Troubleshooting and points to check when a network failure occurs.

Failure Point

Items to Check

What to Check

Physical Connection

Connection order.

In the case of normal network equipment, the connection work is the last step after setting the equipment, but this product is the first connection. When the wiring work is done at the end, enable the wired connection.

Check the cables connection.

Are you connecting the straight cable or cross cable by mistake? Are you using Category 6 or Category 5e cables?

Broken Cable

Connector claws are cracked or missing.
Can communication be restored by replacing the cable?

Network Interface, Gateway Settings

IP address. Subnet mask and default gateway settings.

Check network settings (IP address, subnet mask, default gateway).

Duplicate IP address

It is necessary to check whether the IP address set automatically or manually is not duplicated with other devices.

Security device settings.
DHCP settings.

When setting the IP address automatically, the IP address may not be set due to security products or DHCP settings, or the IP address may be deleted after a while even if the IP address is temporarily set. Sometimes.

Enable Wi-Fi and wireless settings (SSID, password).

Enable wireless settings.

Epson printers have one network setting, but wired and wireless settings are controlled exclusively. Check if changing the wireless/wired connection does not fix the problem.

Wi-Fi wireless standard matching.

Is the access point compatible with IEEE802.11b/g/n compliant 2.4 GHz, and are the network settings correct?

Encryption method setting, SSID/password0

Is the printer connected with the encryption method set by the access point, and is the SSID and password set?
