HP Color laserjet CP3505n loses network connections

My HP Color Laserjet CP3505n used to print flawlessly from 2 computers wired on my network. Now sometimes it says connected, but hangs up when trying to print. Or sometimes it says OFFLINE. Either way, I end up with a queue waiting to print and nothing happens. If I turn off the printer then turn it back on, it will bring the queue, but only will recognize the network for a minute or two. I have a Verizon GT704WGB wireless router, but all of my other network devices work perfectly.

HP Color LaserJet CP1520nw will not connect to network (time out repeatedly)

My HP LaserJet CP1520nw won't connet to my wireless router upon installation, no many how many times I've been asked to connect it to the computer via a USB printer cable. I uninstalled and reinstalled all software, and each time I try to set it up for wireless connectivity by connecting my computer and the printer via a USB printer cable, it gets to 99% installed on the progress bar and sits there until it times out. I suspect one of the follow but am open to other ideas from those more knowledgeable:
1. Is the printer locked onto some old, initial configuration from a previous wireless network that needs to be purged of addresses, etc. before it can accept the new ones?
2. Could my WPA WPA2 PSK AES encrytion be messing it up? Are the modern firmware and updates designed to accept these ? I never have gotten to a screen where it asks for my encyption key or even a WPS pass phrase. What to do if so?
3. Could Church Lady be correct and that it is Satan preventing the installation? If so, what icons does he use to watch out for and will my Norton anti-virus and malware quarantine him to Hell automatically or does it require manual enforcement?

Hi @Marvalina1968,
Welcome to the HP Forums!
I noticed that your HP Color LaserJet CP1520nw will not connect to network with Windows 7. I am sorry to hear this, but happy to help!
First to answer your questions:
It is possible the printer could be locked to an old configuration and needs to be reset.
I don't think your WPA WPA2 PSK AES encrytion could be messing it up, unless you got some really strange characters in your password.
Your Norton antivirus, could possible be causing the installation to fail.
Please take a look through the following guides:
'Printer is offline' Message Displays on the Computer and the HP Printer Will Not Print.
Printer Does Not Maintain Wireless Connection.
If the guides do not resolve the issue, please try the following:
Uninstall the software. Uninstalling the Printer Software.
Clean boot the computer. How to perform a clean boot in Windows.
Disable any antivirus programs. Disable antivirus software.
Disable any firewall programs. Turn Windows Firewall on or off.
Re-install the software. HP LaserJet Full Feature Software and Driver.
Hope this solves your problem, and have a good day!

E4200 - Plug in external USB drive & lose network connection

Hi - I have the Linksys E4200 [version 1] and my wireless network is set up and configured. I'm browsing with no issues. Within Linksys setup, FTP & UPnP are enabled. I have a 500GB Toshiba external USB [2.0] hard drive [E05A050DAU2XM]. When I connect it to the E4200 the data light on the modem goes off within 10-20 seconds & I lose network connection. I've tried leaving the drive plugged in and rebooting either/both the cable modem and the router but network connection is not restored until I disconnect the drive & power cycle the router. Not sure what is happening. The modem is a Cisco DPC3010 DOCSIS 3.0. I should also say that this was happening with, I believe, firmware version 1.0.01. I updated to Ver.1.0.06 (build 3) & the issue is still occurring. Thanks so much for anyone who could lend their advice!

It maybe a drive size problem that maybe the problem and not compatible. If a smaller size drive works and the larger does not. then this could be the issue. I don't recommend any drives over 500Gb to 1Tb on the USB. The larger the drives are the more problematic the issues can be and should a drive become full, the longer processing of the information will be come and USB is not the best performance for handling large file xfers and should not be used like dedicated NAS.Some routers are just not compatible with large size USB drives. If you need a large size drive for files and streaming, a dedicated NAS device would be suggested and prefered over USB drives.

