We are having a constant problem w/ our business laptops accessing our guest wifi, instead of our restricted & incripted WEP key needed, network. So users call to tell us that they can't access the network . We go on site & see windows managed wireless has attached to the guest acct . Then we go to network properties remove guest , move up to the top the facility network wireless we want then our employees can continue to work. This was not happening until we installed our free wifi for guest. Also we have checked connect even if not broadcasting for our network. And placed a bullet in advanced properties : connect to access points (infastrure preferred) network only. Help please. It doesn't seem to matter the brand name or model of laptops , we use Dell Latitude, Fujitsu e8110 it happens on both.
