Windows Update does not work - 80072EFE error (Network adaptor problem?)

    Question

  • [System information:

    Windows 7 Home Premium (32bit OS)
    Samsung R520 Intel Core 2 Duo T6500 2.10GHz 4GB
    Realtek RTL81E Wireless LAN 802.11n PCI-E NIC (Driver Version 2000.4.201.2010)
    Marvell Yukon 88E8057 PCI-E Gigabit Ethernet Controller]


    My father's laptop encounters the 80072EFE error (Windows could not search for new updates) when attempting Windows Update via a wireless network adaptor. Windows Update via wireless internet appeared to have been working before I noticed this error. 

    I have tried all the following suggestions to no avail:

    Updating with anti-virus and firewall turned off

    Made sure time and date settings are correct

    Ran Microsoft Fix It (relevant version for Windows 7) in both Default and Aggressive modes

    Reset Cryptographic services (deleted Catroot2 folder)

    Checked for malware and viruses - none found. The laptop can connect to any website

    Ran tdsskiller - nothing found

    Flushed DNS resolver

    Reinstalled Windows 7 twice - it's a relatively new and unused machine



    However, connecting the laptop via an ethernet cable to the same router that the wireless network adaptor is connected to works: the Windows Update is successful every time.

    Although, there were no error messages pertaining to drivers, I reinstalled the driver to the wireless network adaptor with the same current version (there is nothing to rollback to and I cannot find an earlier compatible version), but this does not resolve the problem. I've rebooted the router, but this does not change things either. And, in case this adds anything useful, I have no problems with another wireless laptop on the same router, running Vista.

    Am I right in thinking the wireless adaptor or its driver is the possible cause to this problem? Could one of the Windows Updates be conflicting with the network adaptor? If so, which one is it likely to be?

    Or could there be an issue with the router and/or the way that is set up? If so, what should I change on it?

    Also, does anyone know of a pre-version 2000.4.201.2010 driver (for Windows 7) for the Realtek Wireless network adaptor? I cannot find one on either the Samsung or Realtek sites. I'm guessing if one does exist, then this would be worth trying.

    I am grateful for any advice or help in solving this problem.

    Many thanks

  • Thanks, Andre. 

    This was something I had already tried, but with no joy. I gave it another go, but the problem still remains.

    Thanks again for your time.

  • derosnec, 

    Thanks for your reply.

    I looked at the WinHTTP, BITS and Windows Update settings in 'Services.msc', but everything looked fine. (I compared the settings with a desktop running Windows 7 through the same router via ethernet - they were the same.)

    I'm sure the rest of the article refers to the Windows Server OS. Also, 'proxycfg' has been removed in Windows 7; 'netsh' has replaced it. I've not had time to use netsh today, but will give it a go tomorrow and see if reseting or changing any values helps.

    Again, thanks for your help.

  • Which AntiVirus/firewall do you use?

  • Andre,

    Norton Internet Security 2010 is/was installed; both AV and firewall options are used when it's running. But, I'm as certain as can be that it's nothing to do with the anti-virus or firewall software for the following reasons:

    1. Nothing changes when I turn off or uninstall the AV and firewall software (including turning off the Windows OS Firewall).

    2. On each occasion, when I've restored the OS, I did not install any AV software and turned off the Windows Firewall. Yet, the problem still occurred. 

    Having just restored the OS again, the problem occurs after Windows Update has installs all the updates. In other words, it works fine without a firewall and AV software (and possibly with them), until after the first time all Windows Updates are installed. This is why I think that one of the Updates is conflicting with the WLAN setup. I've no idea which of the 60 Updates it would be, though.

    Thanks for your help

  • derosnec,

    Please see my reply to Andre above, re: AV/firewall information.

    All the settings referred to on the link you gave are set at Automatic. There were no strange or erroneous values.

    I did say in my previous posts that I could connect to any website, but I've just tried to post to this forum using my father's laptop, but can't get passed the Windows Live logon screen. This is the first time I've tried this, having posted to this forum before via my own laptop.

    I have read elsewhere about some people who have a similar problem with Windows Update also have issues with MSN Messenger and using Windows Live. So, hopefully, this new symptom might help with the diagnosis.

    Haven't tinkered with the 'netsh' yet.

    Thanks for your help.

  • derosnec,

    Thanks for your helpful reply.

    Yes, by restore I mean that I've used the Samsung Recovery software to restore to the 'initial' state of O/S and the software that the laptop was delivered with there was no Windows 7 O/S disc. with. This was from the laptop's partition. I added no other software after the recovery.

    I tried the encrypted.google.com link, but I could not connect to it via WLAN. I also couldn't connect to it via the ethernet LAN. 

    There's nothing going on with ICS that I can see.

    I switched off IPv6, but that did not appear to do anything. And on the Wirless Network Connectivity Status window, against 'IPv6 Connectivity' is says 'No network access' when using either the WLAN or ethernet. I haven't managed to spend too much time looking at this, i.e. swapping back and forth between WLAN and ethernet, but I'll give it some more time this weekend.

    I've also tried the following which might be getting nearer to the problem, or at least exhausting the possible solutions:

    1. Uninstalled all the updates one by one, unless I was required to restart the computer, until there were no updates bar the one that Microsoft were required to produce to enable fair competition for internet browsers. This did not solve the problem.

    2. Did a complete restore of the O/S (using the Samsung Recovery software) to revert to the state the laptop was shipped. It found all the updates to download - the correct amount to install. I began to install each update individually, with the intention of seeing which one was causing the problem. I began with the earliest. After installing it, I got an 80072EE2 error. To all intents and purposes the laptop behaved in the same way as with the 80072EFE error. I didn't think I was that lucky, so tried a complete restore again, and selected another update at random and got the 80072EE2 once more. I did this one more time with another update and got the same results. It seems whatever update I install first on the restored system, I get the 80072EE2 error. 

    I did all of this with no antivirus or firewall installed (I turned off the Windows 7 firewall). All other internet connectivity (except Windows Live where I can't get passed the login, and where I get an 80048820 error) works.

    So a new error code (80072EE2), although seemingly the same symptoms.

    Now I'm thinking that there is something about the initial state of the laptop and not the updates per se that is causing these errors. 

    Thanks for any more light you can throw on this.
