    I just had a technician come to my apartment today and install a wired connection to the router. However, my computer is still using Wi-fi, and it doesn't recognize a wired connection. My ethernet cable connects to an RJ45 port, where there is a cable running underneath the carpet to the router. I suspect that the ethernet cable running from my computer to the port might be faulty, but want to make sure there's nothing else wrong with it before I replace it.

    Have you disabled or turned off the wireless and then restarted the system with the ethernet connected?

    When you look in Device Manager under Network Adapters, do you see something besides the wireless?
    Is there a light on, on the back of the computer at the ethernet port?

    If you find anything else like ploder mentioned, go to Network & Internet Settings > Change Adapter Options and see if it says Network Cable Unplugged for the Ethernet Connection. If it says Limited Access, then check the properties by right clicking on the Ethernet Connection > Properties > select Internet Protocol Version 4 then Properties and make sure Obtain an IP/DNS Server address automatically are selected.
