• Windows did not find antivirus software on this computer

  Installed WindowsDefender and Action Center said "windows did not find antivirus software on this computer.

  It is to be expected.  Windows Defender is an anti-malware program that is designed to protect you against spy-ware, and ad-ware only.  However, there is no capacity for the anti-viral.  You should always install an antivirus application any.

  There are several free antiviruss protection applications.  And here are two:

• When I click on my desktop shortcut icons in the new firefox 4 I get a dialog box that indicates that windows does not find that the website

  I have improved the previous version of firefox to the new firefox v.4 and now all the shortcut icons I used with the previous version display a pop-up dialog box that says that windows does not find this website, check the spelling - address - etc. But immediately after this window opens the Web site loads. I tried to load the original site, delete the old shortcut and drag the new shortcut to my desktop, but Firefox always gives me the same message.

  (1) on the last stage Setup lets you start Firefox, if you keep all of the checkbox "Launch Firefox now", turns on Firefox when you click on "Finish"?

• Windows could not find a certificate to log on the network

  So I try to connect to the network that appears, and then trying to connect but it with "Windows could not find a certificate to log on the network. Now, I tried unchecking security in the properties box and also to uncheck it to 'use windows to configure my wireless network.

  NONE OF THESE WORK FOR ME!

  I am currently under SP2, but in the process of installing SP3.

  This error usually occurs because you have specified a connection protocol 802. 1 x.  You must configure your properties to uncheck this box.  See the following article:

• Windows could not find a certificate to log on netgear47

  I have 2 laptops, Dell is connected and the notbook connects without a problem.  I try to connect this old Vaio pcg - K33 K series and the message above. It comes to XP.

  I hung a cable from the router to the computer and can get online but still can't hang wireless.

  Your information is somewhat distorted, but I guess that what follows:

  'Netgear47' is a model of a Netgear wireless router.

  The error message that you get on the Vaio is similar to "Windows could not find a certificate to connect to the network.

  What version AND service pack of Windows XP is installed on the Vaio (right click my computer and select Properties, if you do not know).

  The most likely problem is that on the Vaio's wireless adapter is misconfigured.  If you use Windows wireless zero configuration (WZC) to configure the card (and not a utility provided by Sony), see the following for directions on how to correct this problem: http://helpdeskgeek.com/how-to/windows-was-unable-to-find-a-certificate-to-log-you-on-to-the-network/

  While you are on the "Wireless network connection properties" screen (in the middle of the 3 images on the site linked), look at the box at the top ('use Windows to configure my wireless network').  If this box is NOT checked, then the fix suggested on the web site may not work and you will need to use the utility Sony to make a similar change. In this case, it may be easier to simply delete the 'profile' of your network in the utility of Sony. When you try to connect after you have deleted the profile, the network must be configured correctly.

• Internet connection issues "Limited or no connectivity." and "windows could not find a certificate to log on the network.

  I'm so unable to connect to the internet?

  Hello.

  I'm so unable to connect to the internet.

  Since I've renamed our WiFi network and add a WEP key, I have problems with wireless connection on my
  Windows XP computer desktop, which is a Dell Dimension 4700.

  The questions that I get connection are...

  "windows could not find a certificate to log on the network.

  "Limited or no connectivity."

  I did all the solutions I could try to fix the connection problem!

  1. once I received the message "limited or no connectivity", I click with the right button on the connection and click on repair. It is not always connect for me and I got the "limited or no connectivity message.»

  2. then, I disabled the network connection and then enabled. That no longer works.

  3. I tried to withdraw from the ordered list of connections, and it still doesn't work.

  4. I checked the driver manager, and initially the Ethernet driver was outdated and missing of its pilot. He had a yellow question mark with a black sign and yellow with an exclamation mark inside.

  5. I used DriverZone, downloaded the driver, installed and rebooted the computer after the installation of the it. Apparently, it worked. But I could not always connect.

  6 I have ensured that I entered the correct WEP key, and then adjust the settings correctly. I did it like 10 times in a row and would not always connect.

  7. I tried to go to the command prompt and typed in IP Config/All and that's what I mean.

  Windows IP configuration
  Node type: unknown
  Active IP routing: no
  WINS proxy enabled: no
  ETHERNET connection to the Local network card
  State of the media: Media disconnected
  Description: Intel PRO/100 VE Network Connection
  Ethernet card 2 wireless network connection:
  Suffix the connection-specific DNS: (EMPTY)

  8. after that, I typed the command: ipconfig/release
  and then I got this error...

  No operations can be performed on the connection to the local network, although it has its media disconnected.

  9. after that, I tried Googling for some solutions, and the solutions I found were not any use.
  A solution was

  10. opening of Services...
  Start | Run | Type: services.msc | Click OK |
  Scroll down to and double-click Client DNS | Set to automatic on startup
  type |
  Click apply | Click the Start button | When it starts, click OK
  Do the same for the DHCP Client.
  Do the same for the remote procedure call (RPC).

  and it still doesn't work.

  11. when I look in the menu network connections, I see my connection with a lock on the side, with a red X under the lock and key. In the description, I see not connected, protected by a firewall. How could I remove the internet connection firewall? I disabled the firewall and that did not work.

  12. I tried to uninstall and reinstall the network card and who does not work either.

  It is not the network itself that is the problem.  It is not the modem or the cable. There are no disconnected son or something like that. We have other computers in the House and the internet works fine on other computers. As I said, since I renamed our WiFi network and added a WEP password, I had problems with connecting to my Windows XP computer.

  My computer has updates that must be installed as well. Updates would fix the problem? I just need to have internet.

  What should I do? Thank you for your time.

  Sincerely,

  Justin

  Have you tried to set the value of the link speed/duplex mode? I had the same problem you describe. Your card is only capable of 10/100 communication.
