ProBook 440 G1 continually lose Qualcomm Atheros WLAN connection

Hello world

I just bought the HP ProBook 440 G1 free BACK. I have intalled Windows Pro 8.1 and installed divers downloaded directly from the center of Support of HP in this link. For the wireless drivers, I realized that the I have the QCA9565 of Qualcomm Atheros 802.11b/g/n WiFi Adapter and also Qualcomm-Atheros Bluetooth 4.0 QCA9565 adapter, so I downloaded the latest drivers from here (1.00) and here (11.0.752.0) respectively.

In a few minutes using the laptop, I noticed a steady decline in my internet connection. I checked my router and everything will, work well with other gadgets. So I searched the Internet and found the same problem for other models. However, here and here official HP solutions, apply is not for my Qualcomm-Atheros. I even tried to install the drivers updated in these solutions, but nothing is happening because they are specifically desgned for the Mediatek combo (Ralink).

Finally, you also you know that I've updated the BIOS with the latest version (01.20 REV. (A). can someone help me solve this problem please?

If the research on mine, I found many new versions of the driver that is compatible with my QCA9565 WiFi and Bluetooth component as listed by the official support from HP.

I started with this:

  • [Questions] Official HP 10.0.0.270 (5 December 2013) here
  • [Questions] Official HP 10.0.0.270 (17 February 2014) here

But my problem has not been resolved, so I tried unninstalling those and the installation of these:

  • [Problems less] Bundled WiFi and Bluetooth for AR9485 10.0.0.276 (12 December 2013) here
  • [Much less questions] AR9485 10.0.0.287 (March 25, 2014) here
  • QCA9565 10.0.0.297 (July 22, 2014) here

With the latest driver I have no problem at all, everything works fine. I suggest you download and install the bundle complete 276 (for divers bluetooth too) and then just update to 297 driver through Device Manager.

I hope this solution helps someone else; because HP does not have any solution at all.

    Have installed the latest driver for 64-bit windows 10 of Qualcomm-Atheros site. 10.0.0.329 driver version but it does not recognize my home wifi signal, while it did 2 weeks ago. Apparently some 10 windows update is now conflict with this version of the driver?

    I have the same problem that started after the latest updates of windows 10, I can get my wifi works by doing a full restore but within hours 10 Windows downloads an update, and wifi is lost again.

    I get online answers but do not yet have a solution so attached to the router wired for internet access.

  • Replace the Qualcomm Atheros ar956x in Satellite L50 - B

    Hi all

    I am wanting to change the existing WiFi card in our Satellite L50 - B (Qualcomm Atheros ar956x) due to the limitation of speed of connection 150 Mbps! We have a router AC and I move 800 Mbps!

    I was hoping to use an Intel® Dual Band Wireless-AC 7260 however the cards seem to be physically different.

    Any ideas would be great!

    see you soon

    Scott

    Hello

    Found some details about this Intel WLan card on the page of Intel:
    http://Ark.Intel.com/products/75439/Intel-dual-band-wireless-AC-7260

    + Board form factor: half a PCIe card Mini / m2 (NGFF).

    As far as I know the WLan module that is built into the laptop supports Mini-PCI card format.
    So, you have a miniPCI module.
    But you should consider BIOS support. Not all wireless network cards could be supported by the BIOS.

    I just got a laptop HP 2000-2b43dx last month and had no problem with the connection before fall, but here for the past week or so she did it a lot. It starts to get boring, that's why I'm here.

    If I close my laptop and open it again it will be disconnected and I have to reconnect manually even if I have the settings in automatic mode.
    And every now and then it disconnects randomly, and I have to reconnect again. It's really annoying when you try to play a game and you get kicked out of a game because of that.

    I've updated the network driver and the only thing that helped was able to reconnect faster...
    My old laptop has never had this problem and it only recently started to do a few weeks back.

