Troubleshooting for Wired LAN connection

For Windows/macOS
Cause
A crossover cable is used.
There is a compatibility problem
with the hub.
Wired LAN (LAN1) settings are not
appropriate.
The optional wired LAN (LAN2) are
set incorrectly.
Both wired LAN (LAN1) and
optional wired LAN (LAN2) are
connected to the same network
segment.
Wired LAN settings are not
appropriate.
Depending on the network device
you are using, the connection may
become unstable if Energy Efficient
Ethernet (EEE) of the wired
network (LAN1) of this machine is
enabled.
When the optional wired LAN
(LAN2) is used, the optional wired

Check the wired LAN (LAN2) settings.
Although this machine can use wired LAN (LAN1) and
optional wired LAN (LAN2) at the same time, connecting
wired LAN (LAN1) and optional wired LAN (LAN2) to the
same subnet may cause unstable communication. To
stabilize the communication, set the IP address of a
different segment and connect it to a different network.
Only one of the gateway addresses from standard wired
LAN (LAN1), optional wired LAN (LAN2) and wireless LAN
is enabled. Select standard wired LAN (LAN1) or optional
wired LAN (LAN2) from [Admin Setup] - [Network Setup] -
[General Setup] - [Enabling Default Gateway].
Check if the switching hub supports Energy Efficient
Ethernet (EEE).
If it supports, change [Network Setup] - [Network
Connection] - [Wired (LAN1) Setup] - [Energy Efficient
Ethernet] to [Disable] from the web page of this machine
and check if it improves.
Set [Extended Network] to [Wired(LAN2)].
The optional wired module and the Wireless LAN module
cannot be enabled at the same time.
