Having made the changes, you may need to uninstall and reinstall the printer. This will enable you to manually choose the least crowded channel in your router setup dialogue and also analyse signal strength at the location of the printer, which can also be an issue.
If you have an Android phone download and install Wifi Analyzer. By default, routers tend to be set to auto which then results in them using channel 1 or 6 automatically. Make sure the channel your router broadcasts on is not crowded. Sounds obvious but a surprising number or routers are setup with the two bands given the same name.ģ. On a dual band router, make sure your 2.4 and 5.0GHz are clearly differentiated by giving them distinct names: you need to connect to the same network that your computer is connected to. Make sure your wireless network setup is conventional: WPA2.Ģ. Working through HPs document ' HP Printers - Printer Does Not Maintain Wireless Connection' ( ) provides 12 steps and in the case of the 8720 it does work- but typically only when you get to the last steps.ġ. It's interesting to see that maintaining wireless printer connectivity is not a problem isolated to HP, virtually all the major makes (Epson, Canon, Brother etc) have postings from frustrated owners attempting to deal with drop outs and other connection problems.
This will cause the printer to drop offline and disconnect (yes verified!).Īdditional steps to be taken if you continue to have the problem (if they are posted)… Make sure printer is plugged directly into a wall outlet and not into a UPS, power strip or surge protector.If the printer supports and has IPv6 enabled, turn off IPv6 in the printer.Or use the Printer Assistant, Printer Home Page (EWS). Use the Embedded Web Server (EWS) by going to the printers IP address in your browsers address bar, click Settings Tab/Auto Off. Verify in the printer that 'Auto Off/Sleep/Energy Saving Mode' is disabled and/or the System Mode Time Out is set to zero (0).
Video here explains the problem and how to fix the problem. More Wireless Printing help is here and here and even more here. Verify your DHCP range and change this first if needed. This is for Linksys routers but can be used for all routers. Set a static IP in the printer (click here) outside the DHCP range of the router (check your manual).After setting the static IP, the computer must be updated under Printer Properties/Ports to show a Standard TCP/IP port with the printers IP address. While DHCP is convenient, devices such as printers (wired and wireless) should always be assigned a static (fixed) IP address manually to avoid conflicts on your wireless network and must be outside the DHCP range of the router. Keep all wireless devices better connected.These settings are for setting up your wireless (or wired) printer to:
