Cisco 1100 :
First config. : no vlan with WEP for access network
But when you create a vlan for wpa-psk with simple config (no server manager, no radius, no eap), have you to modify the other peripherals networks (router...).
For example to declare the vlan.
I did not find this information in the documentation of the aironet 1100.
Thank you for your help.
