Offices & Labs--Usb-to-ethernet adapters
Modern, lightweight laptops increasingly come equipped with wireless network cards only. While these devices offer great advantages in terms of mobility, a corporate network environment such as in Trinity College requires wired network connectivity for access to certain services. If you own a wireless-only laptop and you need to connect it to the wired network in College, please read the information below carefully.

- Purchasing a USB-to-Ethernet adapter
- Usage and security information
- As part of the College data network policy, anyone using a PC running Microsoft Windows in College offices and labs must configure their computer to join the College domain. This requires a wired network connection. If you wish to connect a wireless-only laptop to the wired network then you must purchase a USB-to-Ethernet adapter, as outlined below. Note that all other standard network connection requirements also apply in this case.
- Computers running Apple Mac OS X or Linux do not have to join the College domain, and therefore a wired connection is not required by policy. However, certain services can only be access from a wired network connection and so if you wish to connect a wireless-only laptop to the wired network to access these services, outlined below, then you must obtain a USB-to-Ethernet adapter.
- The following services and features require a wired network connection, irrespective of the operating system in use:
- Editing College websites
- Accessing certain shared network folders
