Since moving my Internet is less than stellar. My gaming pc has a Realtek GBE family controller on my gigabyte b75m-hd3 motherboard. I have had numerous speed issues speediest says my device only recieves max 120 on a 200 mbs tier and the connection shows a gigabit connection, the Realtek diagnostic shows there is no problem. after 2 service calls they say my pc is the issue and say I have a 300mbs service but I cannot get this to happen myself. Any ideas.
