    This is a strange issue. I have gotten around the issue but need to collect some information.

    I can connect wireless at many sites. At my work location, I can connect and receive an IP address. When that address is .255 I can connect but not get on the network, IE, etc.

    The network folks insist that is a good address. However, to get around that issue they have now blocked the DHCP server from issueing that address. Everything works ok now.

    The network folks have raised the question as to something in the wireless card, wireless driver, or laptop (Dell Mini 10) with XP that might not allow that address.

    Any information would be appreciated.

    .255 is broadcast, you should never get that...unfortunately there's not enough information to tell you anything other than that

    If you are getting a .255 IP address, you have used a mis-configured DHCP server somewhere, sometime. The relevant DHCP 'zone' is misconfigured.

    This doesn't have to be a zone at work either. Anywhere you connect via wireless can be at fault. Many times a computer that is using DHCP will try to renew the last IP address before actually requesting a new one.

    That your office networking folks insist that .255 is a valid address is more troubling than the address itself........
