    im using avast, since it was the only free antivir for windows 8 when i was looking for one. so i guess some software is causing the problem (never had to use safe mode till now, you never stop to learn )
    ive never changed any MAC setting on the router!
    I'm not surprised about it working in safe mode.

    In that case you will definitely want to remove Avast completely using the special uninstall tool. Very typical problem by the way.

    so you think it was the antivirus after all?

    i tried disabling avast it but the browser still wouldnt open a page.
    now that i recall, when i bought the laptop there was a test version of mcaffee on it. during that time i didnt have any issues! ill try removing avast when i get back from work,is there another free antivirus programm that you would recommend for windows 8.

    ty very much!

    When you installed the Avast anti-virus, Windows should have created a restore point. Go into the system restore console and roll back your installation to the point where you installed Avast and see if that fixes your problem. Windows 8 is extremely fast on the restore process as compared to earlier versions. 5 minutes and you are back to where you started before installing the AV software. I have given up on 3rd party AV programs and just stick with the built in Windows Defender on Win 8 and the Microsoft MSE on Win 7.

    These third party A/V's tend to cause countless problems with Windows 8. The preinstalled Windows defender is the way to go if you do not want any problems.

    If you had McAfee on your system you should run the McAfee uninstall tool because there may still be traces of it on your system that could cause problems.

    Use malware bytes to perform scans plus use the real time security in Windows defender.

    The password in question is probably associated with either McAfee Family Protection or McAfee Anti-Theft. In either case if you don't know what it is then I suggest you contact McAfee Technical Support, it's free by phone or online chat here: Services and Support for Home and Office

    You'll need to change your Country to wherever you are at the top right corner.

    That said, the Network problem is probably easily sorted out, they may be able to fix it. Probably a case of 2 or more networks in Windows Network and Sharing Center and the software needs to be told which one to use. I find disabling any unused ones in Device Manager helps with that. iPV6 being relatively new is causing many people headaches from what I read on the web. Thankfully my ISP hasn't been forced to adopt it, yet.

    Well it's unfortunate that the problem came back, still it has absolutely nothing to do with IPv6, the fact that the connection works in safe mode proves that. Although it's obvious to me that removing Avast did have an effect as you already stated.

    You will want to remove which ever parts of McAfee are left on your system.

    This is the removal tool to use for that.
    Download McAfee Consumer Product Removal Tool 6.0.151.0 Free - Will remove all McAfee consumer products - Softpedia

    If you can go into Device Manager and then to Network Adaptors, disable the Bluetooth adaptor and the Msoft Virtual adaptor you see there under Network Adaptors, as these can sometimes cause connection problems and it's best to disable them when testing.

    The McAfee software only identifies whatever Windows Network is seeiing and is perfectly compatible with iPV6, and the removal tool wont remove Anti-Theft, Family Protection or anything that requires an Admin password to release it. That's where support is best for this.

    Ipv6 negative.

    I knew it was an installed AV because of the safe mode with networking test.

    It's interesting how obvious the answer is once the problem has been solved.

    Please feel free to mark as solved Stellar.

    Just to avoid any confusion on the origin of this problem, I'll quote my second post here after I reset winsock and TCP/IP.

    That's good, it narrows the problem down,. You do show a valid IP so something is blocking the connection.

    Most likely your Anti virus or third party firewall is causing the problem. Which one are you using?

    Starting up in safe mode with networking is a good way to determine if the problem is caused from an installed program, if the problem goes away in safe mode then something was installed that is blocking the connection.

    And the internet access for IPv4 and no access for IPv6 is perfectly normal.
