    to all!
    I am new to this forum and I have an issue I hope you can help me solve. I recently purchased a Wrt54g an loaded the latest linksys firmware on it 3.03.6. After most pc reboots or when the lease is up I receive an error in my event log. Event ID 1002 Source DHCP. The error basically states the DHCP server (Router) issued a DHCPNACK for the workststion (my pc). This happens on both pc's connected to lan. I spoke to Linksys Support 2x's the first time they told me it was a Microsoft problem the second time I made it to 2nd level support and they told me to use static ip's. Well that works but is not the answer I am looking for. Do I have a bad router??? Thanks for your help.

    This is "normal" behavior.

    What's happening is that the IP address that your PC *had* before the attempt to reconnect is being refused (the DHCPNACK message). This could be because some other PC has been assigned that address; it also may be the sometimes-inscrutable Linksys DHCP logic.

    What then happens is that the router's DHCP logic assigns a *new* address; you'll see a TCPIP message (4201) saying, in effect, that your network card was connected, albeit with a different address.

    I see this all the time with my BEFW11S4 version 4; magically, however, all five PCs here get an address, even if they change from boot to boot.
