• My PC loses connection local and Internet after waking from sleep/hybernation.

  My PC loses connection local and Internet after wakes up from sleep/hybernation. The problem is solved by resetting the network card, but it is frustrating to have repeated resets every time the system in place to wake up. I am looking for a patch, I searched all the support sites and forums where there are similar problems that have been offered to different patches over time, but each of them has failed.

  Vista 64 SP2

  Hello

  Check the updated drivers for the NETWORK card and WiFi.

  Control Panel - network - write down of the brand and the model of the Wifi - double click top - tab of the driver - write
  version - click the driver update (cannot do something that MS is far behind the pilots of certification). Then
  Right click on the Wifi device and UNINSTALL - Reboot - it will refresh the driver stack.

• Unable to connect to wireless internet after Windows Vista update on 16/09/10

  Since I've updated windows I cannot access my wireless internet connection, however, I am still able to connect via the LAN port.

  If I check my ipconfig it says under the "media disconnected" wireless network connection  I tried to get my IP address into my settings because they seem to have disappeared, but I can't always wireless.  I ran all Windows diagnostic tools, but all say that the internet connection is fine (due to it being connected by the LAN port).

  I also tried to fix it by other solutions on this forum, that is

  • Open Set Up a Wireless Router or Access Point by clicking theStart button, clickingControl Panel, clicking network and Internet, and then clicknetwork and sharing Center. In the left pane, clickset up a connection or network, and thenset up an access point or wireless router.

  The result of the message is ' Windows has detected network hardware, but it cannot automatically configure "and when I try to manually configure the server requires a user name and password which I don't have.

  Please could shed you some light on this case for me?

  Thank you very much

  Hello

  I tried everything above without result.  However, I managed to reinstall my wireless router software after having repaired my DVD driver software.  I restarted my computer and Wireless does not work.  Reinstalled the software new and restarted the computer, and then after a short period of time the computer connected to wireless internet!  Not know not why the remedy has been delayed or why it did not work after the first attempt, but it connects wireless now - what I know is that this problem occurred after an update of Windows, it's a shame that Microsoft failed to address this problem as it was their update it as many other people have also claimed.

  A big thank you to everyone who offered advice.

• Unable to connect to wireless internet after formatting the system.

  Original title: Mr

  Hi, please my dell Inspiron gives me a serious problem to connect to any wireless router, I can only use moderm to brose, I can't connect to any wireless network, this happened to me after that I have format the system but all other things work.

  Hello

  Thanks for posting your query on Microsoft Community forum.

  As you mentioned after formatting the system, you cannot connect to a wireless router, I recommend updating the firmware on your router and updates your wireless network adapter drivers, as there might be a chance that the wireless drivers are deleted.

  The majority of connection inside Windows 7 problems have been resolved by installing the latest driver for the wireless card with obtained from the manufacturer. Download and install the Windows 7 compatible drivers and check whether the problem is resolved.

  You can refer to the link provided below to update the drivers from the manufacturer's website.

  DELL drivers.

  If the problem persists, I suggest you try the below mentioned methods and see if it helps you to solve the problem.

  Method 1:

  First of all, I suggest you run Windows built-in network troubleshooting to get the problem automatically detected and corrected.

  See the article below to run the network troubleshooter utility.

  Using the troubleshooter from network in Windows 7.

  http://Windows.Microsoft.com/en-us/Windows7/using-the-network-troubleshooter-in-Windows-7#section_2

  
  

  Method 2:

  This problem can also be bound to the adapter, reset, update driver, disabling, re-activating, uninstall and reinstall network adapter can help.

  Follow the steps in the following article to troubleshoot network adapter.

  I have two problems, which could well be related.  Equipped with Vista.  Firefox running, all of a sudden a site using java wouldn't work.  I tried the automatic installation of Java, it has failed.  I tried the manual installation and said "Setup cannot continue with the current internet connection settings" (which is not one of the error messages shown on the help that is aimed at page).

• Can connect to the server (although very slowly) but unable to connect to the internet

  Original title: network connectivity

  I have a user who has been connected to the internet through our SBS server.  All of a sudden, it can connect to the server (although very slowly) but unable to connect to the internet.  The network and sharing shows that it is connected to a public network not by the domain server.

  I hooked another computer for network wiring and it worked fine.  I changed the wiring, and it still doesn't work.

  Any ideas?

• Unable to connect to the internet after the removal of important processes in the task bar

  I am not very tech-savvy then let me explain.

  I have a laptop Lenovo I recently bought in August 2014.  A friend suggested that I have download the free application "Open Office" in line, so I could open a school power point.  Open Office gave me a handful of viruses, which I managed to delete, then having served the system well, panic I accidentally opened the Task Manager and deleted a bunch of processes that are running.

  Now, I find that, although I am connected to WiFi, I can't open Internet.  I click on Firefox, but it shows that I am unable to connect to the Internet.

  I have Windows 8; an easy way I can solve this problem?

  Thank you.

  Original title: I accidentally turned off the program that allows my computer to connect to the Internet

  Hi Tunasushiroll,

  Thanks for posting your query in Microsoft Community.

  I imagine the inconvenience that you are experiencing and will certainly help you in the right direction to solve the problem.

  The problem can occur for various reasons, including incorrect TCP/IP settings configured, firewalls third of anti-virus programs blocking the connection, or due to bad the advanced sharing settings. So, I would suggest trying the following methods and check if you system is able to detect the wireless network.

  Method 1:

  Run the troubleshooter network first, and then test your Internet connection.

  Open the Network Troubleshooter by hitting on any fly in the Dashboard screen, quilting Search(or if you use a mouse, pointing to the top right of the screen, move the mouse down and then clicking search), entering the network troubleshooterin the search box, type, or by clicking settingsand then by typing or clicking on identify and fix network problems.

  If the problem persists, try the following method.

  Method 2:

  Second of all, please check if the WLAN service is started and set to automatic. If it is stopped, then I suggest you to start the service and set it to automatic.

  1. Press the Windows key + R, type services.msc in the Run dialog box and press ENTER.
  2. Select the Autoconfiguration WLAN service in the list and double-click it.
  3. Change the startup to Automatic type, then click Start to start the service.
  4. Click apply and then click OK.
  5. Restart the computer and verify if the network is detected. If this is not the case, go to method 3.

  Method 3:

  Reset the DNS and TCP/IP settings.

  1. Press the Windows key + X, click prompt (Admin).
  2. Please enter the following commands and press ENTER after each one.

     netsh int ip reset resetlog.txt
     netsh winsock reset
     ipconfig/registerdns
     ipconfig/flushdns
     ipconfig/release

  3. Restart the computer to check the issue.

  Check if the system is able to detect the network. If this is not the case, go to method 4.

  Method 4:
  Temporarily disable the security software (if any), and check if it helps.

  Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do not disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks.
