Unable to connect to the internet! Help?

It stopped working a few days ago and contains the symbol of the triangle. He says its a unidentified network. When trying to troubleshoot it, it says 'Connection to the Local network' is not a valid IP configuration or she can't identify the problem at all.
What I tried:
-my computer stop and wait 10 seconds as it says
-restart my router
-put manually the IP myself
-go in safe mode
-then some other random attempts to get it to work

You must go about it methodically.  To help you do this, we need to know how your computer is connected to the Internet.

Because you talk about 'Connecting to the Local network' and your "router", it sounds as if your computer is connected to a router using an Ethernet cable.  What is the brand and model of the router at the other end of this Ethernet cable?  If you please, look at the label on the back or the bottom of the unit and include the brand, model and hardware version, if any.

Is this router connected in turn to another device or it be plugged into an outlet on your wall?  If you connect to another device before you plug it into the wall, please give the version of make, model and equipment, if any, of the other device.

You pay for your own Internet service, or connect to a network by a school or a business?

I guess that you do not use this computer to ask your question here.  How is the device you use to ask your question connected to the Internet?  In other words, you use another computer or Smartphone connected to the same router?  If Yes, is it connected by Ethernet or wi - fi?  Or are you just using a smart phone and its cellular data connection?

Basically, you need to determine if the issue is (a) on your computer, (b) in the connection between your computer and your router, your router, (d) (c) in the connection between your router and the Internet (which includes internal and external cabling, server of your ISP and other things all out of your control).  Given the answers to the above questions, I can suggest some tests that will help narrow down where is the problem and then what to do to fix things.

    Concerning

  • E3200 unable to connect to the Internet

    I bought a new E3200 to replace my old Linksys router.  It finds my computers and set up a network, but unable to connect to the internet via my Comcast cable modem.  I read on this forum to the questions of the Mac address, but it has located the Mac address.  Internet IP address is all zeros, and releasing and renewing the IP address does nothing.  Help!

    Connect to the computer with the Ethernet cable. Check if you are able to access the Internet.

    Open the command again.

    And do the ipconfig/all.

    Note the physical address in the Ethernet connection to the LAN card.

    Connect the Modem to the Internet Port of the router and also connect to the computer with the Ethernet cable to the Ethernet port on the router.

    Press and hold the reset for 30 seconds button.

    Cycle power to the modem and the router.

    Open the Linksys router configuration page.

    Go to the Mac address Clone and activate it.

    Enter the physical address that you noted.

    Do not click the Clone my PC MAC, Save the Settings.

    Cycle power to the modem and the router. See if you are able to access the Internet.

    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.
