Intermittent wired network connection on HP OfficeJet Pro 8600

I've searched the forums and I haven't seen a problem/solution quite like I am experiencing, so I am starting a new thread.
I have a HP OfficeJet Pro 8600 that will only keep an intermittent connection to my router. Lately, it has been more often not than connected. I usually have to disconnect and connect the Ethernet cable to the back of the printer several times before it will show a connection, and then, only for a little while before it drops the connection again. When connected, everything works fine (printing, faxing, scanning).
When the printer is disconnected, the network status has a yield sign with an exclamation point inside. There are no blinking lights on the back where the network cable connects. When it connects (by me plugging and unplugging), the lights start flickering. I've tried several cables including known good ones to rule that possibility out. Cycling the power has no consistent affect. The router is otherwise working fine.
Here are other details that might help:
Model: HP OfficeJet Pro 8600 (N911a)
Firmware: up-to-date
Software drivers: up-to-date
Router: CISCO E3200
Connection: wired network
Static IP address reserved (not connecting with DHCP)
MAC filtering off
Main Computer: Windows 7 Service Pack 1
Wired Connection to the router
Can someone suggest a solution? My best guess is that the network card in the printer is bad, but I am willing to try an easier solution. Thanks.

Hi, are there any other peripherals using the RJ45 ports on the router?
Are you using a static IP address for the 8600?

Intermittently having issue sending scans to networked directory folder HP Officejet Pro 8600 N911g

Hello All,
I have a printer installed an AIO HP Officejet Pro 8600 N911g which is cappable of scanning either by flatbed or feeder to a networked drive/folder. For the most part this works fine, however 2 times out of 10 it produces the following error;
"Cannot connect to \\'Server details\Folder location path'. Make sure the remote computer is turned on."
Now I have seen many post about disabling the filewall and other, however none of this type after an install.
Some obvous checks have been made already, Network cable replace, Changing of the destination folder location, and reseting the password for the scanner to auth as well as confirming the permisions. And each time the tests via the web console and physical tests work fine though this doesn't last.
Could anyone help?
Thanks

Hi @Paperjam27
From your description, it sounds like the issue is intermittent. It can sometimes be challenging to identify the root cause of an issue when the problem is not consistent, but I am happy to work with you towards a solution. I suspect the issue might have something to do with the network. I know you said you have tried a new cable and done some troubleshooting already but bear with me here.
When you say you replaced the cable, do you have an Ethernet cable connected between the printer and the router? if not, then I wonder if there is some sort of interference on your wireless connection. Is your router is a dual band router broadcasting both 2.4 and 5.0 frequency? The printer only works on 2.4GHz, maybe this is the root cause.
The channel your router is set to can impact your network consistency too. For example, if you are on channel 11 and others in your area are also on channel 11 or even 9 or 10 it causes congestion on that channel. Think of the channel like a highway or interstate, the more cars on that highway/interstate, the slower you go due to congestion, if you are on a highway with less people are on it, it is more like smooth sailing! You can print a network configuration page to see what channel you are using and see what channel others in your area are no. If the higher channels are most common you might consider changing yours to 1, 2, or 3, and visa versa. How to: Printing a Network Configuration Page.
has this ben an issue since you have had the printer or did it recently start happening? If this only recently started, can you think of anything that changed recently? Do you have only one access point (router) or do you have a secondary router or extender? Can you think of anything that might be interfering with your network, and do you find the issue occurs more at a certain time of the day than others?
I found on my network at home, I was often seeing delays in response time in the early evening because others are coming home from school and work and 'clogging up the channel', I changed the channel and have had little to no issue since.
Let me know if you think of anything, and post back with the answers to the questions I have posted and I will get back to you. Thanks.

HP Print and Scan Doctor can't connect to HP Officejet Pro 8600 Plus.

