    My son's laptop stopped accessing the internet. We use a home wireless
    network via linksys router. The computer says there is a wireless connection
    present, but I cannot get the computer to access the internet. Diagnostics
    in IE7 says it's a firewall rpoblem, but this perists when I turn off the
    firewall. I am told this happened shortly after an update that failed. ANy
    ideas?

  2. Always state your full Windows version (e.g., WinXP SP3; Vista SP1) when
    posting to this newsgroup, please.

    Can the machine connect directly via the router or modem?
    What update?

    Hi Brian,
    Try System Restore to an earlier date when things were working okay.
    Disable your Anti-virus then restart in Safe Mode by tapping the F8 on start
    Up until you get the Boot up options and select Safe Mode.

    In safe Mode click Start >> All programs >> Accessories >> System Tools >>
    Ssytem Restore and pick up a Restore point to restore your system.
    It will do the reboot and the rstore will procedure pay attention to it and
    see if it was successful or not.
    Do n't forget to Enable your Anti-virus after a successful Restore and
    hopefully it will also resolved your problem.

    If that didn't help try these commands;
    Open a run command and type in:
    ipconfig /flushdns click [OK]
    ipconfig /renew click [OK]
    netsh winsock reset click [OK]
    Reboot the Laptop and see if you are able to access the internet.
    HTH,
    nass

    Pa Bear: Sorry about the version information. He runs XP SP3. I am not
    certain about which update, and my son could not remember. Trying to
    reconstruct the events of the internet failure from the informaiton of a 12
    year old has proven difficult to say the least.

    Thanks for the advice. I learned (after the fact) that the system restore
    function was not enabled, so I do not have a prior date to restore. I tried
    the run commands, but with not luck. I note also, that an alternative web
    browser also failed to recognize the internet connection.

    Okay Brian, can you ping the Router?
    Try to Power the router Down for about a minute or so, also the Laptop.
    Turn the Router ON back and wait for 40-50 seconds tehn Power Up the Laptop,
    are you able to connect?
    Can you provide the output for ipconfig /all and post back.

    It will be helpful if you posted to this Wireless NG as there are lots of
    Experts there they can help

    Yes. The affected computer can connect diretly to the router.

    If Windows XP can connect to the router, but Windows XP cannot connect to
    the internet, perhaps you need to revist the router settings.
    You could also try recycling power to the router.

    This seems to be a frequent problem with Vista and wireless connections, my be due to IE7 and it
    reports a policy problem related to the firewall. That is a lot of BS and the Windows Firewall
    changes wont fix it.

    Some times it will come back if you reboot. But it always comes back to working when you run
    "winsockfix.exe"

  11. Let me rephrase my question for clarity: If the machine is connected
    directly to the router or modem, can it access the internet?

    Does the laptop have a wireless switch that was accidentally toggled into
    the OFF position? It sounds like a dumb thing to check but it happened to
    me.
