    I have a combination modem/router supplied by my internet service. My main floor desktop computer is connected directly via Ethernet cable. Two laptops, an ipad and a couple of TV's connect wirelessly. I have a large house with an office in the basement which is pretty much underground and on the other end of the house, so I recently ran a second Ethernet cable from the upstairs modem/router to a desktop computer in my downstairs office. The connection itself worked fine. I did notice, however, that my wireless connections would not work when the second Ethernet cable was plugged into the modem/router. When I unplugged it, wireless started working again. Could the problem be with the Ethernet cable? It is a CAT 5e cable which I made myself since I needed a custom length. It is my first one, so of course I am doubting myself. It works fine except for the problem it creates with my wireless devices. (My level of expertise is a little more than beginner, but I'm not quite sure I would call myself intermediate yet either.)

    Check the settings for the ethernet and wireless devices in that basement desktop.

    Some computers will disable one device when the other device is being used.

    TerryNet and etaf and a few others are the networking experts here, so one of them will probably jump in to help you.

    Let me try to get a better understanding. If, say, two devices are connected by Wi-Fi and have internet access and then you connect the new cable and computer, do both wireless devices drop their Wi-Fi connections to the router or do they maintain the connections but no longer have internet access?

    Thanks to you both, flavallee and TerryNet. I actually spent some time on the phone this afternoon with my internet provider and although tech support could not find anything wrong on his end, things seem to be working on my end, at least for the moment. While I have no idea what the problem has been for the past three days, I at least know that my Ethernet cable was not the problem. I appreciate your quick responses! Best regards!