My HP Officejet Pro 8600 has been working perfectly for the last 1+ years, up until 2 days ago, when it stopped printing jobs submitted from my Windows 7 desktop. I've tried all manner of repair, thus far unsuccessfully, including
resetting the IP on both the printer and the desktop
trying wireless connection, no difference
reinstalling drivers and firmware
hard-resetting the printer
repeatedly trying to print test pages
repeatedly restarted the Print Spooler, and rebooted the desktop
attempting to troubleshoot using HP Print and Scan Doctor.
Additional facts:
My wife can use the printer from her work laptop without any problems.
I can ping the printer from the desktop at its static IP, so IP-level connectivity isn't the problem.
The standard print queue view indicates "(Offline)" in the title bar, and attempting to print a test page from the Properties dialog submits the page, then Status flips to "Error - Offline - Printing", despite the fact that the Properties dialog shows no checkmark next to Use Printer Offline menu entry.
The Doctor finds the printer at its IP and acknowledges that it's installed, and when asked to Fix Printing, says that everything checks-out okay with the product. However, when I ask it to Test Print, it comes back with a pop-up stating it's Unable to Communicate with Printer; it suggests "Click Help for additional assistance information.", but there's no Help button.
If you've experienced this printer in a similar firmly-wedged state, I'd deeply appreciate hearing how you fixed it.
Thanks,
-Richard (Personal information)

Hi @Sunshyn2005
I timed-out waiting for advice, and contacted HP Support, who helped me get the printer back on the air. While we didn't manage to root-cause it, in the course of trying various things, the tech disabled Norton 360's firewall, which then allowed connecting to the printer, and restoring print service, which remains up after re-enabling the firewall.
The timing of the disconnection doesn't neatly corellate with any Windows updates. My own theory is that it was caused by a 360 update, but am unable to find a smoking gun, since 360 doesn't provide update history. The exact root-cause remains a mystery, but at least provides another thing for folks to try should they find themselves in similar straits.
I really appreciated your hint that a Windows update might be the root cause, and your pointing out how to review the history and back-out updates: this morning, I found that Windows had installed a batch of updates overnight, and found that no browsers worked. Using your advice, I rolled back the update, restoring browsing.
Thanks,

Intermittent wired network connection on OS 10.3.9. Help!

Hi,
   I'm having some issues on our home network with a G4 / 933 tower that is connected to our wireless router via an ethernet cable. We also have a Powerbook G4 15" (running 10.4.1) connected via Wi Fi, as well as a new brand new iMac connected via Wi Fi. The router is a D-Link DIR 825 Dual Band that we inherited recently as a hand-me-down.
The router is setup using DHCP. The two computers connected via Wi Fi have virtually no problems. However, ironically, the G4 tower, that is connected via an ethernet cable, is constantly losing it's internet connection. It's very weird (For what it's worth, up until January, this same computer was connected directly to a DSL modem at a different location via ethernet, and had no connectivity problems, ever...) When you bring up a browser - Firefox, Camino, Safari - it will work for a minute or two, then suddently if you try to go to another page it will say "Waiting for..." And you wait, and wait. If you try to go to another location it will say "Looking up...", as if it's completely lost it's DNS capability, which it seems it has. However, if you wait a few minutes it comes back. But with annoying regularity it will die again, then you have to wait 1 - 5 minutes for it to come back. Going to Network and clicking "Renew DHCL Lease" doesn't seem to bring it back any faster than just waiting. I've also tried different ports on the router. Whenever it loses it's connection, if I go to the Network settings area, it will display a green light and say "Connected to the internet via Ethernet". So the physical connection still seems to be there.
   It's very frustrating. Is it an IP conflict issue? Shouldn't DHCP handle all that? Maybe a problem with Computer Names? Any troubleshooting tips would be appreciated! Thanks

