    I am a student living in university halls where access to a residential internet network is via an ethernet cable which you plugin in your room.

    This has been working fine; however, after a recent windows update - it started saying 'no internet access' (the usual ethernet connection icon but with the little yellow exclamation mark).

    There is nothing wrong with the university network (my friend's internet is working fine next door and a university IT person informed me that it is most likely my computer).

    So, the only way I have been using the internet is by doing a system restore to before the updates were installed - and the internet works fine with the ethernet cable. At least twice now I have left my laptop and the windows update prompt has reached the end of the timer and automatically installed the updates - and again I get the 'no internet access' error and have to do another system restore.

    I am sure it must be the update, but bear in mind that I do occasionally have a 'no internet access' icon and I usually have to restart my laptop and re-insert the cable to remedy the problem. I tried this several times after the updates and I still had 'no internet access'.

    Here's my IPCONFIG/ALL log which might help - but this is after a system restore and before the updates are then installed causing the error (the only way I can access the internet to post on here):

    it does sound like the windows update is doing something - but that ipconfig /all looks OK
    it may be updating a driver
    OR
    maybe the firewall is complaining
    What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, Mcafee , AVG , Webroot etc

    would you post the following tests when the internet is working OK, and then repeat ALL the tests when the internet disconnects.
    Make sure you also indicate on the reply which tests are for what condition.

    ------------------------------------------------------------------------
    ipconfig /all
    If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
    Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

    We would like to see the results from an ipconfig /all - post back the results in a reply here.

    Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box
    (A new dialogue box - black with white font, will appear on screen ):

    In the command prompt window that opens, type the following command:

    Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

    ipconfig /all > network.txt & network.txt

    It will export the results into notepad and then automatically open the notepad and display on your screen.

    Now all you need to do is copy and paste those results into a reply here
    to do that:
    From the notepad menu - choose Edit - Select all
    all the text will now be highlighted
    Next
    From the notepad menu - choose Edit - Copy

    Now go back to the forum - goto the reply and then right click in the reply box and paste the results.
    The results from the notepad should now appear in the forum reply.

    By the way, when I did a system restore after doing the tests with the updates installed - I had the no internet access problem and tried re-inserting the cable several times. So it even had problems when I went back to the state of the computer before the updates. I re-started the computer in safe mode and the internet had access, when I then restarted back into normal mode, it also had internet access. Does this mean that there is something wrong with my normal state that does not exist in safe mode, that is affecting my internet access?

    I cannot understand how that is happening, as 10.34.22.183 is neither the Default Gateway nor the IP address. Usually it is the IP address.

    Probably. That's why Wayne said

    and then asked

    Thanks - should I try the TCP/IP test when the updates have been installed or during this recovered state?

    And using Windows 7.

    My firewall/anti-virus is Comodo. Had a Norton trial years ago, but that has long since been removed. It's only since the updates installed that I have had this problem, apart from the occasional no internet access in the past that has been fixed by a re-insert of the ethernet cable and a reboot.

    after all the updates - see if that clears it
    was the removal tool used - I have seen this cause problems even after years following an uninstal from control panel 2007 i think was quoted

    try that
    --------------------------------------------------------------

    Norton Removal Tool
    I would recommend that you restart the PC and run the removal tool for a second time - I have found instances where the removal tool needs to be run twice to fully remove all traces of norton and symantec from the PC
    https://www-secure.symantec.com/nor...t=Norton Core&pvid=f-core-cur&version=current

    All Versions - The Norton Removal Tool uninstalls all Norton 2010/2009/2008/2007/2006/2005/2004/2003 products, Norton 360 and Norton SystemWorks 12.0 from your computer.

    Hey, installed all the windows updates and ran the commands with these results:

    Code:
    Microsoft Windows [Version 6.1.7601]
    Copyright (c) 2009 Microsoft Corporation.  All rights reserved.
    
    C:\Windows\system32>netsh winsock reset catalog
    
    Sucessfully reset the Winsock Catalog.
    You must restart the computer in order to complete the reset.
    
    C:\Windows\system32>netsh int ipv4 reset reset.log
    Reseting Global, OK!
    Reseting Interface, OK!
    Restart the computer to complete this action.
    
    C:\Windows\system32>netsh int ipv6 reset reset.log
    Reseting Interface, OK!
    Restart the computer to complete this action.
    Restarted the laptop and still got the normal no internet access problem.

    I am now running the laptop in safe mode - for which the internet works fine (even with all the updates installed). So I don't need to do another system restore now that I can access the internet via safe mode to post on here.

    Also used the Norton removal tool and restarted.

    Thanks

    Now time to uninstall Comodo. You can reinstall it after testing.

    Uninstalled it and rebooted - hasn't made any difference i'm afraid.

    unless Terrynet has an alternative suggestion, I would at this point do a clean boot and try and find the offending startup process

    have a read here

    My only other idea, which I think is inferior to the clean boot suggestion, is to do the Windows Updates one at a time to find out which one is causing whatever is happening.

    Extremely confused!

    Did a clean reboot - the internet started working properly in normal mode. Did the checklist for the services - and the internet still worked. Have now allowed all the services and startup programmes to run, rebooted, and now the internet is still working.

    How can this be so? Nothing has changed (as in disabling any programme) from before when the internet was not working to now when it is suddenly working.

    Whether it lasts is another thing!

    Thanks.
