Card lan B51 30 (new)

Hello

I just bought 30 B51, and I have a problem with a LAN adapter.

It keeps disconnecting, as if it's losing the phisycal connection - he works for several minutes, dies for cuople seconds and repeats itself...

She stops literally - the lights go out (on my router also), icon changes to wirelles non-connected (I wireless ruter one too), and of course, the link is dead for cuople seconds.

Any help anyone?

I don't work in IT, but I do not play with computers for over 20 years so, I checked material tried first - three different cables on different ports on the router, with new and old computer, and everything worked well on the old...
However, I found a solution (I don't know if it would be allright to post a link to another forum, so here's the copy/paste of what solved my problem):

open network and sharing Center, click on manage card settings, click with the right button on Realtek PCIe GBE Family Controller (Local network connection) and select Properties. Click on set up, switch to the Advanced tab and change the following properties:

Auto Disable Gigabit > Connect battery or AC
Green Ethernet > disable
Energy Efficient Ethernet > disable

    Please help me!

    If Windows 7 has not recognized the LAN and WLan card, you have not installed the proper drivers.

  • How to open my card reader to insert the card multimedia on my new laptop inspiron 17r

    I have a small door on the front of my laptop (Inspiron 17r). I feel stupid, but how to open to insert my camera media card?

    If this is the same as that on my new Dell Vostro and it looks like a slot in plastic, you just press the plastic slot and release. A dummy plastic card can then be eliminated completely to allow you to put real in memory card.

    This is not the best design in the world - its won't be long before I lose the fake plastic card.

  • How to change the graphics card on the 15 new

    Hello world

    I just got my new alienware 15 and I can't seem to use the nvidia card instead of intel because "fn + f7" no longer exists in this system and some options are provided in the bios.

    Does anyone know how to go the nvidia card in the new system of 15?

    Make sure you have the latest nVidia and Intel drivers installed.  I noticed the same problem on my 15 when I've seen, but resolved as soon as I updated.  I suggest that you install Intel drivers first, and then the nVidia drivers.  So if really don't know the issues, but that's what I did and it works like a charm.

  • e9280t cannot start with the USB 3.0 card (tried several providers) new version of BIOS e9280t necessary

    Hello...

    I bought a new e9280t year last on the HP site complete with 9 GB of memory (now 16), Blu-ray/DVD writer & reader, tuner TV digital Hauppauge, ATI Radeon 4850 video card bi-ecrans, etc... Since then, I've added more memory and a Firewire 400/800 3 card. His running Win 7 Pro (sp1) and the BIOS is v5.29.

    I bought an external drive to USB 3.0 WD (3 TB) and a StarTech USB 3.0 card (Amazon.com). After installing a USB 3.0 card, the system would be powered on for a second then die and then do it again a few seconds later and the cycle continues until the power cord was pulled. Then, I pulled the USB 2.0 card and tried again only to have the same results. The only cards that remained in the system during the trial was the ATI card and the TV Hauppuage card.

    Thinking that the problem was with the USB 3.0 card, I bought another provider (Rocketfish of BestBuy) and installed. The same problem as with the other card USB 3.0, the system does not start.

    No software driver or other changes have been made to the system before installation tent (according to the vendor's installation instructions).

    Given that all failures occur during the power first sequence and cards have been tried with and without power tied to them, that the problem cannot be fixed with an upgrade of the BIOS for the motherboard of TRUCKEE. I could be wrong, but I'm going on 30 years of experience of material as my framework for this review.

    If anyone else has this same problem, it would be good to rally them around and see if HP notice us.

    Thank you

  • Need help to see if the graphics card is compatible / finding new food please

    Hi, I use currently a HP ENVY Office 700-214 I bought a few months ago and recently decided to update the graphics card so I can continue to play with the higher settings.

    I found a 'Nvidia geforce 760' graphics card which I think should be an upgrade of what I use now, but alas, I have to improve my diet in order to use it because it requires a minimum of 500W. So I was wondering if someone could help me with a few questions.

    1: the Nvidia geforce 760 map is compatible with my computer?

    2: could I possibly get links to a few feeds compatible with my computer? (If posible may 1 with a bit more 'W', then I need minimum.) So if I update in the future more I'm already covered?

