Troubleshooting
■
Make sure there aren’t any access restrictions (such as MAC address filtering)
set on the wireless router or access point. If access restrictions are set, register
the printer’s MAC address on the router or access point. Print a Network
Status Sheet (see page 25) to obtain the MAC address. Then see your router or
access point’s documentation for instructions.
■
Check to see if your wireless router or access point is set to not broadcast its
network name (SSID). If so, you will need to enter the SSID manually (see
page 7). If your wireless router or access point has wireless security enabled,
you will also need to know what kind of security it is using.
■
Make sure that you entered the correct WEP key or WPA passphrase for your
wireless network. WEP keys are either ASCII or hexadecimal. If your WPA
passphrase contains upper- or lowercase letters, be sure to enter them
correctly.
■
If you see the message “The combination of IP address and subnet mask is
invalid”, try the following solutions:
■
If your router or access point is set to assign IP addresses using DHCP, try
setting the printer’s IP address setting to
Auto(DHCP)
.
■
If you want to manually configure the printer’s IP address, click
Change
when you see the Current IP Address Status screen and enter the IP
address and subnet mask.
■
Make sure your computer is connected to your wireless router or access
point. See your router or access point’s documentation for details.
■
Set a unique IP address for your printer. All IP addresses are written in
segments of four numerical values. The last segment must be set to a
unique numerical value (between 1 and 254). When the router is set to
assign IP addresses using DHCP, set the printer’s IP address to a value that
doesn’t conflict with the IP address range assigned by the DHCP server.
For example:
IP address of your router or access point: 192.168.1.1
IP address of your printer: 192.168.1.3
For the subnet mask, 255.255.255.0 is normally used for small-scale
networks (all devices on your network should use the same subnet mask).
Also, when a gateway value is set, use the same value as the IP address for
your wireless router or access point.
