Setting Saved Do Not Match The Requirements Of The Network

CUSTOMER -

Our computer crashed and stables replaced the hard drive. When I look at the wireless display in my area my Linksys shows an X. When I click on the link it says: The setting saved on this computer for the network do not match the requirements of the network. We have forgotten our security password as well.

Are you on a computer connected to the Linksys now?
What version of windows is on the computer having the problem?

The first thing we need to do is get your networks password.
To do that on the computer you are on now go to this page: Click Here
Then by default for the username leave it blank and password use admin
Click on wireless and then wireless security.
Your networks password and any security keys should show here.

Now for the windows 7 computer. Click on start and then on control panel.
Click on network and internet. Then click on network and sharing center.
Now on the left click on manage wireless networks.
Click on your network so it is highlighted then click on remove.
After that go back to the network and sharing center.
Then click on connect to a network and connect to your network using the password you just got (if it does not work and there were security keys try one of the security keys).
