I try to configure 2 ssid's for 1131 autonomous AP. One SSID with open authentication and WEP encryption and the other SSID using WPA. The "WEP-SSID" is in guest-mode. So i can see the "WEP-SSID" in the list of available W-Lans on a notebook but WPA protected and not WEP protected. An other issue is the unability to get a IP address from a DHCP server for wireless stations using the "WEP-SSID"-network. Any ideas for these behavior ?
Make sure the DHCP server is in the same subnet as wireless client. If it is in the different subnet, ensure that reachability is there between these devices. Send me the debug ip dhcp enable command and send me the debug output.
