Ethernet port damaged?

Last night, I was on the internet on my Dell desktop just fine. This morning, my internet stopped working. It says I have no connection in the icon in my bottom right tray. The internet works on my laptop, when I plug in the ethernet cable, however. I noticed that my desktop’s ethernet port’s lights (orange and green) don’t turn on anymore. Is this a sign of broken hardware - damaged ethernet port?

I’ve already tried:
[LIST]
[]start > run > cmd > ipconfig /release - but it says I must have a connection before I can do this
[
]reinstalled all the drivers that came with the PC
[]restarted the DSL modem
