We can't get DHCP to work with 3rd party wireless bridges

    We have a 3600 controller with mostly 105 access points.  We are trying to use a few 3rd party wireless bridges to deploy a Windows image to our machines.  We've tried one from netgear and one from Belkin.  Both can pass traffic to the PC if we set a static IP on the PC but it doesn't ever receive an address via DHCP.

     

    I was hoping someone else came across this before we open a case.

    TAC was able to help out.  I needed to uncheck "Convert broadcast arp requests to unicast" and "drop broadcast and multicast"

     

    Here is what they sent me:

     

    Please turn off broadcast filter arp/all in the Virtual AP profile and let me know if that works.

     

    To disable the option via CLI:

     

    wlan virtual-ap "<name of the virtual ap profile>"
      broadcast-filter all
      broadcast-filter arp

     

    To disable the option via WebUI:

    Configuration > AP configuration> AP Group > Virtual AP