T440 + USB 3.0 Dock = Loses network connection

Our company is in the process of upgrading all our Windows 7 clients (x200) to Windows 8.1, but have run into a strange issue on our new Lenovo ThinkPad T440 PC's. They seem to lose network connection shortly now and then.
This results in several issues like:
- Office 2013 programs crash when working witt documents on the network. (Outlook 2013 crashes if using .pst archive files on network shares.)
- Printers are displayed as unavailable. (Need to restart Print spooler, before it realises that the connection has been reestablished)
We are using ThinkPad 3.0 USB docks, if these might be the cuase?
The eventviewer is pretty silent in most cases when users experience the connection loss, but can the following 3 messages tell anything?
- The speed of processor 3 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 71 seconds since the last report.
- The user account is in a different forest than the computer account. The processing of Group Policy from another forest is not allowed. Group Policy will be processed using Loopback Replace mode. The scope of the user policy settings will be determined by the location of the computer object in Active Directory. The settings will be acquired from the User Configuration of these policies.

You guys have any ideas what I might try?

Working for DisplayLink, I would recommend v7.2, as it fixes a number of end user issues that were coming up on previous 7.x versions.
The lid can be closed, but usually the laptop will be configured to go to sleep when the lid is closed. This can be changed in the Windows settings. We have an article on how to do this here.
V7.2 includes a completely new Ethernet driver, which was designed to try and improve speed and reliability. After upgrade it might be worth removing all cables from the dock, power cycling it and replugging, just to make sure it is updated correctly.
We know of an issue that can cause a slow upload speed with some host controllers (ironically we turned on a change to try and improve Ethernet speed, but seems to have problems when used with some PC host controllers) and I wonder if this is the issue you are seeing.
We have a fix for this in our next 7.2 maintenance release which will be available in the next month or so.

LaserJet Pro 200 color MFP m276nw no network connection with Linksys HUB

Hello
I've setup my LaserJet Pro 200 color MFP m276nw to connect to my home network using a wired connction.
When connected directly to my router the connection initializes and successfully recieves an ip address. I've been able to access all the network function connected to my router directly either wired or wirelessly.
I also have an old Linksys hub and when the printer is connected to the hub, it does not initialize the network connection. The hub works with every other sevice in my network, including a few game consoles and a Mac Mini.
Is there an advance network setting I should be looking at?
Thank you
This question was solved.

Hi,
Remove any wired connection before attempting to connect via wireless.
Print off the printers network configuration and check the settings against your routers settings.
Ensure that router and printer are using the same frequency.
Review this HP posted information once you have the above information in hand.

HP Color LaserJet CP2025dn Printer Wired Connectivity and have USB simultaneously?

Hello to all;
Thank you in advance.
I have a HP Color LaserJet CP2025dn Printer.
The question, can I use ethernet connection and have USB simultaneously? Ethernet is faster, right?
Currently, I have the printer connected to network via Ethernet Wired Connectivity through an Apple Aiirport Extreme base station. I have several Mac's all operating under 10.9.1, and two PC's (one is WIN XP, and the other WIN 8.1), which all operate fine with 2008 wired/wireless technology. I know what a dinosour. I am in the process of upgrading the household to current wireless technology with a NetGear AC1900 Nighthawk Smart WiFi Router (Model: R7000), 802.11ac Dual Band Gigabit, with two USB ports ((1) 2.0 and (1) 3.0) . I connected the printer directly into the Netgrar router, and it wouldn't print, ran setup through the Mac and Win computers and still wouldnt pring. One of the reasons that sold me on the Netgear router was the ReadySHARE® USB access—Wirelessly access & share. In order for me to utilize the ReadySHARE® feature is to connect via a USB cable. Sob story, the longest USB cable off the shelf usually 16", and to reach where the printer is now, I need @25-28 feet of cable. Is ther a maximum length of USB that I can use with out suffering loss of speed/functionality?
Again thank you for your time

I am sorry, but to get your issue more exposure I would suggest posting it in the commercial forums since this is a commercial printer. You can do this at http://h30499.www3.hp.com/hpeb/

