Hardware specifications:

http://support.HP.com/us-en/document/c01485372

OS and information network:

  • Wireless router: ASUS RT-N56U on the latest firmware 3.0.0.4.360
  • OS: Windows 7 Professional 64-bit SP1
  • Windows Firewall is disabled

Network card:

  • 6 wireless mode. 802.11a/b/g

Steps in trying to solve this problem:

  1. The option "allow the computer to turn off this device to save power" is also disabled.
  2. I have the power options set to High Performance.
  3. I installed inSSIDer and I'm the only broadcast network on the 5 GHz bandwitdth (so there is absolutely no interference whatsoever)
  4. I spent between the 2.4 GHz and 5 GHz and the same thing happens. See below

Question:

My laptop to find < 50 meters from my wireless router (no walls between the two) and I connected on 5 GHz bandwidth. I get random disconnects all along the day make a red X on the network icon in my taskbar. The only way to correct 'temporary', it's completely restart my computer.

On the other hand, my mother's laptop is in the other room, also connected to the 5 GHz range, ran into problems of ZERO at all.

What could be the problem?

If anyone else knows this problem, are the only two (solutions)

  • "Allow the computer to turn off this device to save power" option checked

OR (if this does not work)

  • 802.11n mode Disable

802.11n mode for Intel Wireless WiFi Link 4965AGN for operating system Windows 7 and 8 is buggy. Which causes intermittent wireless disconnection.

  • Satellite P100-429: Intel Wireless Wifi Link 4965agn card is not compatible?

    Hey guys

    I have a Satellite P100-429 with a 3965abg to intel, I have a few router purchased months ago Netgear wnr834b n project, then think, it is high time, I upgraded my internal adapter.

    I wanted to know if the Intel Wireless WiFi Link 4965AGN adapter would fit that is a right with the 3965 swap, as it says it's connection is Mini PCIe card * and I have no idea if it would fit?

    Hello

    Yes, she should go, because the W-LAN-mini-card slot is a PCI-Express, so you'll just have to swap the cards. But be careful with the antenna connections, if you bend them too so they break very quickly and then there is NO WAY back and you will pay for the exchange of
    the whole cover, where are the antennas of screen.

    Best is to contact a local service partner if they exchanged, you don t therefore the risk for the guarantee void if you do something 'not very good' on your machine. :)

  • Intel Wireless WiFi Link 4965AGN with Inspiron 1525 problems

    I have Inspiron 1525 + 8.1 Windows + Intel Wireless WiFi Link 4965AGN (Intel last driver for Windows 8). If I set the off mode N card wifi, wifi is more slow (54 Mbit/s), but stable. If I turn N (enable) mode, wifi is fast 144 Mbps, but becomes unstable - often (few minutes) disconnects, the disconnection of the card shows a lack of drivers, you cannot reconnect to the router, you must restart your computer. Another computer - Dell Studio with pre-installed map 5100 is stable under the N on my home network. Dell officially submitted the 4965AGN card is compatible for Inspiron 1525. Is it possible for stable operation in N mode?

  • Dell Latitude D830 and Intel® Wireless WiFi Link 4965AGN drops connection

    Hi all

    I hope someone can help me here. My laptop keeps giving up the connection to a modem within 20 seconds after the connection. I run XP Professional, my ISP is sky and I have a Netgear modem provided by Sky.

    I have another machine running Vista (an Acer Aspire 5670) here and I'm having no problem with stay connected on this computer.

    I am able to stay connected on any wireless network, except on my own modem. (I recently traveled and was able to connect in hotels, airports and conference centre without losing the connection once!)

    I recently moved and the problem existed at the old House and now in the new House too. Initially we thought it would be more aggressive radio trying to get a signal strong (er), abandoning the connection looking for another, but it only happens with this modem. There are approximately 11 other networks in range. I changed the radio signal to all channels, nothing did.

