OfficeJet 8600 loses its Wi - Fi connection while trying to analyze

I have an Officejet Pro (top-of-the-line) 8600 and I use this for my real estate business.  This means that I constantly analyse documents.  I bought this printer about a month ago, and I have multiple issues with the printer 'drop offline.

The time I noticed it most is when I will execute a function "Scan to Computer" or even "Scan to Network Folder.  When this happens and I am scanning documents, sometimes it's going to happen the first document and sometimes it won't get through 2-3 documents before the BLUE wireless light disappear and then start flashing (which means that it is again acquired a wireless signal).  Therefore, I lose my fax, and I have to try it once again.  My backup plan is to scan to a USB key, but not ideal at all (I bought this printer only for wireless capabilities).

I notice from time to time when I'm on the computer, the icon "Scan of the computer is no longer active" momentarily (which means that the printer was offline for a few seconds).

I made a page of configuration/network test and the signal was strong (5 of 5) and there is no problems through the test.  However, whenever I try a scan, very rarely the scan be completed and go to my computer.  What can I do?  I'll have to check, but I think I'm deconflicted regarding IP addresses (but if there is a de-escalation, wouldn't it not allow me to connect on the wireless at all?).

Has anyone else had problems with the features the Officejet 8600 series wireless?

For the off topic answer the first question, Netgear and 2Wire, which AT & T uses normally, should be substantially the same as, that shouldn't matter.  In addition, two router radio wireless networks that together could interfere with each other.  If you have a router that AT & T has failed, you need to get a standard modem from AT & T to replace the router modem combination to avoid that from happening.

Now on the problem of the accutall at hand.  I see two things from the information that you gave me and which could contribute to the problem.

The first is your encryption type.  WEP is actually the type of secure encryption leaste you can use, and can cause problems in connection with the printer.  HP printers work well with the type of WPA - AES encryption.  WPA - AES is also the most secure encryption type, that you can use right now.  If you are not comfortable change, contact AT & T and they should be able to help.

The second thing is the AVG software.  He doesn't like most of intra-network communications.  I don't know why since everything is behind the same firewall router, but don't like AVG for two devices on the same network communicate with each other constantly.  Fortunately you can tell him to stop obstructing communication by opening ports in the firewall to allow scanning through.  I will list the ports at the end of this post.

Try these things and let me know what happens.

    Such a potential doe to a communication problem.

    Try to connect the USB directly to your PC and not via the docking station, restart the PC and follow if you see similar behavior or not.

    If it doesn't happen when you're connected directly I recommend you to check if there might be an update of the firmware available for the docking station, if happen you I suggest trying another USB cable and check for the difference.

  • OfficeJet 8600 (firmware CLP1CN1232AR) cannot connect to WiFi after firmware update

    My printer recently auto-mis updated my HP Officejet 8600 it is firmware CLP1CN1232AR and after that, it is no longer able to connect to my router. I can connect to my old router R6300 with her, but not my new WNDR4700. Newspapers say he is rejected for wrong security. I can connect to the R6300 and then give him the exact specifications (WPA2 AES), but it still does not connect. I don't know why the WNDR4700 is no longer, but something has changed in the last firmware that make it miserable. Is it possible to downgrade the firmware? There is another difficulty to operate? Other people have trouble with the new firmware?

    Posted my problem on another forum, thinking the new laptop caused the problem

    Resolution is the same: restart the router!  So simple, but who wants to go up the road to the ' net?

    Router is a cisco Linksys e1000.  Apparently an HP upgrade was nestled among these 25 MS Windows downloaded when I got on the road.

    Thank you and Bravo!

    This may be caused if you have configured the computer to use the same static IP address.  To see if this is the problem, follow these steps:

    With your computer connected correctly, follow these steps:

    Open a command prompt window (type cmd in the search box and press enter)

    In the black command prompt window, type the following command, and press ENTER after each line

    ipconfig/all > "% userprofile%\Desktop\ipinfoONE.txt".

  • External USB hard drives lose its connection and work stoppages. __

    External USB hard drives lose its connection and work stoppages.      History
     
    Windows 7 Ultimate - 64-bit
    I installed it on a HP Pavilion, OS, 64-bit, and I have this problem.
    People report that it does not occur with Windows 7 32 bit OS.

    Problem:
    Any brand of external hard drive USB (and other USB devices sometimes) lose its connection and stops working only when copying large files internal drive to external USB drives.
    The USB device may appear to work properly when Windows first starts, but later stops working (crashes computer) after the start of large files to copy. You must restart Windows for the USB is working again.
    This only occurs when you copy files large files to THE USB port, not on the internal drive. It happened when I synicing my IPhone with Itunes when it started the synchronization of music files.

