    Wireless Limited or No Connectivity

    Hi: I have a windows vista Laptop, I can not connect to a Wireless Network
    that is using Cisco Network Admission Control (NAC). It is always (Limited or
    no connectivity). I turned off any firelwall and I am sure from the signal
    strength. Please help me to solve the problem.

    In many cases, Limited or no connectivity means the Vista doesn't receive IP
    from the DHCP. Posting back with the result of ipconfig /all to confirm it.

    Thanx Robert. What are the possible causes that it does not receive the IP
    from the DHCP other than the windows firewall specially if all the other
    workstations are receiving receiving IPs normally except this Vista Labtop.

    Thanx.

    Most likely it is indomitable issue. Check any new firmware for the router
    or new driver for the NIC. This link may help too.
