WiFi driver problem

I have a laptop Y50 in a few days and I noticed that when I install the drivers for the wifi from the cd provided with the computer WiFi works well but with maximum 72 Mbit connection. When I choose windows to search for drivers more recent it installs latest, the connection goes to 150 Mbps, which is the maximum of my router but with limited connectivity and does not work. I chose to roll back the driver, wifi still works well, but back to 72 Mbps. I tried the drivers from the support section Lenovo that the same problem occurs. I tried the drivers of Intel support page but with the same results. Everything works fine with 72 Mbit connection I get with the old drivers, but I'd really like to do repair and use the full potential of your PC.

I managed to figure out what was the problem after all, and he was not with the drivers. I use a router Tp-link model 740N stretching on 2.4 Ghz frequency. When I install the latest drivers for the card wi - fi adapter default setting is set to work on 2.4 5.4 Ghz mode or auto. This setting prevents the laptop to connect successfully with the router. I changed it to prefer the 2.4 Ghz band on which my router transmits and the wi - fi on the laptop got working with the maximum 150 Mbps connection between the laptop and the router. So far, works very well.

  • HP pavilion 1200tx g4 laptop: wifi driver problem

    Hello world

    I can't find the Wifi driver for my system and get some annoying drivers in the Device Manager window.  . Help me and provide me with the details of the correct driver.

    Hello:

    You already have all the drivers except the wireless card, depending on your screenshot.

    The hardware ID you posted confirms that the wireless card is the Broadcom adapter, so I don't know why this driver did not work.

    Try to manually install the driver Broadcom I posted above (sp57965).

    Go to Device Manager and click on the network controller needing drivers.

    Click the driver tab.  Click on set to update driver.  Select her browse my computer for driver software option and navigate to the folder of the driver that was created when you ran the file.

    This file will be located in C:\SWSetup\sp57965.  Make sure that the include subfolders is selected and the driver should install.

    As you can see from this partial copy and paste of the installation of the driver information file, the hardware ID for the wireless card you have in your laptop is supported by this driver.

  • Lenovo S10e WLAN WIFI driver problem solved

    I recently reinstalled XP on a S10e but could not get the WLAN to work. I have installed all the drivers on the site of lenovo for the S series broadcom drivers but without success. Then were

    2 weeks later I then re-formatted and installed Windows Vista but the same questions again.

    Solution

    Go to Device Manager and select the Details tab

    Summer of my number VEN 8086 DeV 4327

    I then went to http://www.pcidatabase.com

    the details entered and found this camera was an Intel (R) WiFi Link 5100 AGN (according to the id of the chip)

    (use the search function of the browser with the device id number-saves a lot of time to go through the list)

    follow the link to http://downloadcenter.intel.com/Default.aspx?lang=eng

    and found the corresponding device id

    Wireless > Intel Centrino WIFI Products > Intel WIFI Link 5300 and Intel WIFI Link 5100

    the driver for my OS installed and now everything works 100%

    It seems that the device in the BIOS id is incorrect or that it really is an Intel chip not broadcom.

    I hope this helps many people who have the same problem that I had and ends the traul endless on getting the WIFI works again.

    Good luck and let me know if it works for you

    Also all the other drivers have been installed automatically with the VISTA install no need for driver downloads (except bluetooth installed under automatic updates - is not I use it anyway)

  • v3-372 wifi driver problems

    Acer driver download page shows 3 wireless lan drivers. I need help to choose who, or are you supposed to install all those? Tought it is relevant because without a special driver that my wifi speed is about 10 MB/s link altouhg speed is 866, 7 Mb/s, I'd be happy with half of the link speed. (I know the difference between bits and bytes and I know that there is overhead) I scanned with speccy and everything it says it is Qualcomm-Atheros outskirts of QCA61x4A wireless adapter.

    Hello

    At the back of the laptop must be a sticker that tells you exactly which module you have. View and download the drivers that are mentioned on the label.

    Also, if for some reason you still have no improvement, try to install another driver who is more recent. Based on the above condition number, I was able to find this:

    This laptop has a wireless white list that blocks the start if the correct card is not installed. You must purchase a wireless HP part number card.

    The laptop is 10 years old. It is the only card in the manual for the United States. Don't know where you are and which may affect the part number you need, but it's the American part:

    802.11a/b/g module LJ WLAN for use in the United States and the Canada. 407254 001

    Here it is on eBay:

    http://www.eBay.com/ITM/Broadcom-Mini-PCI-Express-card-BCM94311MCAG-407254-001-/221004274059?hash=item3374e1998b:m:mLUBTJNR7QLs7JVwODHLsiw

    He must have the SPS number HP part number. I suspect that your card is bad and others that you tried to buy are incompatible, then you will need to get one like the above, if you are USA or the Canada.

  • HP Pavilion DV6 3050TX: (low range) wireless network driver problem

    My hard drive and motherboard both damaged so I installed a new hard drive and the motherboard and install a new copy of Windows 7 Ultimate (64 bit). But after installing a new copy of windows, the serious problem that I found are to find the right drivers for the wifi and bluetooth. HP has listed a lot of driver for bluetooth and WIFI but that is just and appropriate is not found. Not my WIFI range is decreased. Whenever need to uninstall the driver and reconnect after a few hours of use. As his 'Problem with access point or wireless adapter' shows in troubleshooting.

  • HP Pavilion G6 - no WiFi Signal - problem "Broadcom 4313GN.

    Hello

    My laptop (HP Pavilion G6, PN: QG846EAR #ABU) with Windows 7 Home Edition is to have through its WiFi connectivity problems. The WiFi hardware is recognized as "Broadcom 4313GN 1 x 1 adapter Wi - Fi 802.11b/g/n" by the Manager of devices but it cannot detect all autour WiFi signals. I tried deactivating and activating it by FN - F12. This action works, but does not affect the situation. Initially it was the driver version 5.100.82.82 as of the 20.05.2011.

    I found two new updated driver from Broadcom and HP sites, but none worked. (ver: 5.100.82.95 - date: 1.4.09 and worm: 5.100.82.139 - date8.5.2012)

    I restored default Windows 7 Home but this does not work either.

    I started with Fedora and Knoppix live CD but none managed to see any signal, even if the two detected the correct WiFi hardware.

    I have checked and then changed the values in the BIOS by default, but this did not help.

    When a WiFi USB is plugged in, the PC works fine.

    Under the battery, the WiFi device is referred to as "bcm94313hmgb".

    Any idea?

    Say hello to new mscag.

    Thus, one of the sons is not connected?  It's probably the cause of your problem.  Take a look at your notebook PC Maintenance and Service Guide.  Specifically, look at page 54, which deals with the removal of the WLAN card.  He says that there should be two wires to disconnect (main and auxiliary antennas).

    I can't say very much in the picture, but it seems that you should be able to reconnect the loose wire.  I suggest this thread connected and if this does not resolve the issue I would then contact HP support.

    HP to support an appeal to the United States / Canada you can call to the 1-800-474-6836.  If you are in another part of the world, you visit HP's Support around the world to find the coordinates for your region.

    Let me know if plug this cable solves your problem.  Have a great rest of the day!
