Wireless Ethernet Bridge - default gw not pingable

    hardware: asus RT-N66U
    firmware: shibby 108

    I recently purchased a used RT-N66U and I'm trying to set it up as a wireless ethernet bridge to replace an e3000. I'm able to connect clients to the bridge and the clients function properly, tne interesting thing is I can't seem to ping the default gw from the bridge itself. Has anyone run into this before? Another interesting symptum is that "arp -a" take a few mins to complete.

    Yes, same experienced for me. It turn out that problem lies on having same LAN MAC address for both routers.
    Note: Advanced->Routing->Mode = "Router", dont forget

    Leandroong,

    Advanced->routing->mode = "router" is already set on the wireless bridge. I also don't seem to be leveraging the same MAC addresses between the two routers.

    My WEB is working fine. It could be possible that in your router FW has an issue. You need to get opinion with same router from others.

    Issue has been resolved it turns out that I forgot to change the MAC in the Static DHCP entry on the 192.168.1.1 device. Interesting..

    leandroong, thanks for the help.
