in to your wireless router
  2. Find the "wireless security" (or equivalent) settings. Actual screen and wordings would be different depending on the brand and model
  3. Enable WPA/WPA2 encryption and set the pass phrase
  4. Save your changes and reconnect your devices to your wireless network
  5. Done!
Now for some specifics:
  1. To log-in to your wireless router, you need to get the IP address and the username/password of your wireless router. This is normally included in the manual of your router (as if anyone read this).
  2. Common IP addresses include the following:
    • 192.168.0.1 (for D-Link and Netgear)
    • 192.168.1.1 (for Linksys)
    • 192.168.2.1 (for Belkin and SMC)
    Common username:passwords for different brands are listed below:
    • admin:admin (for Linksys and D-Link)
    • admin:[no password] (for Linksys and D-Link)
    • admin:password (for Netgear)
    • You may visit this site for a more comprehensive list of router passwords.
  3. If you can't find the IP address of your router, or you want to make sure that you got the correct one, proceed with this step. Otherwise, you may go to Step 3.
    • Open the "Run" dialog box by pressing [windows key] + R. Type "cmd" (without the quotes) in the text box. Click Ok.
    • Type ipconfig in the command prompt
    • Look for the value of Default Gateway under Wireless LAN adapter. That is the IP address of your wireless router.
  4. Open your internet browser (e.g., Internet Explorer, Firefox, Chrome) and type the IP address of your router in the address bar
  5. It will ask for the username and password for the router:
  6. Once inside, look for the wireless settings (or equivalent) link and set the security mode to WPA/WPA2. Then input your network key/shared key. My screen looks like this:
  7. Save and reconnect your devices.
  8. You're done! While you are logged-in, you may also modify other settings to make your wifi more secure. I will probably make another post regarding this tomorrow (pag sinipag). =P