    Sky said it is not the modem and they can't send a new one because clearly there is no problem that the other laptop is connected correctly. I am at my wits end here because I couldn't stay connected wireless to the House since I have this laptop (almost 3 months now) HELP!

    PS, Connection to the LAN is no problem through the same modem, it's just the wireless connection connects and then abandoned.

    The Intel wireless event viewer shows:

    authentication, and then said: 'itinerant event of pilot '. Shortly after Unauthenticated (name SSID)

    Authentication is ok for these 20 seconds, I'm connected, I'm able to access e-mail and the internet

    Hello

    Check if the wireless network adapter using the Draft N standard.
    You can choose this in Device Manager-> properties-> Advanced tab WLan card

    As far as I know that the WLan card is Intel 5100AGN.
    Check if an update of the WLan driver would also help

  • Problem with update of Intel for Intel (R) Wifi Link 5100 AGN driver

    Hello

    I have Windows Vista, Office 2007, and when I download the update recommended above makes my Internet become very reliable. Some Web pages is not affected, but some will not work. There is no obvious reason why this is the case for all advice would be greatly appreciated.

    Thank you very much

    Paul

    Hello

    You tell us where you found the recommended update.

    ________________________________________________________

    FYI for Windows updates:

    Microsoft gives sometimes you updates for the 3rd party hardware: graphics, network cards, etc.

    You should only get the latest drivers for them to real hardware manufacturer's website, as Microsoft normally does nor those have the most recent drivers available as Microsoft relies of the 3rd party hardware Manufactuer to provide.

    But unfortunately, the only way to know which is the update of the problem is to install them one by one, until you find the 'wrong' for your installation.

    You can do a system restore to get back until it has been installed (which is NOT the best way to remove an update) or follow this method:

    'Remove an update'

    http://Windows.Microsoft.com/en-us/Windows-Vista/remove-an-update

    When you have found the issue of update of the list of updates which is presented > then right click on the update problem > select Hide update > and it will not be available to you once again

    "How to hide or show an update of Windows Vista"

    http://www.Vistax64.com/tutorials/72491-Windows-Update.html

     

    Here's how to chanage update settings, if you think it is necessary to:

    "Understanding Windows Update and Extras in Windows Vista and Windows 7.

    http://www.bleepingcomputer.com/tutorials/Windows-Vista-updates-and-extras/

    Or the other of these two update settings will give you the chance to see what you want to install through Windows updates;

    Download updates but let me choose whether to install them - if you select this option, Windows will download the updates on your computer, but not install them automatically. If you want to install updates, then you must install them manually. You should only select this option if you have a reason to not install updates automatically. Only advanced users should use this option.

    Check for updates but let me choose whether to download and install them - if you select this option, you'll be alerted when there are new updates available for download and install. You can then choose to download and install the updates that you want. This option should really be reserved for people who know exactly which updates they need, or those who have little access to the Internet.

    But remember you normally only have problems with hardware 3rd party drivers. Other updates are to improve the Performance and security of your system

  • problem of Intel(r) Wifi Link 5100 AGN WiFi modem

    I have the modem title in my laptop that I inherited from my sister. I got home and it does not connect. I ran a diagnostic and it says that there is a problem with the driver. I did the update and represented the diagnosis. Same thing is happening. I went to Device Manager and not the diagnosis, and he says: I use the highest driver so far and that the modem is working properly.

    Help! A diagnosis says it does not work, it says it does. What should I do here? Any help would be appreciated!

  • Can I use Intel Wireless Display - Netgear PTV1000 on Satellite U400-157

    I want to use the NETGEAR PTV 1000 wireless display device. The hammer on the Net says I should be able to use it if I change the operating system to Windows 7. I see that I need http://www.intel.com/support/wireless/wtech/iwd/sb/CS-031059.htm Intel Wireless Display to use.

