DNS Lookup Failed Error on my Browser

Asked By 10 points N/A Posted on -

Why is it that when I type a web address in Google Chrome, I get the message that the DNS look up failed?

Same is true when I use Firefox. I use a CAT5e Ethernet cord to be able to connect to the Campus-wide Local Area


All seems well as my computer says that there is an internet access and able to recognize the cable plugged to it.

You will get a DNS failure only if the computer is not communicating with the network. It also caused by DNS software installed in Windows but the common problem is with the connectivity between your computer and the network.

Check the Local Area Connection and this will display the status of your connection. It'll tell you if the computer is not recognizing the cable connected.

To go to the Local Area connection, do these steps.

Go to Start, Control Panel

Then Network and Internet

Network and Sharing Center is next

Change Adapter Settings

Local Area Connection should say Network

If it's disabled, do right click and Enable it

However, if the status is saying the Network Cable is Unplugged, then you have to secure the cat5 cord connected. Unplugged and replugged if necessary, if nothing happens, why don't you use different cat5 cord to isolate the problem.

The status should change from Network Cable Unplugged to Network or Connected if the cord is being recognized by your computer. It is also possible that the other end of the cat5 cord is loose. You may also do the same steps on what you've done on your computer side.
