M252dw Keeps Dropping Off Network

[Canprof]

I have just unpacked a brand new M252dw.  I connected it successfully to my wireless network.  But as soon as it is connected, it drops off the network and is not visible to the computer or router.  If I power off and on, it becomes visible for a few minutes, then disappears.  Even when it is off the network, the status shows it as connected.  The IP is valid (192.168.2.72) and I've reserved the IP in the router so it will never change.  The signal strength is full.  The Network Configuration Summary does not show any other networks in the area.  The gateway is correct (192.168.2.1). 

There is a "Run Wireless Test" menu option.  If I try that, it says "Running Test", then it says "Printing Document", then it stops.  It never prints anything.  The display never clears unless I power off and on.

If I try the "HP Scan and Print Doctor", it won't work because it can't find the printer.  If I power the printer off and on then immediately run the Doctor, it says the printer is working fine.

My network settings have network discovery on; auto setup of network devices on, and file and print sharing on.

I suggest assigning the printing a static IP address.

As I said in the original post, I already did that.  The IP shown on the printer disp[lay and on the router exactly match and never change.

Hello,

Did you ever solve this issue?  I'm having the exact same problem when trying to print to my M252dw.  Just opened it literally a couple hours ago and noticed that it drops Wifi connection after sending a large document to the printer.  I have installed the latest firmware and have tried assigning a manual IP address, but no luck.

Any ideas?

Same issue here, only I have it on a wired network. It worked OK at first, but I did not print a lot, only 1-2 pages at a time. Then I needed to print like over 30 pages; it prints a few then stops, then a few more, then stops, then wouldn't print anything at all. The message on LCD display says Printing... and stays like this until reset.

I gave up on the wireless.  It works fine on wired.

I never solved it, even after hours on the phone with HP.  I gave up on wireless.  It seems to work fine on wired.

Obviously HP has a problem with the driver and hasn't acknowledged it or solved it.

You set a reserved IP in the router. You need to set a static IP in the printer. They are not the same thing.

I know they're not the same.  I kept checking the IP at the printer and it remained the same.  Nonetheless, I also tried setting the static IP in the printer but it didn't solve the problem.

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.

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 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 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   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.
