I have read through some of the questions on the site, and none of them quite fit my problem description. I recently had to put a new hard drive in my computer after a media failure on my Dell N5110 running Windows 7. After I reinstalled the hard drive, it will not detect the Ethernet if plugged in. I reinstalled all the drivers that Dell is offering on their website and none have done anything. In the device manager under network it has no device with Ethernet mentioned. Also when the Ethernet is plugged in, no lights are blinking in the port. The WiFi works, and they said it might be a hardware issue. Could I have messed something up I there when I installed the new hard drive?

If the network adapter is not listed in Device Manager & there are no errors showing in there, it is definitely a hardware problem. The network adapter is no longer working, so as far as Windows is concerned it doesn't exist. Whether you damaged it whilst installing the new hard drive I cannot say.

Since it's a laptop, you can't simply install a new network card in it so you'll have to continue to use wireless which is what most laptop owners use anyway. Wired connections are rarely if ever used on a laptop so it's no great loss as long as wireless works.
