    I have three laptops I've tried to connect to a Motorola SBG900 cable modem. The two laptops with XP Pro connect to the modem and internet with no issues. The third laptop with Vista Home Basic will connect to the model but won't connect to the internet.

    If the Vista laptop is connected to the model via USB it will connect. If connected with either LAN or wireless, the connection is local only.

    I've tried the following:

    Entering IPv4 IP address
    Entering DNS server address
    Turning off the firewall
    Reset WINSOCK entries
    Reset IPv4 TCP/IP stack to installation defaults
    Reset IPv6 TCP/IP stack to installation defaults
    Disabled the IP Helper service
    Disabled IPv6
    Disabled the DHCP Broadcast Flag

    none of this did anything

    Finally I tried turning off the Avast Network Shield and it connected. One of the XP laptops has Avast too, but it didn't have the same issue.

    Clearly, there is a configuration or compatibility issue with the Avast product. What is the question here?
