DHCP Wireless with Windows 7 bad handshake?



  • Getting a RIDICULOUS problem here…

    Have wifi and pfsense set up here. All laptop users are required to register their MAC addresses before we let them onto the network.

    Put in the MAC address of this kid's new laptop.
    Connected the laptop to the network via wifi.

    pfsense assigns an IP to this laptop.
    But in the pfsense/diag_dhcp_leases.php, I see:

    00:60:b3:30:0f:a4    2009/10/29 15:53:23  2009/10/29 15:58:23  online  static

    No IP address showing here, although the laptop already received its random IP. It's even able to ping other laptops in the same network.

    But the laptop will not be able to access the gateway. Can't get on the internet.

    It's as if pfsense has given the IP address to Win7. Win7 received the IP without giving back some kind of acknowledgement. Pfsense, not receiving the ACK, continues to block that MAC address.

    Had to get around this by assigning a fixed IP address to this MAC address.

    And when I do this, I would get something like:

    192.168.0.55  00:60:b3:30:0f:a4    2009/10/29 15:53:23  2009/10/29 15:58:23  online  static
    00:60:b3:30:0f:a4    2009/10/29 15:53:23  2009/10/29 15:58:23  online  static

    pfsense will give this MAC address 2 IPs. The fixed one, and another dynamic one.
    And Win7 will sometimes use the fixed one. And sometimes use the dynamic one it, at which point, it won't be able to access the net.

    MIGRAINE!!!
