ELIMINATE SOURCES OF INTERFERENCE
Common household items can potentially disrupt wireless ne twork communications. Cordless phones (but not
cellular phones), microwave ovens, baby monitors, almost any kit chen appliance, wireless surveillance equipment,
nearby wireless networks, and any appliance containing a motor can disrupt wireless network communications.
Try turning on any potential sources of interference and see if it causes the problem. If it does, separate your wireless
network from the device.
CHANGE THE CHANNEL THE WIRELESS ROUTER USES
You can sometimes eliminate interference from unknown s ources by changing the channel your wireless rout er uses
to broadcast. There are three distinct channels on a router. Chec k the documentation that came with your router to
determine which three apply. Other channels are offered as options , but these overlap. If the router is configured
to use the default settings, change the channel setting to use a different dist inct channel. Refer to the manual that
came with your wireless router if you are not sure how to change the c hannel.
CONFIGURE THE WIRELESS ROUTER WITH A UNIQUE SSID
Many wireless networks use the SSID that the router was originally co nfigured by the manufacturer to use. Using
the default SSID can cause problems when more than one network is operating in the same area with the same SSID.
The printer or computer may attempt to attach to the wrong network, although it will appear to be trying to connect
to the correct network.
To avoid this type of interference, change the SSID on your wireless router from the default. Refer to the manual
that came with your router if you are not sure how to change the SSID.
Note: You must change the SSID on all of the other devices that acc ess your wireless network if you change the SSID
on the router.
ASSIGN STATIC IP ADDRESSES TO ALL DEVICES IN THE NETWORK
Most wireless networks use a DHCP server (dynamic host conf iguration protocol) built in to the wireless rout er to
assign IP addresses to clients on the wireless network. DHCP addresses are assigned when they are needed, as when
a new device is added to the wireless network or when it is powered on. W ireless devices must send a request to
the router, and receive an IP address in response so they can function on the network. Because the router performs
many other tasks besides assigning addresses, it sometime s does not respond quickly enough with an address. The
requesting device sometimes gives up before it receiv es an address.
Try assigning static IP addresses to the devices in your network to resolve this issue. Static IP addresses cut down on
the work your wireless router has to do. Refer to t he manual that came with your router and your operating system
documentation if you are not sure how to assign static IP addres ses.
To assign a static IP address to the printer, do the following:
1Complete the wireless setup, allowing the printer to receive a DHCP address from a DHCP server on the network.
2Print a network setup page to see what IP address is currently assigned to the printer.
3Open a Web browser and then type the printer IP address in th e address field. Press Enter.
The printer Web page loads.
