Possibility of updating firmware in Deskjet 6840?

I got a HP Deskjet 6840 for a long time and it still works very well.  I was wondering if its possible to update the firmware on the printer for him to use the network of my network security servant (that it does currently not support), which is the WPA2-PSK AES?  (I currently have the interface through a wired connection)

No, sorry, this is not possible.

    After a few minutes the wireless connection is lost.

    I use e-print, or fax function, the same thing happens. Lost wireless connection.

    Not possible to use ePrint settings.

    'Lost' mode it is not possible to print reports, etc.

    If I turn on and turn on the printer it works for a few minutes, then returns to the error state.

    Where can I find more old firmware to reverse and to have a functional printer?

    Thanks for your tip!

    While preparing for the partial resetting, I found under network settings > reset to the standard network settings.

     


    After that I've reconfigured the network and now it seems stable. I see that it stays on if I do the reset.

    Thank you.

  • Update Firmware of BMC R610 of linux

    Hi mates,

    I need to update a few R610 servers, I would like to only update the BMC Firmware if possible without shutting down the machines, is - it possible? I'm running debian on these machines.

    I open it because I've been Googling much this and I found that maybe there are several ways to update the firmwares of server, including the iDRAC completely update, etc., but I am only interested to get the latest patches of cooling, so I guess that should be only update BMC.

    Could you please some direct me in the right direction? I looked and I found some binary files in dell FTP, but I need to be sure of where to find the correct firmwares for my machines and what is the most common method through linux so far.

    Thank you comrades, I appreciate the help.

    Hello

    There is no separate BMC firmware in R610. You need to update firmware iDRAC who BMC features as well. Down, you can load the latest firmware iDRAC at the bottom of the location

    http://www.Dell.com/support/drivers/us/en/04/DriverDetails/product/PowerEdge-R610?driverId=63KCR&osCode=NAA&FILEID=3287900761&LanguageCode=en&CategoryID=es

    You can update the firmware iDRAC without stopping or restarting the system. As you have debian on these machines, I recommend you update iDRAC using Web GUI. You can check below link with a video on the updating of the process. First half of the video is on the download of the image that has changed a bit. You can download the File Format 'Application' link above.

  • Update firmware on Satellite A200-1gh - noise emissions under Linux

    Hello

    I have a serious problem with the sound on Toshiba laptop. Many people have the same problem I have.
    An example:

    ________________________________________
    Hi there everyone
    straight to the point, I got no sound running ' bt3 beta computer laptop - Toshiba satellite a200 - 14 d, HD audio - Realtek ALC862 @ Intel 82801GBM ICH7-M - audio. I tried to fix it with a blender Kmix or alsa, even downloaded the Realtek driver name and installed, but bt3 built in Realtek driver. Still nothing"
    ________________________________________

    My laptop contains this sound card: 00:1 b. 0 Audio device: Intel Corporation 82801 G (ICH7 Family) High Definition Audio Controller (rev 02) @ Realtek ALC861-VD. There is a problem somewhere in the firmware of this map or the Linux kernel.

    We use Backtrack 3 who is Slax based Linux distro.
    I've been with many professional talking about Linux, Bud, no one is really sure what is the problem. They said several things to try; one of them is updated firmware. I've never done this before, I'm looking for help.

    Number of exact model of my laptop is Toshiba a200-1GH psaece

    Please help if you can

    > There is a problem somewhere in the firmware of this map or the Linux kernel
    What are you talking about boyfriend? This firmware of the sound card that you hear?
    I think you're confused.

    First of all there is NO firmware for the sound card. Second, the sound card is controlled by sound driver.
    Always is it that Toshiba laptops are preinstalled with Windows OS.
    Linux is not supported at this time, and you won't find driver for sound card for Linux.

    If you need a sound driver for this sound chip, you will need to download it from Realtek Web site!

    That s all about your firmware to his mysterious map.

  • Satellite A100-207: is it possible to update the graphics card for games

    Hello

    I am looking to buy the laptop Toshiba A100-207 and it comes with 128 MB shared graphics.

    I would like to play games and I was wondering if I could update the graphics (for example, a nvidia card I could buy and put in) or the fixed graphics?

    I just want to know if I am able to upgrade?

    Thank you

    Hello

    In my opinion the graphics card or processor is not welded on the new generation of mobile phones. The parts must be simply plugged into the card.
    But this does not change the status of the upgrade.
    Eventually, you will be able to remove the graphics card but I m sure that you will have problems of compatibility with other hardware.

    Fastest graphics card produces more heat and the temperature will automatically increase to a higher level. This would lead to overheating in the question and the laptop would be either closed or not starts.
    PC desktop technology is simply different as on laptops. You can also compare different graphics cards. Laptop factory uses only graphics card chips what don t supports a clean cooling module.

    It simply says s not possible to update the graphics card.

    My laptop is a series of Satellite Pro A300 PSAG9E and when I try and install a firmware update a box telling me it's not compatible with my system.

    Hello

    No, it s not possible to update the graphics card to another.
    As you certainly know, the laptop technology is not the same as the desktop PC simply. It s the motherboard technology all just different. You know that heat is a bigger problem for every laptop and generally of designer, developer and manufacturing. In addition, the various interfaces are not equal.

    For example: what do you think, why Intel doesn't produce chips with speeds of 10 GHz, 100GHz, or 1000GHz. Because of the heat.

    I think that the graphics card performance will produce more heat, and this could lead to overheating problems.
    The other graphics card needs another module of cooling and the cooling module must be compatible with the motherboard. Everything needs to be changed (the case design, interfaces, etc.) before the upgrade might be possible. In my view it is simply not possible at the moment.
