Networking Questions and Answers - Network Connection Icon Says No Connection
Jake writes in with a networking question Question:My internet doesn't always work. I'm at college and I have my computer plugged into the wall through a cable. Sometimes it works but other times it says that I don't have internet access, it has a little yellow triangle over the connection symbol. Could some of my setting be wrong somewhere on my computer? How can I have internet connection all the time?
Answer: If you are getting the no connection symbol on your network connection icon it's usually because of a physical connection issue more than an internet problem. When that icon appears it's because it's not detecting a connection on both ends of the cable. Even if the device that's connected to the other end of the cable didn't have an internet connection your computer would still detect the Ethernet connection going through the attached cable.
This can be caused by a number of things. You may have a faulty cable going from the wall to your computer. Your Ethernet/network port may have a short or the network card itself may be having a problem. The wiring from the backside of the wall to wherever it goes may be faulty. Or the device or port that is on the other end of the wiring may be having a problem. I would replace the cable from your computer to the wall first and then try to narrow down any other connection problems. If this is a college facility then you may want to contact their IT support and see if they can test the cabling from the wall to their equipment.
