Leave me some feedback if possible ! <| sep |> I just realized that Jim Carrey would make a good joker <| sep |> Windows , I presume ? In Device Manager uninstall the Ethernet Controller . Don ' t check the box to remove the drivers . Then Scan for Hardware Changes and let Windows reinstall the Ethernet Controller . See if that improves your speeds . If it doesn ' t then see if there is a driver update for the Ethernet . Also back in Device Manager , right click on the Ethernet Controller and select Properties . On the Advanced tab look at the list and find Speed and Duplex . Click on it . Make sure on the right it is set for Auto . If all of that doesn ' t help you may want to pick up a USB ethernet adapter to see if you get good speeds through it . In my experience a failing or failed ethernet jack will not slow speeds . There just won ' t be any connection at all . The most common thing I ' ve seen is damage to the pins in the ethernet jack so nothing makes contact and then no connection .
