• If your router or access point has security enabled, determine the kind of security it is using and any
required password or passphrase for connection. Then make sure to enter the exact WEP key or WPA
passphrase correctly.
• Check if your computer is restricting the available wireless channels. If so, verify that your wireless
access point is using one of the usable channels and change to a usable channel, if necessary.
• If you cannot connect your product to a device using Wi-Fi Direct, you may have exceeded the
maximum number of devices connected to your product (4). Print a network status sheet or access
Web Config on the browser for your device and check the number of connected devices. If 4 devices
are already connected, disconnect a device by deleting the product's SSID from the Wi-Fi screen of
that device. If fewer than 4 devices are connected, check the accuracy of your other network settings,
move your device closer to your product, and try connecting again.
• If you are using a Wi-Fi Direct connection that suddenly disconnects, the Wi-Fi Direct password on
your device may have been changed. If necessary, delete the existing DIRECT-xxxxxxxx connection
settings from your device and enter a new password. See your device documentation for instructions.

Network Software Cannot Find Product on a Network
If EpsonNet Setup cannot find your product on a network, try these solutions:
• Make sure your product is turned on and connected to your network. Verify the connection using your
product control panel.
• Check if your network name (SSID) contains non-ASCII characters. Your product cannot display non-
ASCII characters.
• Print a network connection report and check the codes and messages on the report to help determine
the cause of the problem.
• Make sure your product is not connected to a guest network.
• If necessary, reinstall your product software and try running EpsonNet Setup again:
1. Reset your product's network settings to their factory defaults.
2. Windows only: Uninstall your product software.
3. Restart your router following the instructions in your router documentation.
Note: If you are reading these instructions online, you will lose your Internet connection when you
restart your router, so note the next step before restarting it.
