How do I change the password on my wifi?

You have to kno the ip address of the router.. Type that into ur browser.. Should bring up ur browser settings.. From there I guess u gotta explore and find the wep or wpa passcode The last part depends on ur router

1.Click on the icon for your wireless internet in the Windows 7 taskbar. The icon looks like an escalating series of white bars.

2.Right-click on your wireless connection in the window that appears.

3.Click "Properties."

4.Click on the "Security" tab.

5.Check the box next to "Show characters" under the box labeled Network Security Key.

6.Highlight the current network security key with your mouse. Press the "Delete" key on your computer.

7.Type a new password in the box.

8.Click "Apply." Click "OK" to change the Wi-Fi password for your network in Windows 7.

Probably the easiest way to do this operation would be to just do an online search of your router model and inquire about instructions about setting/changing the password using either WEP or WAP. You'll get lots of video instructions from YouTube for the exact steps necessary to answer your question. For example just use your browser to search...How can I change the password on my Linksys wireless router model WRT54G?...and you'll get lots of links that will explain the procedure. Just choose the one that fits your capabilities best. That would be the easiest way to help you I know of. I've used this method of educating myself and it works well. Hope this will help. Good luck!

Type your ip address in your web browser and go to settings and change it.
