@ZUHAIRIT here's what you need to do:

(Follow the below steps for performing a hard reset)

1. Turn the printer on, if it is not already on.

2. Wait until the printer is idle and silent before you continue.

3. With the printer turned on, disconnect the power cord from the rear of the printer.

4. Unplug the power cord from the wall outlet.

5. Wait at least 60 seconds.

6. Plug the power cord back into the wall outlet.

      NOTE:

   HP recommends connecting the printer power cord directly to the wall outlet.

7. Reconnect the power cord to the rear of the printer.

8. Turn on the printer, if it does not automatically turn on.

9. Wait until the printer is idle and silent before you proceed.

Try to print. If the issue persists, continue to the next step.

These steps 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.

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' is disabled.  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 at the Alternate DNS server. 
5. Verify the printer is on the latest firmware by checking with the HP Support site.

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. 

Windows 7/8/8.1 & 10 - 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.
