DHCP problem with dd-wrt v23

    Hello there,
    the day before yesterday I installed v23 generic on my wrt54gs.

    Everything worked fine; I started playing arund a bit and oops - my notebook doesn't get an IP anymore. Windows (XP Home) just states it's obtaining an IP but I can wait as long as 20 minutes and nothing happens. It seems like getting an IP fails and starts over and over again.

    The other machine (XP Pro) which is connected by cable doesn't have this problem.

    Maybe I should add that I misconfigured the MAC-filter once. When reconfiguring and applying the right settings, I didn't get the "settings applied successful"-screen. After that, the issue came up.
    I changed the settings via my wired machine but there's no difference.

    Connect by CAT5 cable, check your MAC filter settings.

    I once got locked out as the MAC filter setting somehow changed itself...

    I did exactly what you proposed some time before. But it seemed to change nothing.
    Then I resetted the device to factory defaults. It worked again, but only until I changed the SSID and the channel. The I got factory defaults again and didn't touch the channel setting and the SSID. Now it seems to work, bets are open how long and until which configuration change...

    I think probably I'll downgrade to v22 again.

    Ensure that the 'Routing and Remote Access' service is not disabled on your XP Wireless Machine.

    Set your DHCP lease time to something higher than the default 10 mins....such as 720 mins (12 Hours)

    Everything worked just fine before I upgraded from v22 to v23.

    What made me wonder was the fact that the "DHCP lockouts" happen somehow randomly after changing of settings which don't have anything to do with DHCP, like MAC blocking or SSID/channel changes. (means: I stopped playing around with the settings once I had a stable setup. Thats a bit sad :thumbdown: )

    This is a known problem with v23 final. You should use SP1 (I use fro m 03-Feb) and the problem is solved there. QoS is also working ok.
