"unable to find certificate" no internet

First, click on the wireless icon in your taskbar and under Related Tasks, chooseChange advanced settings.

Now click on the Wireless Networks tab and select the network in the list at the bottom. Click onProperties once you select the wireless network that is having problems.

Click on the Authentication tab and now uncheck the Enable IEEE 802.1x authentication for this network box. If the box was checked, then that was why you were getting the “unable to find a certificate to log you on to the network” message because Windows is looking for one, but your wireless router is not setup for certificate security.
