Log in to the router.
If you don't remember how, then that's where the name and model of the router come in handy.
click on start
click on run
type ipconfig /all
look for the default gateway.
Type that address in the address bar and hit enter
put in the correct username and password
somewhere in wireless settings or security, you'll find WPA security.
Use this and type in your password. Use a combination of letters and numbers.
Now when you try to connect, you'll have to use the password to log in.
Hope this helps.
I have had an unsecure network for some time now, and I would like to change that. I would like to add a password, change it so you need a key to get in. The problem is, I don't know how to get back to change the settings on my wireless network. I looked all over and couldnt find how to change the settings. Can anyone help? I have Windows XP btw.