    According to the suggestions I have:
    1) updated the BIOS from the websites of the manufacturers.
    (2) power management disabled on the USB hub for disks
    (3) ensure that the BIOS for Legacy USB is set to.  I don't have this option in the BIOS settings.
    (4) this is not a motherboard problem, it is located on three different MB that we use.
    Also tried three different USB drives and different cables.

    Because I tested with two different computers updated and USB drives, our opinion is that this problem indicates that the Windows 7 64-bit operating system.

    Someone knows a solution?

    Hi Jh6284,

  • Continuous wireless network adapter lose its network connection

    It used to work very well in the beginning, but after a many windows updates, my laptop has started to lose the Wi - Fi connection every several minutes.

    ... I suggest you to update BIOS, chipset and wireless network drivers these links and check if it helps...

    Hi, Yann,

    I updated the driver, but it did not help. Update the chipset has probably not because I have AMD (the update says that I don't have the required devices). BIOS has been updated some time (I have the latest).

    I also searched other topics and did the following:

    Disabled IP assistance service;

    Value another configurtion IP: manual and entered a fixed IP address and the default gateway.

    Turned off the Windows Firewall for this network.

    The problem seems went, at least for now, although I don't know what stage did.

  • HP Officejet 8600 more print and scan problems

    Hello

    I had my HP officejet 8600 more for 2-3 years and always had problems following and just kept reinstalling the drivers as a quick fix. I am now starting a business from home and I have no time to deal with printing and scanning the questions and, of course, my warranty has expired! My operating system is OS X version 10.9.4.

    When I scan to my computer, the printer indicates "not found computer." The status of my mac is no different than when I scanned a document a few days ago! Remove and reinstall the drivers solves this problem temporarily but I want it fixed permanently.

    In addition, when printing, sometimes a page can print immediately and at other times, it may take 5-10 minutes to print even if its status is 100% full in the print queue - even once, reinstall the drivers is a quick fix but I want a permanent solution.

    Any help to solve these problems would be greatly appreciated.

    Thank you very much...

  • Copy/scanninf with HP Officejet 8600 pro problems

    I have a desktop HP all-in-one running Windows 7 (64-bit). The printer HP Officejet 8600 pro range is connected to the printer via a USB cable. Scanning/copying is all lines verticle edge edge of the paper. I ran the HP scan doctor software and it showed that everything works. Still no usable copy. Search HP site and the forum of solutions. Tried what I found. Still no solution found.

    Well, I thought was this Chantilly when a blogger told me to try another outlet. It worked for a while. Now, the scanner lamp isn't bright lighting as it did before. She is dark, almost orange. The printer's two month warranty. Is this a bad sanner lamp or something else?

    Can someone help me solve the problem?

    Thanks for the pointers. I'll try them and I hope that this solves the problem.

  • OfficeJet 8600 Pro +-switch lamp cycling light then dim

    My printer Officejet 8600 Pro + is brand new and is connected via my cable network. It works perfectly until now. Wi - Fi and fax are also well (deliberately) turned off / disabled & unnecessary.

    The power switch has a beautiful green light to indicate that the printer has "power" OK - and the lamp seems to have two "on" States, namely 'dim' and 'bright '.

    The printer seems to go into "Sleep Mode" OK, and the control panel goes off as planned after my predefined interval 'Sleep '. (I do not use the schedule options).  She also wakes up OK when I send a print job.  Once again, everything is going well so far...

    While the printer is in this state of 'ECO' of low power, the intensity of the Green switch lamp varies slowly between high heat and Sun, on a cycle of 6 seconds - 3 seconds to "quick", then 3 seconds to "dim" and it keeps road - bright then dim then bright etc...

    BUT... and here's my question... This lamp should stay there "dim" while the printer is in sleep mode?
    Alternatively, the fact that he is back to 'light' all seconds imply that it is somehow failing to STAY fully 'asleep '?

    I can't find clues about this in the manual of the printer.

    Maybe I should raise a query with people to Support HP, but I thought I'd ask here first.

    Thank you in advance.

    Edited to add:
    I would be happy to know that any other Officejet 8600 owner (or the owner of any other model Officejet) sees this same high heat/Sun behavior on their switch lamp?  Thank you.

    This is normal. All 8600 printers here at my place doing the same thing. He is to inform the customer that the printer is in mode 'sleep' and not completely extinguished. I hope that helps answer your questions.
