How do I restore the routers default settings. I am trying to reinstall a WRT160N router that I just purchased. I had installed it once and then removed it because the internet security would not work. When I tried to reinstall it, the set up wizard said the settings had been changed and I needed to restore the default settings. The second part of the question would be, why would the internet security be "unavailable?" The message that I got from the Network Magic security program that came with the router told me that the wireless security was unavailable for Windows XP w/ 64 bit incryption.

To reset the Linksys back to the default settings - Press and hold the pinhole RESET button at the back of therouter with the power ON for 20 secs. then release the RESET button.
To connect to your wireless router, the router's wireless settings needs to beconfigured with the SSID, encryption etc. and also the wireless cards in allthe laptops/computers needs to be configured with these router's wirelesssettings. Then the laptops/desktop computers can communicate with your wirelessrouter.
Connect a LAN cable from the Linksys to the LAN port on your computer.
Open a browser and enter the Linksys configuration URL

You can protect your router by changing the default PW (write it down and putit in a safe place)
Go to the wireless configuration and set up the SSID and WPA or WPA2encryption.

Press the reset button on the router and hold it for about 10 seconds then the password should be removed or restored to the default one. You will lose all your settings.

On the bottom or the rear panel of the router you will find a small hole that is labeled as "reset."

You will need something small like a bobby pin to insert into the hole, and push the button concealed inside, hold it down until the router powers off and turns back on.

Have you installed the WRT160N router using the CD?
Sometimes when you install this router it will install the Home network defender software. And because of that software you may get error message while accessing some websites.
There is not way to uninstall that software but you can reset the router and reconfigure the router manually without the CD.
Once you reset the router it will come back to the factory default settings and you will need to reconfigure the router.
If you just want to change the internet security then you can open the router setup page and check the access restriction settings.