    Thanks for the help, I appreciate it

    Hello

    Boot in the BIOS (F10) and verify the information in system information. What is the level of BIOS version? If your PC is using version 8 or 80 and above all the NVIDIA 760 should work unless the version of the video in the video card bios expects something different.  In this case, check with the manufacturer of the video card for repair.

    The CX600 Corsair or CX600M will give you enough power head room.

  • Cannot set my Intel 4965agn card to connect to new N Router

    X61T

    Vista Business 32-bit

    With the help of Windows for

    All,

    I have been using G wireless since the purchase of my X61t in August 2008. Finally stepped up to N in my house. (LinkSys WRT310N) MacBook woman has seen and connected without the need to change anything. X61T, however, says he sees the router, but that "the settings saved on this computer for the network do not match the edge of the network. (Mac 1, Windows 0)

    When I roll over the name of the SSID it correctly pointed out that this is an 802.11n signal.

    I looked at the properties of the card wireless in Device Manager and it lists 802.11n Mode as 'active '. The channel width is 'Auto '. I tried the router with 20 and 40... now set at 40. There is a parameter which is confusing to see: the last item is labeled "Wireless Mode" and allows 6 settings with various arrangements of the interface possible wireless standards: 802. 11A, 802. 11 b, etc., all the way to 802.11a/b/g' - but no mention of N in this section. I don't see any other setting that I recognize as related to the connection. Do a search here on this Board and acroos the forums all came with a few bugs I've tried: go into the BIOS and disable wireless then enable, for example.

    Diagnostic tool from Intel PROSet / Wireless works fine until it gets to the Association Test and does not say, "not linked".

    Although the router is set to broadcast a windows diagnosis indicates that the network is hidden. Weird.

    Because the other computer is fortunately I agree with windows that the problem lies in the configuration of the Intel card. 61 x sees the internet via a cable - no problem!

    Thanks in advance for your suggestions!

    Suriya, thank you! You are a consistent help to people here on the forum.

    I have "fixed" the connection - but who put in quotes because I don't know what I did to make it work. I think that these were settings of the router automatically changed by a firmware update I did as part of troubleshooting. Perhaps those (or more exactly do not keep Super-une attention on the order of the changes and related measures) assigned to my sense of what "worked".

    I was about to update this driver to a version of June 2010. I bet that's the link you provided... I found that... but I let the drive where it is until everything else works computer here. Not broken don't fix it...

    Sheesh. These devices of productivity, right?

    Now, I hope that the flavor of "N" is really faster.

    Once again, thank you.

  • Satellite A110 - switch WiFi does not work with the new WiFi card

    Hello everyone

    I have a problem with my laptop Toshiba Satellite A110 - 178 (PSAB0E). I replaced the original Intel 3945abg with Intel Link 5100 WIFI card and on the new wifi hardware wifi card switch does not work.

    New wifi card is discovered and drivers to the correct job but when I try to search with the Intel Pro/Wireless software wifi networks I message to turn on hardware switch, but there light and not work. The old wifi card swich works OK - orange light is on. On the new map light is off and swich does not work.

    Help, please

    Hello

    Do you have also enabled the WLAN functionality by pressing FN + F8?
    Check it!

    In addition, I think the case is clear: the new wireless LAN card isn't compatible with Satellite A110.
    So in my opinion, you must use remove the new card Intel and install the old card that works fine in your laptop.

    Hi, I am looking to update my HD graphics card and buy a new HD screen, I hope you guys can help (I am based in the United Kingdom)

    I see (after doing some research on this forum) that operating systems seem to be important as well anything else.

    If my installation is:

    -OS X 10.8.5 (must keep this for stability problems)

    -Current is card ATI Radeon HD 2600 XT 256 MB

    -Mac model is 3.1

    You are not sure if we need more information on this stuff?

    I currently run a Sony BRAVIA and have other devices connected to it - Blu - Ray, Xbox.  It would be great to get a new monitor too and have enough connection to have all this always running as well as the mac.  I don't know if it's possible, because I don't know how the graphics cards these days above to connect to monitors.

    Help on that would be great.  I was able to get this old beast to keep improving in terms of storage and performance.  It is the missing piece of the puzzle for me.
