No Internet Access on Startup/Restart RRS feed

  • Question

  • Problem: On boot up/restart, receive No Internet Access message. Also, LAN is unavailable.

    System: Just out of the box Windows 7 Home Premium laptop connected through a router to a cable modem

    Additional information:

    • According to the ipconfig, the computer connects to the modem rather than the router for its IP/Gateway/DNS which gives it the wrong subnet, gateway, & DNS
    • I have had the same experience with desktops running Windows 7 Pro; the same hardware configuration under Windows XP Pro has no problem.
    • A Macintosh laptop (OS 10.4) had no problem connecting to the wired network
    • VariousPocketPCs, iPhones & iPads have no problem connecting to the wired network
    • Problem occurs whether connecting wired or wireless

    I can get the adapter to work correctly if I do any of the following:

    • Manual IP addressing
    • In the cmd.exe window, ipconfig /release followed by ipconfig /renew
    • Uninstall the network adapter & reboot (Windows automatically reinstalls the adapter)
    • Use with a combination router/firewall/modem (eg, an Actiontec of ZyXel modem on DSL with no intervening firewall/router)

    The following solutions have failed to correct the problem:

    • Updating the network adapter driver
    • Disable the network adapter, restart computer, enable the adapter
    • Connecting the cable after logging in
    • Connecting the cable before startup or restart
    • Restarting the router/firewall
    • Turn off 'Allow computer to turn off this device to save power (Network Adapter Properties: Configure)
    • In the cmd.exe window, netsh winsock reset
    • Starting up in Safe Mode with Networking
    • Disabling the wireless adapter & connecting via wired (& vice versa)

    The few solutions which actually do correct the problem are not feasible as the laptop will need to connect with different networks, and it will be used by someone who is not comfortable (and probably not safe) working with advanced features. Not to mention it's inconvenient and shouldn't need to be done.

     Some final data:

    Ipconfig results after startup using Auto IP/DNS (No Internet Connection):