Hi,
   Thanks for the response. Yes, I did install a brand new ethernet cable. I also tried shutting down our other two wired computers so the wired G4 was the only computer on the network. Still no luck. I also tried reserving an IP within the DHCP range just for the wired G4, and setting the Network Preferences to Static IP w/ DHCP. Still no luck. I'm starting to think it's just a piece of crap router and I should just try a new one. It doesn't really make any sense, because it's not rocket science. And the wireless computers work perfectly...
   Does anyone have any other things to try? Or barring that, any suggestions for a solid, reliable wireless router? Thanks - Steve

HP Officejet Pro 8600 Plus Not Recognized On The Network

I have a CenturyLink DSL Modem/Router that has 4 ports on the back. I use Port 1 on the DSL Modem/Router to conntect to my NetGear Router. I use Port 2 on the DSL Modem/Router to connect my HP OfficeJet Pro 8600 Plus printer. I use Port 3 on the DSL Modem/Router to connect my Brother MFC-7360N printer. I am not using Port 4 of the DSL Modem/Router.
My NetGear Router is used to connect all wired desktop PC's (5) in the house.
I was able to successfully install the software for the Brother printer on all computers and can print on the Brother printer from any of the desktop pc's.
I have the software for the HP printer installed on all computers but on the WIN XP desktop pc I cannot detect the printer on the network. During the setup process the software detects that the HP printer and the WIN XP pc are connected to two different routers (the DSL Modem/Router is being detected as a router by the WIN XP pc). On the other desktop pc's which are running either WIN7 or WIN8 there is no detection problems even though the printer is connected to the DSL Modem/Router while the PC is conntected to the NetGear Router.
Does anyone have any knowledge as to why I am having this problem. The problem seems to be only with the WIN XP pc and not with the WIN7 or WIN8 pc's.
This question was solved.
View Solution.

You are running a double NAT scenario, not good. Simple fix, put the gateway unit (modem/router) in bridge mode, which will disable the router functions and just make it a modem. Now connect the Netgear router to the gateway unit and have this handle all your wired and wireless connections.

Connecting HP Officejet Pro 8600 to Verizon JetPack 4G-LTE

Hi, as you can probably guess I am trying to connect my HP Officejet Pro 8600 to my wireless Verizon hotspot. I have tried to use the "Wireless Setup Wizard". When prompted I chose the correct network, and entered the correct password. After some time the printer displays:
Connection Successful
IP: No Link
Network Name: Not applicable
followed by a Hostname and the MAC address of the printer. When I try to view the wireless connection the window states that I am not connected (as suspected). I then printed the "Wireless Network Test Results". It reports "No problems found. Congratulations on the successful setup of your wireless printer." and everything under the "Diagnostics Results" section passes. Under the "Current Configuration" section the correct SSID is displayed, however the IP address comes up as 0.0.0.0 (which means I am not connected?).
Also, I checked the Jetpack's configuration page and the MAC filtering is disabled.
Is it possible to connect this printer to a Verizon Jetpack (MiFi)? If so, what am I doing wrong?
This question was solved.
View Solution.

It looks like the printer is connecting to the network, just not receiving any IP information.
I will provide the simplest solution that typically resolves this issue. To receive the best results, be certain to follow them in order.
1. Power off the JetPack.
2. Disconnect the power to the printer while it is on for 1 minute.
3. Power on the JetPack and wait for the network connection to come back up. This can be easily identified when other devices start connecting to it again.
4. Reconnect the power to the printer and wait for the home screen to finish loading.
5. Press the antenna icon and select Settings.
6. Scroll down and select Restore Network Defaults.
7. Once that is completed, reconnect the printer to the network with the Wireless Setup Wizard.
DHCP, dynamic host configuration protocol, is responsible for assigning IP information to devices automatically as they connect. It is possible to connect to a network without DHCP, there just won't be any communication unless IP settings are set manually.

