If your scanner has trouble finding or connecting to a wireless
router, try these solutions:
- If you are
connecting the scanner via Wi-Fi Protected Setup (WPS), make sure
you activate WPS on your scanner 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 scanner within contact range of your router. 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. Be sure to
connect your scanner only to a 2.4 GHz network name
(SSID).
- Verify that
your router 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. Then try scanning again. You can also unblock
your scanner 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. 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 documentation to add
the address to the list.
- If your
router 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 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 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.
