If your scanner has trouble finding or connecting to a wireless
router or access point, try these solutions:
- If you are
connecting the scanner via Wi-Fi Protected Setup (WPS), make sure
you press the WPS button on the
router or access point within 2 minutes of activating WPS on your
scanner.
- Make sure to
place your scanner within contact range of your router or access
point. Avoid placing your scanner near a microwave oven, 2.4 GHz
cordless phone, or large metal object, such as a filing cabinet.
Note: If you are
using a 5 GHz wireless router, set the router to operate in dual
band (2.4 GHz and 5 GHz) mode. If your router uses a single
network name (SSID) for both the 2.4 GHz and 5 GHz band, give each
band its own network name (SSID) instead, such as Home Network 2.4
GHz and Home Network 5 GHz. See your router documentation or
contact your internet service provider for instructions.
- Verify that
your router or access point is operating correctly by connecting to
it from your computer or another device.
- You may need
to disable the firewall and any anti-virus software on your
wireless router or access point.
- 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 scanner's MAC address to your router's address list. To obtain
your scanner's MAC address, check the label on the back or bottom
of your scanner. 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 scanner 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.
- If you
connected your scanner to a Windows computer using a direct Wi-Fi
connection and it automatically selected Access Point Mode, you may
have trouble accessing a low-priority Internet connection. Check
the network connection or adapter settings in the Windows Control
Panel and set the Internet metric
setting to 100 for your version of
the Internet Protocol.
- The scanner
may not be able to communicate with a computer with multiple
network interfaces. Disable all network interfaces except for the
interface connected to the scanner.
- Enable the DHCP function on the access point or router.
- Check that the scanner's IP address is set correctly.
