If your product has trouble finding or connecting to a wireless
router or access point (ES-C320W/RR-400W), try these
solutions:
- If you are
connecting the product via Wi-Fi Protected Setup (WPS), make sure
you activate WPS on your product within 2 minutes of activating WPS
discovery mode on the router by pressing the WPS button or enabling
the WPS setting in your router firmware.
- Make sure to
place your product within contact range of your router or access
point. Avoid placing your product near a microwave oven, 2.4 GHz
cordless phone, or large metal object, such as a filing
cabinet.
- Verify that
your router or access point is operating correctly by connecting to
it from your computer or another device.
- You may need
to temporarily disable your firewall and any anti-virus software on
your wireless router or access point. Then try scanning again. You
can also unblock your product driver or network address in your
firewall or anti-virus software.
- Check to see
if access restrictions, such as MAC address filtering, are set on
the router or access point. If access restrictions are set, add
your product's MAC address to your router's address list. To obtain
your product's MAC address, check the label on the back or bottom
of your product. Then follow the instructions in your router or
access point documentation to add the address to the list.
- If your
router or access point does not broadcast its network name (SSID),
follow the instructions that came with your product to enter your
wireless network name manually.
- 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.
- The product
may not be able to communicate with a computer with both Ethernet
and Wi-Fi adapters enabled. Disable all network interfaces except
for the interface connected to the product.
- Turn off all of the devices you are trying to connect to the
network. Wait about 10 seconds, and then turn on the devices in the
following order; wireless router, computer or smart device,
scanner. Move the scanner and computer or smart device closer to
the wireless router, and then try to make network settings
again.
- If you are using multiple wireless routers at the same time or
the wireless router has multiple SSIDs and devices are connected to
different SSIDs, you cannot connect to the wireless router. Connect
the computer or smart device to the same SSID as the scanner.
- Enable the DHCP function on the router or access point.
- Check that the product's IP address is set correctly.
- Make sure Epson ScanSmart is installed.
- If you cannot start scanning from a smart device, make sure the
product and smart device are connected correctly. Use the Epson
Smart Panel to check the connection status for the smart device and
the product.
