We have recently aquired a remote location which has a pre-existing flat network (172.16.X.X/16). Before we are able to convert them over to our new IP scheme, they have a need to have wireless connectivity on site. We have 4 1142's which I need to configure for them. I have experience configuring WLC's and autonomous AP's for networks with multiple vlans but have never configured AP's for a flat, single subnet network. I need to configure them for either guest access (internet only) or corporate access to network resources with radius authentication. Do I configure a native vlan as I would for a typical multi vlan network? Do I configure the switch port as an access port as opposed to a trunk beacause of the lack of layer 3? I basically need a sample configuration for this situation.