Utilizing both wired network connections

Hello,
Is it possible to utilize both wired network connections on a Mac Pro? What I need to do is connect 5 Mac Pro computers to each other via a Cisco switch and use file sharing to connect between them and transfer files. Also, the other network connection needs to be connected to our corporate network - email, internet, connecting to servers not associated with the other network connection. The second network connection is already in place, and I need to now connect the 5 Mac Pros. How do I set this up in OS X? Is it possible? Thanks.

Hi RoyJames,
What type of device are you trying to connect to the printer? It is possible to have the printer connected via USB for one device and connected via network for another.
Hope this helps.

HP Officejet Pro 8600 All in One printer - printing wirelessly from an IPAD

I'm trying to connect a HP Officejet Pro 8600 to our university campus wireless network for the purposes of printing wirelessly from an IPAD. The printer finds the wireless network when going through wireless wizard setup but gets a message that the wireless network is using security that is not supported.
The campus wireless network uses:
Security type: WPA2-Enterprise
Encryption type: AES
Can anyone tell me if these are supported by this model printer?

Hey ibebry,
The printer is designed to be used with WPA2 - Personal and not the Enterprise version. From the wiki artricle on WPA encryption:
WPA-Personal Also referred to as WPA-PSK (Pre-shared key) mode, it is designed for home and small office networks and doesn't require an authentication server. Each wireless network device authenticates with the access point using the same 256-bit key generated from a password or passphrase.
WPA-Enterprise Also referred to as WPA-802.1X mode, and sometimes just WPA (as opposed to WPA-PSK). It is designed for enterprise networks and requires a RADIUS authentication server. This requires a more complicated setup, but provides additional security (e.g. protection against dictionary attacks on short passwords). An Extensible Authentication Protocol (EAP) is used for authentication, which comes in different flavors.
If the network is using WPA-Enterprise, then most likely the 8600 will not be able to connect. Hope this helps.

HP Officejet Pro 8600 Plus (UK purchase) will not connect to wired ethernet network

Hi
We have an HP Officejet Pro 8600 Plus (purchase here in UK approx 9-12 months ago) which has sort of worked OK wirelessly but finance industry compliance requirements now require me to connect to it by normal ethernet cable.
When I disable wireless and plug in a (tested and working) ethernet cable it does nothing. I have done a factory reset (via the screen menu) to remove any previous settings. Turned off, turned on, still nothing.
I have restored Network defaults also using the menu command within settings - network; no difference.
In Network - wired summary the screen says:
IP: Not applicable
MAC: xxxxxxxxxxx (not for sharing here)
Hostname: xxxxxxxxx (not for sharing here)
Wireless Direct: Off
I have tried it with IP settings turned to Automatic (DHCP) - no joy.
I have tried it with IP settings turned to Manual(Static) - when i then type in the static IP address that is within the router range (but outside the DHCP reserved range) as soon as I press Done, the settings are lost i.e. 192.168.0.102 - push 'Done' and the IP goes back to 000.000.000.000
The same when entering the default gateway and subnet masks.
I have restored to defaults several times, tried manual and DHCP several times, no joy.
Please let me have some serious suggestions at the earliest opportunity. Just to reiterate I have tested the network connection and cables with other ethernet equipment and they are working. My questions include:
1. Anyone know how to make this printer actually store the manually entered IP addresses etc?
2. What am I missing about the wired setup?
3. Is this a known issue? Is it an issue with the hardware ethernet socket or something?
4. Also in this forum there are references to a Hard Factory reset that is apparently different to the menu 'Reset to Factory Defaults' but links to an article about it just give a 404 error, not found. [Does HP actually have two different levels of Factory Default and if so, God knows why! Does anyone know a working link to this information please?

Hello Qw8, welcome to the forums!
I read your post about not being able to successfully install your Officejet 8600 Plus to your wired network. I will do my best to find suggestions for you to try. I would first like to know which Operating System you are installing the printer on to help me with my research.
If you haven't already, run the installation (HP Officejet Pro 8600 Plus e-All-in-One Printer - N911g Drivers) with your security and firewalls disabled to see if the proper connection can be made.
I do see you ask about other resets and there are others however, at this stage they may not be needed. If they are, I can send you a private message at that time with that information.
Please let me know your OS and we will go from there!

