Below is a table of the bandwidth results.
| CAT5e | Powerline Ethernet |
|---|---|
| 637 Mbits/sec | 73.4 Mbits/sec |
| 629 Mbits/sec | 74.0 Mbits/sec |
| 612 Mbits/sec | 74.5 Mbits/sec |
My tests were conducted to favor the Powerline Ethernet adapter. I placed the two Powerline Ethernet adapters within 8 feet of each other in the same room. No extension cords were involved. The CAT5e circuit was a couple of hundred feet and include 2 Ethernet switches between the computers.
Here is the raw output from the
