If you find that this is the case, the process described below will be similar, but the steps may not apply exactly. Note: Some computers and network adapters may use network management software other than the built-in applications included with an operating system (especially on Windows). Plugging your computer into another jack will disable that jack as well.
Ethernet jacks on campus are set up to automatically shut off once they detect network bridging. You can use only one network connection at a time. While this simultaneous connection (also known as ‘network bridging’) may be useful on some home networks, it causes problems on the campus network. These two cards allow you to establish simultaneous wired and wireless connections to the campus network. Many laptop and some desktop computers have both wired and wireless network adapters or cards. The Problem with Multiple Network Connections & Network Bridging