HP Officejet Pro 8600 Premium printer LOSES NETWORK connection daily

I've had my printer for a few years. I've had no problems with it. Suddenly in the last week it refuses to maintain it's network connection. It is WIRED. It has a STATIC IP. The router is set up to reserve this address for the printer.
I have uninstalled ALL HP software, downloaded the current versions and reinstalled. It works fine. If nothing is printed for a period of time (not sure the interval) it refuses to find the printer.
Powering off the printer will reset it to work fine.
I've checked EVERYTHING.
There is one article about this happening on Windows XP and talks about changing the ink alert but I've tried following those instructions and I canNOT find anything it is talking about.
I verified that printer is using current firmware.
When it loses it's connection to the network the router can't see it either.
HELP. It is most annoying to have people yelling at me all day to fix the printer.
NOTHING has changed on my printer set up.
The only changes to my network recently were installing 3 IP cameras and adding port forwarding for ports 2604, 2605 and 2606. If that were causing an issue I'd expect it to NOT print at all. After reboot it prints fine until it goes a period of time without printing theni t disappears from the network again.

Hello smsdavis, and welcome to the HP Forums.
I see you are running into connectivity issues. I would like to try and help.
I would recommend powering down the computer and printer. Once they are both off, remove the power cord from the wireless router for 60 seconds, and plug it back in. After the router begins broadcasting, power on the printer and the computer.
I would also suggest utilizing this document on Wireless printing center Troubleshooting Issues.
Good luck and please let me know the results of your troubleshooting steps. Thank you for posting on the HP Forums.

Server 2012 R2 Hyper-V Host Loses Network Connectivity

Here's the scenario...
We have two 2012 R2 Hyper-V hosts (VM1 and VM2) in a cluster that have 8 virtual machines that live on them. The servers are each utilizing three network connections that are teamed (Switch Independent, Address Hash). They all go to the same switch.
Three nights ago at approximately 11:30 PM VM2 lost network connectivity. The server was up it was just inaccessible from the network. I could not ping in or out from it, no internet connection, yet the network connection icon did not show that it was
disconnected.
Two nights ago we had no issues.
Last night, same thing happened at 11:30 PM. VM2 loses it network connection.
The only thing that seems to fix the issue is a reboot. Once the server comes back up everything is back to normal.
Anyone have any idea what is happening here? I do not see anything that sticks out in the logs that could point me in the right direction....

Hi Sir,
Based on my experience , first you may need to keep the physical NIC driver up-to-date .
Also please check if there is "VMQ"/"virtual machine queue" property in advanced properties of physical NICs:
If yes please disable it for each team member then check the result .
Best Regards,
Elton Ji

IPhone 6 64g on AT&T loses network connection

My iphone seems to have trouble reconnecting to the att network after being in a place with bad reception, ie metro tunnel or grocery store. to regain network connection I either have to turn airplane mode on and off or restart the phone. anyone else have this problem?

I have the same issue with my Iphone 5 on ATT. It is a hardware issue with the Iphone 5 antenna. I took my wife's Iphone 5 and my Iphone 5, both on the same IOS version, and ran the exact same apps at the exact same time and mine took a big dump while hers kept running perfectly. Solution....1. Narrow down how to make it take a dump. For mine, I run a station on IHeartRadio, check Facebook, check my email, load a lengthy webpage, and send a Imessage in the middle of the page loading. My phone will drop connection EVERY time. 2. Make an appointment at apple. 3. Tell em the issue and let them goof around with it. 4. Every time they say they fixed it, stand right there and force it to lose data connection. 5. Eventually they will run out of cheap fixes and give you a new phone. 6. STAND THERE AND ATTEMPT TO FORCE IT TO LOSE CONNECTION. Do not leave yet!!!! Repeat steps 4 to 6 until you get a phone that does not lose connection. A friend of mine went through 8 phones before getting one that did not lose connection. I am making my appointment now, finally got tired of it crapping out 10 or more times a day.

