okay, so I have Comcast Xfinity, and my router is located in my bedroom. It provides decent WiFi to everywhere that I need it, especially since my office is directly below my bedroom. My house doesn’t have any Ethernet ports, only phone lines. I have tried moving my router into the office and connecting it through the cable port down there but it doesn’t work, even when I called and reset it. I need to connect my desktop to the internet via Ethernet, and don’t want to use a wireless adapter plugged into my desktop. So, should I call Comcast and have them come to my house to reset my router for down stairs, or could I get a WiFi extender and plug it in down stairs and run my desktop to it using Ethernet? Which way would provide the best internet connection on my desktop? I’m more inclined to get an extender but if that slows my internet down then I’ll just have Comcast come by. Any help is appreciated, thanks in advance.
