Check the setting
Are the network settings of this unit correct?
Are peripheral devices such as the router and hub
connected to this unit correctly?
Are the router settings correct?
Set the IP address, etc. correctly.
When the static IP address is used, check that no
other devices have the same IP address and that
the subnet mask settings are correct.
Connect the peripheral devices correctly.
Check the instruction manual of the router and
congure the settings correctly.
Check that there are no connection restrictions by
MAC addresses, etc.
Is the LAN cable correctly inserted?
Insert the LAN cable correctly and then turn on
the power again.
Check the connection environment
Checking the unit
The circuit of Network Module is faulty.
Are the versions of the HEOS Version displayed in
Version Check Mode?