  • Qualcomm-Atheros AR5BWB222 Wireless Network adapt

    Hello

    I have trouble keeping my brand new Acer Aspire 5600U online.  The Ondaaah continues to go offshore, often.  I know that this is not my router because I never had this problem with the old computer.  Is this a known problem with the Qualcomm Atheros AR5BWB222 ANA, and if so, did someone come with a fix for this?  I saved a paper copy of the information on the diagnosis of the last time that I hit my offline, and

    Yes, that seems to have solved the problem for my Aspire 5600U all-in-one desktop.  The setting in Windows 8 is:

    Control Panel > hardware and sound > Device Manager > network adapters.

    Then choose Qualcomm Atheros AR5BWB222 Wireless Adapter and

    Uncheck the box "Allow the computer to turn off this device to save power."

    I tested this setting for the last few days and have not gone offline once.

    It's a shame that a large number of unnecessary corrections are available, which do not solve the problem,

    and that supported by Acer do not notify customers do, before they try something more radical.

    If I had followed their instructions, I would have ended up paying to ship to Acer for repair.

    and who knows what I would have obtained, since their support does not seem to be aware of this!

    Turning into a computer brand new for refurbished computer from someone else is never going to be a good solution for me.

    Didn't have to pay for shipping repair a computer that should work, out of the box.  Very disappointed in support of Acer.  I doubt I would buy my next computer, now that I know about the quality of their customer service and technical support.

    This solution seems to work fine for a desktop computer, but not so well for a laptop.  Both for the effective management of energy!

    Thanks for the suggestion, finally something that worked!

  • Satellite S50D - A - 10 G - accidentally uninstalled Atheros WLAN driver

    Hey,.

    So, be a fool, I accidentally uninstalled the Atheros driver, and then I noticed that my laptop is therefore more able to detect my WiFi at home. After looking around, online, apparently it's because I uninstalled Atheros? (Sorry, I'm a noob to computer).

    So I try to download the driver for my laptop, but I can't seem to find where to download the driver. My laptop is the Satellite S50D - A - 10 G, and I do not know where to look. I tried to look on the Toshiba.com site, and they said that my serial number was invalid etc..

    Advice and assistance would be greatly appreciated!
    Sorry, I have very little idea of what I'm doing!

    I ve checked the Toshiba download page and found the Atheros WLAN driver.
    You can download it if you visit http://www.toshiba.eu/innovation/download_drivers_bios.jsp

    Please choose your Satellite S50D-A, with the PSKKWE part number and you will find it.

  • Slow WiFi on Qualcomm Atheros AR9485 wireless adapter on HP Pavilion 500-120EA 8.1 Windows

    This wireless adapter is extremely slow that causes ping high during the game. The game I tried was League of legends. The artheros adapter showed the ping MS 1000 +.

    So I decided to see if the necessary driver updated. When you go to Device Manager to update, it showed that she needed no updates.  Also checked on the hp site and it showed that I have the latest version of the driver. So I checked the Atheros website and I didn't have the latest version of the driver. So I intalled the latest driver at 10.0.0.263 10.0.0.270.

    Yet once I tried the game to see if there is an improvement with Internet and again he showed my ping 1000 + Ms. has not changed at all. No improvement.

    I did troubleshoot and it sort of something I do not know what but. No change.

    I also changed the powersaver maximum for the wireless card. No change.

    Several times I looked at task manager network, it shows send and receive to be at 16/08/32 Kbps or sometimes even zero Kbps. The table looks very small and its value on the chart was of 100 Kbps.

    However, I don't see a difference during the videos to youtube or browsing the Internet. Here, the speed is very good. Even during the speedtest, speed showed a ping from 43ms. sending / receiving packets are indicated in 00' sKbps Mbps. The table is not stable it flucatuates strongly.

    So I change my card a blekin N300 wireless and all the problems I've had are solved. The ping playing League of legends is 40-70 m send it / receive packets similar to the atheros AR9485 rae but I've seen go up to 88 Kbps at its highest level.

    So what can I do to fix the Qualcomm Atheros AR9485 wireless adapter?

    Any help is appreciated.

    What can I do else?

    Just an update to someone else who has had this problem for the channel 11 wireless channel setting should do the trick.