Scan To network folder - HP officejet pro 8600 cannot connect.

Good morning,
For the last week or so, My officejet pro 8600 has been giving me the error
"Cannot connect to \\REDACTED\Public\Scans. Make sure the remote computer is turned on."
It will correct itself if we restart the computer/printer in question. but this only solves the issue for approx 6-7 hours.
Things i have done to attempt to fix this.
Set a static ip address for both the computer in question and the printer itself.
updated the IP address using the HP tool.
reinstalled the HP office program.
Set DMZ for both the computer and printer.
Set the public scans folder to zero security( so anyone connected to the network can gain unrestricted access)
re-setup the network feature on the printer itself.
however now i am at a loss.
Any help would be great.

HP Officejet Pro 8600 Network connection error message in EWS

I just got an Officejet Pro 8600 Premium. The printer is connected to the network via a network cable. When navigating through the EWS, sometimes the message "Network connection error. Check network and try again." message is shown (the message could appear in various pages, such as Settings, Tools, etc.). Refreshing the page should get rid of the message.
At first, I suspected if it was a problem with the network. So I pinged the printer's ip address continuously. It did not miss a single beat. The printer prints and scans well via the network. So I think the error may be caused by something inside of the print, such as bug of EWS software, or internal error.
Anyone see the same message during the use? Any suggestion? Does it indicate there is hardware problem with the printer? Thanks.

HP Support has escalated the case. I referred this thread in the support request. Hopefully, they can have a look at the issue.
For me, the only setting does not stick is "Use the same time zone set on this computer" in Settings\Date & Time. I've created another ticket for this issue. 8500A has the same problem.
You can try to restart the EWS. Unplug the power cord while the printer is on. Then wait 15 sec and reconnect the power cord. Press the power button if the printer does not turn on by itself.

Wireless Printing to OfficeJet Pro 8600 Connected to Ethernet Network

We have an OfficeJet Pro 8600 that is connected to our home's Ethernet network and would like to print to it from devices such as laptops, phones, and tablets. Any attempt to turn the printer's wireless capabilities on results in a command to disconnect the Ethernet cable, which we would prefer not to do.
Is there any way to "have our cake and eat it too", retaining the Ethernet connection while having the ability to print wirelessly? While useful, HP's ePrint doesn't offer the direct-from-application convenience we desire.

Hi,
By the book, the following setup should work:

Officejet pro 8600 will not connect to wireless network

I have an new Officejet Pro 8600 that I am trying to set up. I have run the the wireless network setup wizard multiple times. It recognizes the wireless network router asks for the WEP code and then thinks for about 5 minutes before returning a message: "Unable to connect to the network"
The wireless network test results suggestes that MAC address filtering may be the problem. There is no MAC filtering function activated on our wireless router.
The wireless router is a Verizon Actiontec MI424-WR 802.11 b & n
We have computers running both Windows XP and MAC OS X.
One of the reasons that we purchased this printer is for the wireless capabilities. If it will not conect to the web then it may be going back.

Hello,
Based on the provided details, I believe the issue have something to do with the wireless security settings of your router.
Please follow the steps below to access the Advanced Security Settings:
http://www22.verizon.com/ResidentialHelp/FiOSInternet/Networking/Setup/ActiontecMI424/125511.htm
Below you will see the Network Authentication settings.
Select either Open System Authentication or Both.
Shared Key Authentication is not supported by the printer, and i believe this might be the cause for the connection failure.
Please let me know of any change,

Officejet Pro 8600 Plus connection issue - HELP!

