You will need to do the following:
Open your browser.
Type http://www.routerlogin.net into the address bar and press Enter.
A login window will appear. Enter the username and password as in my previous post and click OK.
First, go to the Set Password option under Maintenance.
Type in the old password and then type in a new password and repeat the new password (and make a note of it!). Then click Apply.
Now go to Wireless Settings under Setup.
Under Wireless Network, change the Name (SSID) to something that is memorable to you, but different to what it was when your houseguest was with you.
Change Region to your home location.
Under Security Options select WPA-PSK.
Under Security Encryption, enter a Passphrase - it should be a mix of at least letters and numbers and an absolute minimum of 8 characters. Then click on Apply.
Logout from the router.
Now you need to go to your laptop and look for the SSID you have just set.
Come back to us if you have any problems.
