Solve the Windows XP + Cradlepoint "Cannot Find a Certificate" Problem

If you're using a computer running Windows XP and you're having trouble connecting to your Cradlepoint router, you're not alone: some XP users see an error message when trying to connect to their Cradlepoint. Luckily, there's an easy way to fix it!  

The Error: "Windows was unable to find the certificate to log you on the network". This error occurs when your Dell, Sony, Gateway, ASUS, Acer, Lenovo, IBM, Toshiba, Fujitsu, or Panasonic computer running Windows XP is trying to connect to a wireless network via a Cradlepoint router. To solve it, you'll simply change the security of the 802.x Authentication.


  1. Go to Start > Control Panel > Network Connections
  2. Right-Click on "Wireless Network Connection" and click on "Properties"
  3. Click on the middle tab, "Wireless Networks"
  4. In the "Preferred Networks" section, select your network and click "Properties"
