I have a Cisco 5500 Controller on my Network. It handles many wireless networks mostly secured with SSIDs. I have a unsecured Guest Network which broadcasts and a DHCP server that gives IP address. It's on a seperate VLAN. All phones android and Iphones and even Kindles connect without a problem. However, I'm trying to connect laptops and that's where the problem lies. If I connect the laptop to one of the secured networks it connects 123 without a problem. It's when I try to connect to the Guest Network that I can't connect I'm only getting a 169 address no internet and the Adapter reads unidentified network. I've tried reinstalling the driver, rebooting, diabling the card etc. I can't connect.
