Hi this is my first post, and I've been reading Anandtech for years. I have a younger cousin (13) that I help out building and maintaining his gaming rig. He had a wireless networking card but always got poor signal from what I believed a lot of interference from the walls in his old house (70-100 years old). So I suggested he get a power-line adapter (TP-LINK TL-PA4010KIT) so he could ditch the wireless all together. When he got the power-line setup he speed tested only 0.03-0.09Mbps. After a few attempts at trying a few things to fix it, I suggested we hook both adapters to the same power-strip next to the router to see what speed we got. When we speed tested that we got 43Mbps his full internet speed.
Now my question for you guys, have you guys ever heard of an old house's wiring being an issue for power-line networking?
I quick Google search did not return much information. Also the power-line adapter is rated at 500ft and that definitly is not an issue because its well under that. Thank you
