Windows help page I want to enter this command, press enter and he would immediately return to the following command-line (with no info)?  I typed in ipconfig/all and IP of Windows Configuration it is said...

• 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.

• Unable to connect to the internet update version

  I've updated to the latest version 35, but since then, the browser seems unable to connect to the internet. I thought it was my firewall that was blocking the program. I did what was suggested to work around this problem, that is, to remove my firewall and then add it again. But it does not solve the problem. There is nothing wrong with my internet, how am I be able to connect to internet by using IE or Chrome. And I was able to connect to the internet in the previous version of Firefox. Unfortunately, the new updated version is not allow me to. Have no solution?

  It is possible that your security (firewall, antivirus) software blocks or limit Firefox or the process of plugin-container without you inform, possibly after the detection of changes (update) for the Firefox program.

  Delete all rules for Firefox and the plugin-container in the permissions list in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

• Satellite L300-1 a 6 - unable to connect to the internet

  I have a problem - unable to connect to the Internet.

  First of all, I try to use internet DSL from phone, there was no result.

  Then I try to use digital TV internet - no result.

  Laptop does not detect a network, it says - undefined network.

  My firewall is active, now I use a modem to laptop...

  Sorry, but I don't understand how you have configured your DSL router/modem.

  First of all, you need to configure the router and need to insert all the data from your ISP (Internet service provider).
  Usually the model or DSL with router assigns the IP address. Therefore, only connect your LAN cable to the LAN books and you should get a connection to the DSL router/modem.

  I think that in most cases the whole process is described in the manual of the router
