If you connect to the wired jack in your room, disable your wireless connection. If you are connected through a wireless connection, unplug your wired connection.
Network loops can occur when your computer uses both its wired and wireless connections simultaneously. If a network switch detects one of these loops, it will turn off the connection of the computer causing the loop. To prevent this from happening, disable one connection when using the other and remove any network bridges Windows installs.

Once the connection is disabled, the "Wireless Network Connection" icon should turn gray and in the status text under its name, it should say "Disabled." When you want to use the wireless connection again, right-click on the icon and select "Enable."
