Locate Network Information for Your Computer


There may be times when connecting your computer to the UW network (Ethernet or wireless) on campus that you run into problems getting to certain network resources or the Internet.  When reporting the problem to support personnel, there are a few items that may be beneficial to provide to them along with the details of your specific problem to help them in resolving it as quickly as possible: the name of your computer, the Mac address of your computer's network adapter, and the IP address (if one is listed at the time). This document will assist you in locating this information.

NOTE: If you reside in the UW Residence Halls or Apartments and are having troubles with your network connection but are still able to connect to the Internet, go to and fill out and submit the Residential Network Problem Report to help in resolving your problem as quickly as possible.
