My dell computer suddenly won't connect to the internet and won't recognize my internet connection.

If you right click on my computer and go to manage you should be given a window with the device manager listed. click on device manager and all your devices will be listed there. if any have a question mark than more than likely your driver is not installed or installed incorrectly. if there are any red exclamation marks or red x's than your device is not working or disabled. you can always right click on the device and go to properties to read further about it. if it is disabled you can try to enable it here but you may have to enable it in the bios durring the boot up process of the computer. if none of this is the case or does not work than your ethernet port probably got surged and no longer work a sure way to tell if this is the case is to look at the port the lights should only come on if the cable is plugged in and the computer is turned on. if the lights do not come on or stay on even when it is unplugged than your port is bad and you can just run to walmart and get a pci network card for like $15.
