  • 1.  DHCP Problem on one SSID after changing IP Adresses

    Hiho again,

     

    hope someone can help again :)

     

    I have a Controller 7005 with some AP-215 and two different SSID on it, one is the internal with PSK (WPA2) auth and the other is for guest access via voucher (user/password). After changing the ip adresses of the controller and ap`s i have a problem with the internal wifi, i didn`t recieve an ip adress from external DHCP server. If i try to connect to the vlan via cable, it work fine. If i connect to the guest wifi, it work fine.

    On my internal wifi i didn`t get the ip settings from DHCP, before changing the ip adresses everything works fine.

    Any idea mates?

    Thanks first for your fast help.

    If you cannot establish a connection to the DHCP server anymore, verify, that there is a route from your new SSID VLAN to the DHCP server and check if ip helper addresses are configured on the Layer 3 boundary (router, Multilayer Switch).

    A simple restart of the controller fixed the problem...sry for that late info.
