Running the Group 3 Test

The Group 3 test is the Echo Exchange Test. It tests to see if
the NIC can transmit and receive data while connected to
the network. If you have successfully run the Group 1 and
Group 2 tests, a failure in the Group 3 test usually indicates
a cabling, hub, or network problem.
CAUTION: Do not use an active network to run the
Group 3 test.