I have a strange issue: after some hours, the communication link is dropped between the computer and printer. When this happens, IE becomes unusable and will not connect to anything. This is replicated on three XP home machines. The fourth, a vista ultimate machine, does not seem to be affected (yet). I get the "scan to computer is disabled" error. It cannot be re-enabled. At this point I cannot print either. I can reach the embedded web server on the printer via firefox and can still surf using firefox. I can ping the printer, but again once the connection is dropped, no printing or scanning to the computer. The only thing I've found that resolves the issue (temporarily) is to reboot the computer, which just starts the cycle again.
last night I installed the software on an XP machine and the laptop to test when the connection dropped. They lasted from 7pm Monday until I got home at 5pm Tues. The machines were not used. Once I started using them (firefox only), then they dropped the connection within a half hour of each other around 7pm. The other XP machine lasted from 7pm Mon until 7am tues, when my wife started using it and then noticed it dropped sometime that tues between 7 and 9AM. An 11am tues reboot ran OK until 10 pm tues when connection was lost again (and IE is now dead). The Vista machine has been running since 7pm monday until now (930pm tues) and still seems to be holding.
printer hardwired, to router, static IP, 100-full link speed (also tried 10-half)
router dlink di-655
two XP machines are hardwired, vista is hardwired, and last xp machine is a laptop on wireless.
I've swapped cables rebooted and reinstalled multiple times. I must have a file a mile long on the support phone line. They were unable to fix it. I asked this to be escalated, but who knows when I'll get a response.
I've toggled firewalls - XP built in
I've uninstalled anti virus software
I've even put up with crazy suggestions from tech support like changing the router channel (uhh, it is wired!)
one xp machine had an AIO 4215 hooked via USB and the others printed to it via network, but the printer has been deleted from the networked machines.
I can ping 127.0.0.1 which is supposed to indicate the tcp service is OK.
I have not reset winsock .. I can see one machine being bad, but three????
malware / virus scan shows no issues. Again one maybe, but three??
The only thing I can think of is that there is something in the XP networking stack that conflicts with the new 8600 software as hours pass. Perhaps there is some polling operation that goes on then dies after some time, then it kills IE as it dies.
When the printer works it is great, but rebooting is not a permanent solution to this.
any suggestions would be greatly appreciated!!!!!! I am stumped and so is tech support. They are sending it to engineering, but who knows when they will respond.
thanks in advance.
This question was solved.
View Solution.

well it looks like I have a working solution ... I downloaded a freeware file called process.exe . I made a cmd file via notepad with the following contents:
rem this is to keep the HP network printer communicating with the desktops
rem
process -k "hpnetworkcommunicator.exe"
rem
process -k "scantopcactivationapp.exe"
rem
"C:\Program Files\HP\HP Officejet Pro 8600\Bin\HPNetworkcommunicator.exe"
rem
Start "" "C:\Program Files\HP\HP Officejet Pro 8600\Bin\ScanToPCActivationApp.exe" -deviceID CNXXXX:NW -scfn "HP Officejet Pro 8600 (Network)"
the XXXX is your printer serial number with an extra character or two. Pull that number from the port tab after you pull up "properties" for the 8600 printer.
This cmd file basically restarts the printer link. It opens a command window that launches the program to re-establish the link.. then it closes the command window. The launched program shows that the communication link is dead (just for a few seconds), but then it makes the connection... THEN you hit the close button and coninue your work until it dies again.
I may have it autorun every X hours if I can narrow down a good time. Until then I have a shortcut on the desktop to "FIX HP LINK" ... I only had to do this for my XP machines, as the vista one seemed OK.
What ticks me off is that I shouldn't have to do all of this diagnosis. It would be nice if there is a fix in the pipeline so the link stays stable al the time. I've spent hours trying to figure this crap out.
Anyhow, I hope the time I spent helps someone. PS, thanks to the OJ6500 thread that had the info for the scantopcactivationapp.exe program.
PS ... I'm still waiting for an engineer to contact me, if any HP employees are reading this.
PSS I haven't tried this without killing and restarting the hpnetworkcommunicator stuff, but it works for now.
