These settings are for setting up your wireless printer to stay connected to your router, keep wireless devices better connected and makes your router secure and hack proof.

While DHCP is convenient, devices such as printers should always be assigned a static (fixed) IP address manually to avoid conflicts on your wireless network.

1. Set a static IP in the printer (click here) outside the DHCP range of the router (check your manual). This is for Linksys routers but can be used for all routers. Verify your DHCP range and change this first if needed. More Wireless Printing help is here (Windows solution 4, static IP).
2. 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). Use the Embedded Web Server (EWS) by going to the printers IP address in your browsers address bar, click Settings Tab/Auto Off. Or use the Printer Assistant, Printer Home Page (EWS). Also check your Printers Properties.
3. If the printer supports and has IPv6 enabled, turn off IPv6 in the printer.
4. If needed and you assigned a static IP address, try using 8.8.8.8 for the Preferred DNS server and 8.8.4.4 as the Alternate DNS server. 
5. Wireless printers only work on the 2.4Ghz wireless band not the 5.0Ghz band.
6. Verify the printer is on the latest firmware by checking with the HP Support site.
7. Check all wireless devices in your home for interference. Check microwaves, baby monitors, wireless phones and wireless alarm systems are a big culprit.  Any of these will knock out your wireless printer intermittently.
8. Make sure your printer and router are at least 5 feet apart from each other.

In the router: (Refer to your router manual for information) 

1. Use a fixed wireless channel like 1, 6 or 11, never 'auto', try channel 1 first then the rest. 
2. Set router to 20Mhz only, or 145Mbps depending on router. 
3. Always use WPA2-AES (Personal) encryption, but you can try ‘mixed’ mode. 
4. Disable WPS and never use it and disable UPnP for the routers security. Nobody can hack your system now and helps with wireless connectivity (if you want to know why, search the web).
5. If you have a dual band router (2.4Ghz and 5.0Ghz bands), make sure the SSID’s are NOT the same, they must be different for all bands, even for any Guest networks.
6. SSID broadcast must be enabled.
7. Save all settings. Power off both, wait 2 mins.  Power on router wait 2 mins. 
8. Power on printer and verify it reconnects to router. 

Microsoft announced a Windows update to address device discovery ...waking up devices from sleep mode. Update your Windows 10.

https://support.microsoft.com/en-us/kb/3147458

If you have Windows 7/8/8.1   Is Network Discovery on or off?

1. Control Panel/Network and Internet/Network and Sharing Center/Advanced sharing settings.
2. Under Home or Work (current profile) / Network Discovery.
3. Select "Turn on network discovery" and save changes.

Now the last thing to do once all the above has been tried and you still have the same issue, fully de-install and remove the printer and all its software. 

Use http://www.iobit.com/en/advanceduninstaller.php .  Use Powerful Scan at the end to delete all registry entries.

Now go back and reinstall the Full Featured Software and Drivers from the HP web site.

Last ditch effort - If your printer has an Ethernet connection, suggest you get some Power Line Adapters and convert your house wiring to Ethernet for your printer.
