My computer is not connected to internet.

There can be several reasons why your PC isn't connected to internet. To troubleshoot it, let's undertand what can cause this:

  • 1. Your internet provider (ISP) is having problems.
  • 2. ISP delivers internet but your house has a wiring issue.
  • 3. ISP delivers internet to your modem, but it's faulty.
  • 4. Modem works. WiFi router is faulty.
  • 5. Modem and router work fine. PC fails to receive internet.

  • Step 1. Your ISP may be having technical problems.

    Internet service providers can have technical problems too. Use your smartphone or someone's WiFi to connect to your ISP's user account. It should have a Support page that displays the technical status of your service, whether they are having problems in your area or not. Here are links to major ISP's support page that displays outage information (sign in to see):
    Comcast | Verizon | AT&T | Time Warner | CenturyLink | Charter | Cox | Optimum | Frontier

    Step 2. ISP delivers internet but there is a cabling issue in your house.

    If you check your ISP's outage map and it doesn't report issues, call their 1-800 number and confirm that with an agent. If they say there is no problem on their end but your internet modem doesn't show lights that indicate internet connection, there it is very likely that there is a damaged cable somewhere in your building. In this case you would have to contact your ISP and have their technician check your building's wiring. Once again, check your internet modem's lights to see if it's receiving internet. Internet modem is the decice that your ISP gives you for a $5-$10 monthly fee.

    Step 3. Modem shows live internet, but it's malfunctioning.

    Sometimes modems need a "break". Try the following steps carefully:
    a) Unplug the internet modem from the power outlet.
    b) Unplug the WiFi router from the power outlet. This step does not apply to you if your modem serves as a modem and router (combo device).
    c) Unplug the modem from the WiFi router, but remember which port it was connected to.
    d) Wait at least 10 minutes. Do not cheat!
    e) Plug in the modem to power outlet and wait 1 minute.
    f) Plugin the modem to WiFi router and plugin WiFi router to power outlet.
    g) Wait 5 minutes and check if the internet works on your PC.

    Step 4. Modem works, but you WiFi router is malfunctioning.

    Go to Step 5 if you do not have a separate WiFi router.
    If you have followed everything up to this point, including rebooting the WiFi router on Step 3, it's time to test to take more detailed look into your WiFi router.
    Unplug the modem and router from power outlet, and from one another. Connect the modem directly to your PC, by using an Ethernet (internet) cable. Wait 10 minutes. Power on the modem and let it receive a signal. Check your computer after 5 minutes to see if it's connected to internet.
    This method completely bypasses the WiFi router. If you still don't have internet then proceed to Step 5. If you have internet now, that means your faulty WiFi router was causing the problem and we need to focus on it.

    WARNING: The following will reset WiFi router to factory condition. You will have to configure WiFi password again.

    Unplug the WiFi router from modem and PC (should be unplugged at this point). Plug it into power outlet. On the back of your router, there should be a tiny Reset button that may or may not have the word reset on it. It could also be a hole that you need to press with a chopstick or a needle. Press and hold that reset button for 30 seconds and do not remove it while you're pressing it. You should do this while the router is connected to power outlet. Release the reset button. Connect the modem to router's WAN power and connect the router's non-WAN port to your PC by using a cable. Open a web browser and visit this link That IP address usually redirects to router's configuration window where you can set up a WiFI password. That IP address can be different depending on who the manufacturer is. Use Google to find out your manufacturer's IP address.
    Once you open that page, use admin as username, and password as password to log in. From there, find the area where you can configure WiFi password so your neighbors can't use your internet.

    5. Modem and WiFi work, but your PC still fails to receive internet.

    If you have other devices like smartphones or laptops on your home network, and WiFi works on those devices, that means the internet problem is specific to your PC.

    Windows users:
    Open start and type CMD in the search bar. Open the Command Prompt result. A black window will appear:

    IMG command prompt 1

    Type ping and hit enter. If it reports 0% loss then skip to this tutorial's Step 6.
    IMG command prompt 2

    If you do not see 0% loss and instead receive something like this:

    IMG command prompt 3

    then try the following:

    a) Restart the computer and cehck to see if the internet works.
    b) Right click the internet icon [IMG WiFi icon] and choose Open Network and Sharing Center > Change adapter settings. Find your internet adapter. It is called either Ethernet or has the name that you assigned to your home internet in your router. It could also be named after your WiFi router manufacturer.
    c) Once you've identified the adapter, select and right click on it then choose Disable. Wait few seconds and re-enable it the same way. Visit a website to see if the internet works.
    d) Right click on your internet adapter and choose Properties. Verify that the entry called Internet Protocol Version 4 is enabled. Highlight it and click Properties. Select the option Use the following DNS server addresses: to activate two boxes. In the top box enter and on bottom This will use Google DNS servers. e) Click OK in all the windows and restart the computer (do not forget). Check to see if the internet works.

    If it works, it is very likely that your ISP is having technical problems. Try resetting your router if you haven't done so already.
    If the internet still doesn't work, uninstall your antivirus product and disable Windows Firewall temporarily. Restart and see if it works.
