Our wireless printer loses communication

You are losing contact because you are losing your IP address for the printer. Do this:

Click on start>run>type in "cmd">then go to c:> prompt by typing cd\. Type ipconfig /release then type ipconfig /renew. This will re-establish your IP address for the printer and will not change for 24 hours. If you lose your contact after 24 hours then you need to contact your Internet Service Provider, tell them that your DHCP server is not renewing your IP address. There is nothing else that can be done on your part. The ISP provides the IP address.
