Troubleshooting Your Internet Connection

A. For wireless connections:

  1. Check first if your wireless Internet adapter is turned on and is able to detect Dilnet WiFi
    For laptop users: Although this may vary depending on the brand of your laptop, you can usually check if the adapter is turned on if symbols such as wifi1 or any similar symbols are lighted up.
    For desktop users: You should have a wireless adapter connected at the back of your CPU tower.  Check if this is lighted up and working.
    If your wireless adapter is turned off, and you are unable to turn it on, have your wireless adapter checked.
    Otherwise proceed to Step 2.
  2. Check if you are able to establish a connection with the Dilnet WiFi.
    Although it will depend on the operating system you are using (Windows, Ubuntu, Mac OS, etc.), there should be a prompt or pop-up window that would notify you whether you have established a connection or not.
    Example:  In Windows Vista and Windows 7, the  icon31 icon often visible at the lower left of your screen indicates that you have an Internet connection. Other images such as icon2 and icon1 indicate that you are connected but may be unable to browse.
    If you are unable to establish a connection:

    • Try to turn off or disable your wireless Internet adapter and then turn it on or enable it again. Then try to connect once more.
    • Try restarting your computer*
    • Try restarting the router by turning it off (unplugging its power cord), waiting for a few seconds, then turning it on again.

    NOTE: ONLY DO THIS IF

    1. You have legitimate access or authority to handle the wireless router in your vicinity;
    2. Other users in the vicinity know that you are going to restart the router (otherwise, they may complain of losing their Internet connection suddenly!); and
    3. All of the users in the vicinity are unable to connect to Dilnet WiFi.

    At peak hours, you may not be able to establish a connection because of high traffic due to the large volume of users. In this case, continually disconnecting and then attempting to connect again may eventually let you gain Internet access successfully.
    If all of these attempts have failed, please do not hesitate to call Dilnet Helpdesk at local 2050.
    If you have established a connection successfully, but are still unable to browse, proceed to Step 3

  3. Check if you are using the correct proxy and if you have set it up properly.
    Please refer to these guides:

    If your proxy was set correctly, and you did not encounter any of the problems described in Steps 1 and 2, please do not hesitate to call Dilnet Helpdesk at local 2050 for further support.

B. For Wired Connections

  1. Make sure that the UTP cable you are using is securely plugged in the correct port.
    One end should be connected to your laptop or desktop, and the other end should be connected to your Internet source (a port in the wall, a port at the back of a router, etc.). If the cable is securely connected to your laptop or desktop, the port should be lighted up.
    If the port is lighted up, but the cable is loose and can get easily unplugged: This may cause problems with your Internet connection. Have the cable re-crimped by a technician.
    If both ends of the cable are securely plugged, but the port at your computer is not lighted up, and your computer is not able to detect a UTP cable plugged in:  There may be a hardware problem with your LAN card. Have your unit checked by a technician.
    Otherwise, proceed to Step 2
  2. Ensure that you have the correct IP settings for your computer.
    Please refer to these guides on how to check the IP settings for your computer
    (Link to guides on how to check IP settings for a Windows, Ubuntu/Linux, Mac)
    If you are not sure if these settings are correct, or if your computer has no saved IP settings at all for your wired connection, please call Dilnet Helpdesk at local 2050 so that we can check and configure your settings immediately.
    If you find nothing wrong with your IP settings, but you still cannot browse the web, proceed to Step 3
  3. Ensure that you are using the correct proxy settings
    For wired, wireless and dormitory connections, use proxy.upd.edu.ph. For more information, please refer to this guide on which proxy setting you should use, and how to check your proxy settings.
    If your proxy was set correctly, and you did not encounter any of the problems described in Steps 1 and 2, please do not hesitate to call Dilnet Helpdesk at local 2050 for further support.
