Click on Properties 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.
Then, I selected disable at the "wi fi protected setup (wps)" option.
This seemed to work for me after I disconnected from my router and reconnected again.
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. Once I unchecked that box and tried to reconnect to the wireless network, everything worked fine!
cheere Hadn't read all solutions so I apologize if I'm repeating someone but all I did was go back to Belkin router setup utility, or (192.168.2.1) and clicked "wi fi protected setup".First, click on the wireless icon in your taskbar and under Related Tasks, choose Change advanced settings.Now click on the Wireless Networks tab and select the network in the list at the bottom.If the Enable IEEE 802.1x authentication for this network box is checked, it will trigger the “unable to find a certificate to log you on to the network” message because Windows is looking for a certificate but your wireless router is not set up for certificate security.Step 6 Select the Connection tab and check the Connect when this network is in range box.I recently bought a new Linksys wireless router and after setting it up with basic WEP security, I tried to logon from my laptop and was successful! So then I tried to connect from my desktop computer that has a wireless USB adapter attached to it and I ended up getting this error message: Fabulous! I checked my settings on the wireless router to make sure I didn’t accidentally setup certificate security, but found no such thing.
