still reading around so a few things to check ...
- Click on the networking icon in the Notification Area and then right click a connection. That brings up a menu that can be explored and you can "forget this network" or "view connection properties." > Then remove / choose forget the network that you no longer want to connect to.
*** ALSO, see if theres any difference when you enable or disable the IEEE 802.1X authentication OR change it to another one of the options.
(1. Enter/connect to your wireless network.
2. Under the Network and Sharing Center in Control Panel click on your Wireless network and on the screen "Wireless Status" click on the button "Wireless Properties"
3. From here you can manage the option for this particular wireless connection such as encryption type, if it connects when not broadcasting,etc. You want the Security Tab.
4.From the Security tab you can use the drop down for "Security Type" and select 802.1x and modify as required.
That above enables 802.1x authentication but now that you know where the option is you simply have to change that Security Type from 802.1x to something such as Open or WPA-PSK or which ever option is best for your network.. )
