Explanation
The code has detected more than one MAC address
though the connection, or the DHCP has given out more than one address.
The code thus believes there is a switch attached.
User Response
- Plug a cable from the technician port to a switch, and plug 2
or more machines into that switch. They must have IP addresses in
the range 192.168.0.1 - 192.168.0.30
- Request a DHCP lease to trigger the detection.
