“Communication not available” message displays when printing wirelessly
These are possible solutions. Try one or more of the following:
MAKE SURE YOUR COMPUTER AND PRINTER HAVE VALID IP ADDRESSES FOR THE NETWORK
If you are using a laptop and have power saving settings enabled, you may see the ”Communication not available”
message on your computer screen when you attempt to print wirelessly. This can occur if the laptop hard drive
has powered down.
If you see this message, wait a few seconds and then try...

Temporarily turn off any unnecessary wireless devices on your network and pause any network-intensive
activities, like large file transfers or network games. If the network is too busy, it is possible that the printer is
not receiving the IP address within the allowed time.
Make sure your DHCP server, which may also be your wireless router, is working and is configured to assign IP
addresses. If you are not sure how to do this, refer to the manual that came with your wireless router for more...

Resolving intermittent wireless communications issues
You may notice that your printer works for a short time and then stops working, although apparently nothing has
changed on your wireless network.
Many different issues can interrupt network communications, and sometimes more than one problem exists at the
same time. These are possible solutions. Try one or more of the following:
DISCONNECT FROM ALL VPNS WHEN ATTEMPTING TO USE THE WIRELESS NETWORK
Most Virtual Private Networks (VPNs) allow computers to...

CONFIGURE THE WIRELESS ROUTER WITH A UNIQUE SSID
Many wireless networks use the SSID that the router was originally configured 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....

CHECK FOR WIRELESS ADAPTER UPDATES
If you are having trouble printing from one particular computer, check the Web site of the manufacturer of the
network adapter card in that computer. It is possible that there is an updated driver available that could resolve
the issue.
CHANGE ALL NETWORK DEVICES TO THE SAME TYPE
While it is possible to successfully mix 802.11b, 802.11g, and 802.11n devices on the same wireless network, the
faster devices will sometimes prevent the slower devices from communicating....
