  1. Hi,

    I just launched up my PC (W7) and there is a red cross on the bottom right where the network connection is.

    Everytime I launch IE it freezes everytime I launch up firefox it just doesnt load up although I can connect to Skype fine and update software.

    This is really werid, sounds like a viruses blocking internet browser and displaying a cross because I have internet as I just updated my software.

    Virus and spyware scan came up clean

    Any ideas,

    Thanks

    1+2 are real issues that *can* impact you regardless of the network settings, so you may go thru a lot of work and still have issues left over :sigh:

    What has changed? Did you install hardware/software or tweek some settings?

    Nope nothing was changed. Although I did unplug the network cable for a day then had this problem when I plugged it back in.

    I found that if I look in the device manager under netwrok adapaters there are 100s
    Microsoft 6t04 Adpater #1 ... beyond 100

    Also when I go into change adapter settings it just says Select a file to preview im sure I should see the network card here

    Windows 7:
    in order to permanently disable IPv6,
    1) open the registry editor by clicking Start,
    2) then type regedit and hit Enter.
    3) navigate to HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > services >TCPIP6 > Parameters key.
    4) look forDisabledComponents; should be missing
    5a) if present, set all FFFFFFFF into the value; click ok
    5b) else right-click Parameters in the left sidebar and choose New > DWORD (32-bit) Value
    5c) name it DisabledComponents
    6) set all FFFFFFFF into the value; click ok

    reboot

    when done with the above and system is running, you can verify TCP/IP
    get a command prompt and enter ipconfig /all
    you should see the configuration missing all ipv6

    those don't normally cause problems

    get a command prompt and run ipconfig /all >myTCP.txt
    due to all the cruff in it, please attach it to your follow-up

    yes you STILL have IPv6
    Link-local IPv6 Address . . . . . : fe80::54e6:d4bf:203a:cb57%11(Preferred) ​
    go thru the regedit steps to disable it

    Do me a favor.
    Hit the Windows Key + R
    When the Run box comes up, type msconfig
    go to the "Start up" tab
    Give us a screen shot of everything checked (You may have to take more than 1 shot if it's a long list)

    It sounds like something is messing with your configuration on boot.
