Troubleshooting: No Internet/Page Not Found Error

March 3, 2015

If you get a Page Not Found error, Server Not Found Error, or similar, here are some things you can try to fix the problem. If none of these things help, give us a call and we’ll fix it for you.

When you use a web browser (Internet Explorer, Firefox, Chrome, Safari, etc.) and try to contact a website, you might get a Page Not Found error. This means that the web browser was unable to contact the website. There are several things that can cause this issue. Here are the less complex fixes.

  1. Check Your Internet Service
    1. If you have other computers using the same service, can they access websites?
    2. Look at your modem (the box with the lights on it) to make sure all of the lights are green.
    3. If other computers are unable to access the internet, or if the lights on the modem don’t look right, unplug the modem, wait 30 seconds, and plug it back in. Now wait 2 minutes and see if it starts working again.
    4. After rebooting the modem and waiting 2 minutes, if the lights still don’t look right, call your Internet service provider. There could be a problem with your service or with your modem.
    5. If the above didn’t help, check to see if you also have a router (another box with lights on it). If so, unplug it, wait 30 seconds, plug it back in, and wait 2 minutes to see if that fixes the problem.
    6. If you have determined that the problem is not your internet service, try the following:
  2. If your computer is connected to the internet using wireless
    1. If using a laptop, look on your laptop for a WiFi switch. This is usually a sliding switch that turns your WiFi on and off. If your laptop has one, it might have gotten switched off. Switch it back on and wait a minute to see if that fixes it. Some laptops have a key combination instead of a sliding switch. Look for a key on the keyboard called ‘fn’ using in blue or orange. Now look on your keyboard for a key that has a wireless symbol in the same color. If you find one, hold down the fn key and press that key once and then wait a minute to see if it connects.
    2. Try disconnecting and reconnecting to the wireless. Remember that you’ll need the WiFi password to do this if your WiFi has a password, which it should.
      1. On Windows 7, right-click on the network icon and choose network and sharing center. On the left, click on Manage Wireless connections. Find your wireless connection and click on it to select it and click the remove button at the top. To reconnect, click on the network icon and click the wireless connection and click the connect button.
      2. On Windows 8, click on the network icon and a blue bar will slide over from the right with connection details. Find the one  you are connected to and right click on it and tell it to forget the network. To reconnect, click on the connection again and click the connect button.
  3. Check for Proxy
    1. Click on start and the control panel.
    2. Click on Network and Internet (listed in green)
    3. Click on Internet Options (listed in green)
    4. Click on the Connections tab
    5. Click on the LAN settings button
    6. Under proxy server, make sure there is NOT a checkmark by “use a proxy…” If there is a checkmark, click on it to clear it and click OK to save and try again.
    7. NOTE: Infections often set this proxy settings. If after you clear this setting, if it comes back, your computer is probably infected and you should give us a call to clean it for you
  4. Check DNS
    1. Click on Start and then Control Panel
    2. Click on Network and Sharing Center (listed in green).
    3. Over on the left, click on “Change Adapter Settings”
    4. Find the correct adapter. If your computer is connected to the internet with a wire, it probably says Ethernet or Local Area Network. If you are connected via wireless, try to identify it. If you can’t figure out which one it is, double-click on each one until you find one that says Internet to the right of IPv4 Connectivity.
    5. Once you have found the correct Network adapter, right-click on it and choose properties.
    6. Now find Internet Protocol version 4 (IPv4) in the list and double-click on it.
    7. Make sure the following two settings are selected
      1. “Obtain an IP Address automatically”
      2. “Obtain DNS server address automatically”
    8. Click OK and try again.
    9. As above, if these settings magically change back after you change them,  your computer is probably infected and you should give us a call to clean it for you.
  5. Try a different browser
    1. It could be the browser you are using has been hijacked.
    2. If you have a different web browser on your computer, try using it to see if it works.
    3. Common web browsers include Internet Explorer, Firefox, Chrome, Safari, and Opera.
    4. If you don’t see an icon on your desktop for one of these, click on start and then All Programs to see if you can find it in there.
    5. If you find another browser and it works, then the other browser you were using has been hijacked which means your computer is infected. You can either just use the new web browser that isn’t hijacked or you can give us a call to clean the infections off your computer.
