For years I have used an ethernet connection that uses house wiring to transmit the signal from the modem to where I keep my PC. Recently the device started to give me trouble, often showing no internet service. Finally I just unplugged it and used regular WiFi to make the connection, which seems to work but is slower when accessing websites than was the ethernet connection when it was working right. My question to you tech savvy folks is: do these devices just give up the ghost after awhile and should I just buy a new ethernet set up, or are the problems I had in losing connection to the internet an expected problem when relying on house current to and from the modem? Because of the layout of my house, I have no option of running an actual ethernet cable from the modem directly to my PC.