    The Intel Wireless WifI Link 5100 wireless on the Satellite U400-157 is. Seems that it is not one that is required to run the PTV 1000? So an operating system for Win 7 can not allow me to use the PTV 1000?

  • System/Intel WIFi Link Wireless problems

    I have a HDX18t, running Vista.

    I have two things on course, that can be linked to another.

    First of all is a problem with the wireless assistant. The wireless on the keyboard area light is always red/orange. It will not change to blue when you press. Wireless Assistant does NOT open when I tell him. Now, I had this problem in the past and was able to remedy somehow after research on the internet. After much searching this time, I can't understand what I did or where I found the solution.

    Now, here's the other thing that happens.  When I run the Diagnostics Windows network, one of the messages is "NIC"Intel(r) WiFi Link 5100 AGN"experiencing driver or hardware related issues.»  It is a new motherboard, which I really hope has nothing to do with it.  I hope that the Wireless Assistant holds the key...

    It won't let me connect to internet to even try to fix or something.  I know that everything is fine with my wireless network, because I have another laptop which works very well with the wireless netowork.

    Well, we discovered that 'someone' has put the WLAN module in the spot of TV tuner! We changed it and now the blue light comes on, and we are able to get online! Thanks a lot for your help! I'm sorry, we didn't know about this before, but you said that it must be related material! You were right!

    Problem solved. Of wire antennas was not of all attached to the card and the other it has established relationships by chance. It took me 3/4 of an hour to turn off the battery, remove the keyboard, attach wires to the NIC (quite difficult due to lack of space) and put it all together. Then everything worked fine.

  • HP Pavilion 9500: Supported wireless card doesn't work is not in Windows 10

    I just bought a new card WiFi Intel Centrino Ultimate-N 6300 to my PC HP Pavilion 9500/entertainment because the original a (WiFi Link 4965AGN) is no longer supported on Windows 10. I have the Driver IRQL NOT LESS or EQUAL (Netwlv.64.sys) BSOD a few times a day.  According to Intel, the Ultimate_N 6500 is a supported card, but once I installed it, it will fail to start; He told me that my network card is not taken in charge and remove it please.

    Here, any help would be greatly appreciated!

    Thank you!!

    Then, you will need to return the o/s supported to ensure that the equipment works as I have said, you use what works for her, not what you want. What you want and what works are the two different side of the same coin.

    I guess the easy option would be the easiest route to take. I wasn't going for simple, I expected a little more creative way to solve this problem; workaround to allow W10 supports my original legacy wireless card or a way to remove the restrictions on the white list by HP to enable my new card.   It seems that this is not the right forum for this.

    No there's a white list of BIOS that will prevent the installation of any wireless card other than that provided by HP with the original from the sale of the unit. And there must be a version of HP of the card, not only the same chipset. Pages 57-58 lists the options available:

  • Intel WiFi Link 5100 network card - cannot detect wireless networks

    I have a HP Pavilion dv7-1270us. My wireless card is an Intel WiFi Link 5100.

    Running Windows Vista 64 bit, Ubuntu Linux, Linux Mint and Fedora Linux (various versions, all), the wireless works fine. My desktop computers to work with wireless cards to connect to the network work very well, and all computers (except mine) to connect to my home network very well; which means that it is not a problem with wireless networks, or with my network card. I try to manually connect to the network, but it can't find it. Diagnosis requires that the card is disabled, and that I should turn it on via the switch on my laptop running: fact.

    During the installation of Windows 7 64 bit, I cannot see wireless networks (and therefore unable to connect). Re-formated and reinstalled again, check the wireless connectivity between each batch of Windows Update, but it has never worked.

    I downloaded the latest drivers from Intel, via Microsoft Compatibility Center (version 15.2.0 driver).

    There is no system restore option because he has never worked as a first step, except in all other OS, I got on the computer. Microsoft Compatibility says the map is compatible, then Device Manager shows no problems. The network adapter is active via switch on my laptop.

    Happy that you guessed it sorted!