Lose Network Connection w/AEBS 802.11n when transferring large data amounts

Hi,
I have a LaCie 500GB external hard drive that is connected to my AEBS 802.11n via a USB hub. Lately, when I am backing up my MacBook Pro to that drive, transferring 5GB or so of data, I notice that my MacBook Pro loses connection with the AEBS (i.e. the network goes down) right smack in the middle of the data transfer. I either have to reboot the MacBook Pro -- or -- unplug and replug the AEBS to reestablish connection.
I was just wondering if this sort of network connectivity loss is being experienced by other people doing large data transfers over the AEBS to an external drive?
Thanks.

I hate to be the one adding a "me too" post, but, me too!
When I try to open iPhoto (library stored on a USB drive attached to AEBSn) the AEBSn crashes, flashes orange once or twice and then restarts. Currently running firmware 7.2 because 7.2.1 wasn't allowing me to reconnect to AirDisks after MacBook went to sleep. If the drive is connected directly to my MacBook there is no problem.
If anyone, anywhere has any idea, I'd be very grateful!

Hyper V virtual machine randomly loses network connectivity

I have an extremely odd issue happening on one of my Hyper-V virtual machines. For no apparent reason and completely sporadically my virtual machine will lose all network connectivity. It is a linux Vyatta firewall image. Digging through
the logs shows nothing at all when the machine actually goes offline, but when the machine starts back up I just get a Warning stating the network driver on my virtual machine loaded but has a different version from the server. Server Version 3.2 Client
version 0.2
I've ran the integrated services setup disk and nothing has fixed this. When the VM loses connectivity it is for no apparent reason, sometimes at 1am sometimes at noon, just happens. The only solution is to reboot the VM to bring it back online.
Has anyone else seen this or know of a fix for it? Its starting to slowly drive me insane!
Hyper V Server - Windows Server 2008 R2 - Hyper V Manager Version 6.1.7601.17514
VM - Linux Vyatta Core 6.3

I tried downloading new integrated services disk setup for linux, but Vyatta wouldn't work with it so I was kind of stuck there. And not sure where you are talking about changing NIC to legacy at. I did disable some TCP chimpney settings as
per an article I found, but not sure if it will fix it or not. Sometimes the machine will stay on for a month before losing network connection and sometimes it comes in spurts and happens like 3-4 times over a couple days. Its really odd

FP1600 loses network connection after a few hours

My FP1600 loses its network connection after a few hours. It is part number 185690C-01, with firmware 4.11. I am running FieldPoint Explorer version 3.0.1 and LabView 6.1 from Windows XP Professional. I set it up, and everything runs fine for 4 hours or more. I do not have the network watchdog enabled, and the FP1600 is in constant communication with the host computer in any case. Sometime in the middle of the night the communication is lost. The FP1600 link light
is on, and it is still receiving packets, but it will not respond to a ping or any other communications. Only a power cycle brings it back. The FP1600 is sitting right next to the host computer, both attached to the same network switch. There is no interruptio
n of network services to the two.

Hi Heinz,
We are also trying to troubleshoot this same problem (Intermitten network connection loss with FP1600 Ethernet Module - Error code "33163", Error Message - "FP1600 Connection to module has been lost."). We have checked other possible causes for this sort of behaviour. Including independent assessment of netowork availability at the time of error reporting, connecting dedicated power supply to the FP1600 module, temperature of cabinet housing the module (which is between 10 and 50 deg C), disconnecting sensors connected to various I/O modules connected to this module, increasing duration of parameter "time out" (the time module will wait before reporting an error if it can not access network). However, none of the above resolved the intermittent and random network loss errors.
The MAX version is 3.0.2, and the firmware on the module is 4.17, Labview version is 7.0 and the Operating System is windows NT.
I was wondering is there any information about this problem from any user or NI recently. The only solution looking in to this discussion forum seems to be replacing the module.
