Wireless Disconnecting - Windows 7 64-bit mostly


Several Windows 7 64-bit systems (laptop computers mainly) seem to loose their wireless network connection at varying and not specified times under varying circumstances.

Searching in Google and in Microsoft's support forum I found three different methods documented that seem to have done the trick for various people. I post these methods here in an attempt to give at least some help.

Method 1: Disable IEEE 802.1X authentication
To disable IEEE 802.1X authentication, follow these steps:

  • Click Start, type ncpa.cpl, and then hit Enter.
  • Right-click your wireless network connection and click Properties.
  • Click the Wireless Networks tab.
  • In Preferred networks, click your wireless network and click Properties.
  • Click the Authentication tab, click to clear the Enable IEEE 802.1X authentication for this network check box, and then click OK two times.

Method 2: Remove and re-create the wireless network connection
To remove and re-create the wireless network connection, follow these steps:

  • Click Start, type ncpa.cpl, and then hit Enter. 
  • Right-click your wireless network connection and click Properties.
  • Click the Wireless Networks tab.
  • Under Preferred networks, click your wireless network and click Remove.
  • Click View Wireless Networks.
  • Under Network Tasks, click Refresh Network List.
  • Under Choose a wireless network, click the wireless network to which you want to connect and click Connect.

Method 3 requires to work within your router.
If you are not used to do that - frankly, you better call me.

But for those of you that are not faint of heart: Here it is, written for a D-Link 655 router. If you have a different router the same things may be called VERY differently; be cautious!

  • Un-check WMM (Wireless Multi Media)
  • Un-check Short GI (Guard Interval) and
  • Un-check Extra Wireless Protection.

Warning: These are methods that have helped other people with this problem to varying degrees. If you have a D-Link router I might actually try method #3 first.

Either way you apply any of these methods exclusively at your own risk. I did not have this problem and thus can not test any of the above.

As usual I welcome comments and suggestions right here in the blog. Thank you in advance.

Set-Up Job


Edited March 9th. 2016: Block Windows 10 from snooping and Picasa discontinued
 
Every brand name computer you buy in a store or on the internet brings with it three areas of concern: Gunk software, missing updates and costly and questionable "security" software. I'll address these three concerns separately and then offer my suggestion to deal with these concerns before they become a problem.

1. Gunk software: Brand name computers come with some (and sometimes a lot of) "gunk" software pre-installed. You'll find anything from trial versions of programs that will cost additional money to outright spyware and even back door programs.

It goes without saying that this gunk should be removed before you even connect the computer for the first time to the internet.

I even consider programs like Microsoft's Internet Explorer and MS's email programs and Microsoft Office trial versions to be "gunk". By virtue of the very technology used TO WRITE them (called ActiveX) they will enable a large percentage of malicious software to be executed on your computer. Just by using alternative programs that were built without ActiveX technology you avoid all this malicious ActiveX software automatically.

Microsoft's Office is by now always a trial version; it will cost you additionally about $100 to $150 depending on where you buy the product key that you will need to use MS Office for more than 60 days.

There is a commercial program being offered to do this removing of gunk software but the computer manufacturers regularly modify what they pre-install and the names of what they install. Thus a program attempting the clean-up will almost always be outdated and work only incompletely. Or it will offer you a list of installed non-Microsoft programs and ask for your decision on what to remove; and you bought the program because you don't know that in the first place!

2. Missing Updates: The brand name computer you buy was designed and originally configured months ago, sometimes many months ago. For good reasons software companies like Microsoft, Adobe and others regularly release security relevant updates. Microsoft does that on a monthly schedule, others do it when required.

All these mandatory updates from when your computer model was designed until when you bought it are missing. That mostly is a lot to download and install. These downloads should be done in a safe environment to protect the machine from eventual hack attacks before all required updates are installed.

3. "Security" Software: All of the commonly pre-installed anti virus programs or "security systems" will in the future cost additional money. Some are considerable, clearly perceivable heavy workloads making your computer slow; see this article for real life experiences with security suites slowing down perfectly well working computers.

Some others are not always working correctly and/or proving their questionable quality by not un-installing correctly or quietly stopping to work altogether.

After seemingly error-free uninstalling of some security suites I have found that they left sometimes parts of their software still running. Due to the nature of what these programs have to do these left-over drivers and orphaned processes can wreak havoc.

This clearly calls for a knowledgeable human doing the uninstallation and checking for left-overs.

