This might not be simply in one of your ethernet cables. Please keep in mind that the transfer rate is a series of connections is always = the transmission rate of the slowest component in the series. I agree that <a href="http://speedtest.net">http://speedtest.net</a> is a useful tool. Make sure that your speedtest server point is close geographically to your home/office to eliminate as many network hops as possible. Two tests I would run and get data on: Test 1: Browser / PC === Router === Cable/DSL-Modem $$$ Internet Test 2: Browser / PC --- Router === Cable/DSL-Modem $$$ Internet where === is Ethernet and --- is Wifi-n. Note: The type of Ethernet cable makes a difference. Cat5 is older (I'm using it in a pinch, my backup cables). They support 10-100Mbps. This might be what you are experiencing. I'm not there so I cannot see what you see! (-: Do you have a pal with Cat5e or Cat6? A spare at work that you can borrow for testing? Nowadays, I use mostly Cat6 (up to 10Gbps) and Cat5e (up to 1Gbps). Of course, my speed is also limited by my slowest link which happens to be coaxial cable (in my attic) and 2 MoCa adapters (Ethernet to "MoCa" to Ethernet).
