3C900-combo - Cannot run Network Loopback test in diagnostics

Problem: In the Dos diagnostics utility, the user is unable to enable and run the Group 2 Network Loopback Test.

Solution: The Media Type on the 3C900-Combo is set to Auto by default in the configuration utility. Select and set the media type to On-board coax (BNC) (10Mbts). The group 2 test can now be enabled in Test setup.