My Solution: I offer a set-up job for new brand-name computers; I even offer a fixed price if I can do it at my house because I can overlap some of the time with answering my emails and other activities.
This set-up job includes:
  • De-gunking the computer (manually and completely removing unwanted, potentially risky programs and all kind of trial software)
  • Updating the operating system and all other software in a safe environment 
  • Installing and updating (or enabling) free security software (currently Microsoft Security Essentials on Win7, enabling Windows Defender on Windows 8.x and Windows 10)
  • Edit March 2016: On Windows 7, 8.1 and 10 I install a free program that blocks Windows from reporting back to Microsoft what you do and how you do it (I call that spying!).
    Since about November 2015 Microsoft has begun to "enhance" Windows 7 and 8.1 with some of the reporting features of Windows 10. That is called progress...
  • Installing Mozilla's Firefox web browser, my choice as alternate web browser including the best available advertisement blocker and a utility that warns you if search results would lead to known malicious web sites
  • Installing Mozilla's Thunderbird email client if so desired including the best available advertisement blocker
    • Installing Libre Office (Microsoft file compatible office software)
    • Installing Google Earth
    • Installing Picasa (photo management and editing program);
      Edit March 2016: Only upon request; the Web Album Service is discontinued by Google;
      you can keep using Picasa to organize, edit a.s.o. locally stored pictures just as in the past and  there will be no more program updates for Picasa (the current version is VERY stable!).
    • Installing an easy to use screen shot program (so you can send me the pesky error message that is bugging you)
    • Installing a remote control program that enables me to give you remote support  
    • Replacing the always out-of date pre-installed version of Adobe Reader with a free, faster and safer alternative called PDF-XChange Viewer
    • Installing a virtual PDF printer; it creates PDF files from anything you can print. You don't want to email a job application as a Word document that anybody could modify! 
    • Establishing desktop icons leading directly to Documents, Downloads, Pictures and so on. 
    • On Windows 8 and Windows 10 install a proven, small program that starts the computer directly into desktop mode and establishes a Start button and a Programs menu like we got used to in Windows 7 or Vista or XP.
    All above mentioned software is of excellent quality, officially FREE for home use and guaranteed to be free of advertisements and spyware.

    Should you be interested please send a personal email to ejheinze_at_gmail_dot_com; thank you.

    As usual I welcome comments and suggestions right here in the blog. Thank you in advance.

    Stay safe!

    LibreOffice - What Is It - Installed Correctly

    Once upon a time there was an office software suite called OpenOffice, worldwide free (as in no money!) and used in many European and third world countries. OpenOffice was an OSS system. The technical infrastructure (server computers, storage space a.s.o.) for this sizeable project was mainly supported by Sun Microsystems, a now defunct computer manufacturer. Then the software behemoth Oracle Corp. bought Sun and got OpenOffice as an Easter egg with the whole basket. They, Oracle, imposed some fees and apparently a whole lot of red tape and typical "big company" overhead which did not sit well with many of the major developers, that is the programmers who mostly as volunteers wrote the code and did all the nitty-gritty detail work.

    Quote from another blog:

    "Oracle's imposition of fees for some OpenOffice capabilities caused some of the venerable open source office suite's creators to head out on their own and create LibreOffice as a truly free OSS tool."

    So the developers of OpenOffice spoke, parted from Oracle's realm and alas, we had LibreOffice.

    Basically LibreOffice is almost exactly the same as OpenOffice, only better. Better because it can read files from Microsoft Works and Word Perfect and handle SVG graphics files.

    There are two major differences:

    1. OpenOffice came with an always outdated Java version and LibreOffice requires a Java environment already installed on the computer. If I have set up your computer that is covered. If I did not set up your computer you need to install the most current version of Java and remove all older versions.
    2. OpenOffice came with Help files integrated in one huge download, LibreOffice comes in two files; you need both.

    There are a few things you ought to know if you want to install LibreOffice.

    1. Install or update to the latest version of Java (as of July 2011 version 6 update 26 is current).
    2. Remove (un-install) all eventually still existing older versions of Java.
    3. Remove (un-install) OpenOffice - if it was on your computer at all.
    4. Download LibreOffice from this web page. As of end of July 2011 the current stable version id 3.4.2. You need two files:
      1. LibO_3.4.2_Win_x86_install_multi.exe, the LibreOffice installer program.
        Caution: This is a 214MB download!
      2. LibO_3.42_Win_x86_helppack_en-US.exe, the installer for the Help package.
      3. Above version numbers will be different for future versions!

    Some important installation instructions (not meant to be comprehensive!):

    Install LibreOffice itself by running the installer in file LibO_x.x.x_Win_x86_install_multi.exe.

    For everything here not explicitly mentioned you can accept the default values/selections.

    When you are being asked to select the type of installation please select Custom:
    ScreenShot001

    You will have to de-select the following features:
    In Optional Components the Python-UNO Bridge:
    ScreenShot002

    In LibreOffice Program Modules de-select Draw, Base and Math; it should look like this:
    ScreenShot003

    Then select all three Microsoft Office modules:
    ScreenShot004

    Install the Help package by running the installer in file LibO_x.x.x_Win_x86_helppack_en-US.exe.

    With these hints you should be able to install LibreOffice with the ability to open and write Microsoft Office Word, Excel and Powerpoint files. If you prefer to have me do the installation then please download both files that I mentioned above, I can do the rest remotely.

    After the installation you will find two folders named "LibreOffice 3.x (random) Installation Files" and "LibreOffice 3.3 Help Pack (English) (random) Installation Files" on your desktop. Please delete these two folders.
