If your product has trouble finding or connecting to a wireless
router or access point (DS-80W), try these
solutions:
- If you did not successfully connect to a network while
installing your product software, select the link at the end of
this topic and follow the steps in "Manually Connecting to a Wi-Fi
Network."
- 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.
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 computer and scanner only to a 2.4 GHz
network name (SSID).
- 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.
- Enable the DHCP function on the router or access point.
- Check that the product's IP address is set correctly.
