I recently built a new PC and ever since I have been having issues with my WiFi dropping in and out. I have been using a Netgear wireless adapter, but am interested in getting Ethernet set up for my room. The house was built in 2002, and has no Ethernet ports set up anywhere. The router and modem are currently set up in the basement, and the room I am wanting to get Ethernet to is on the second floor. I have COAX and phone line outlets in the room, but no Ethernet. I was wondering if it would be possible to get Ethernet without drilling a hole in the wall? I know very little about anything related to networking, and have no idea where to start. Thanks!
