Qualcomm Atheros QCA61x4A Wireless Network Adapter PROBLEM ERROR (make wifi router down/limited)

edited February 2018 in Nitro and Aspire Gaming

I bought a new laptop this month (ACER VX-15 1050Ti), which has the Qualcomm wifi (Qualcomm Atheros QCA61x4A Wireless Network Adapter) card inside. Sometimes it works for a long period of time and others it will not last 5 minutes. The wifi essentially drops and turns to limited connectivity and requires a troubleshoot to fix. The same error appears everytime which is 'The default gateway is not available - Fixed'. 

I have tried the normal default gateway fixes found on the internet. I have installed numerous drivers and none have so far worked. I have also posted on acer forums (my laptop model) and nobody there has been able to successfully help yet. 

Does anybody here have any ideas/heard of this happening before?

The laptop advertised ultra-fast wifi speed and I've got the exact opposite.

Thanks you all

FAQ & Answers

  • Hi,

    Could you please post the full model name, driver version, in the meantime try switching to different DNS provider, if you are using the DNS from your IPS, try either Google DNS or OpenDNS.

    Go to Network and Internet in Control panel, go to network connections, right click your WiFi, select Properties, highlight Internet Protocol Version 4, select Properties, select the radio button "Use the following DNS addresses", find Open DNS address in my snip, if you want to try Google DNS, Primary: and the secondary:

    Hi Brummy,


    My laptop full model name is Acer Aspire VX-15 591G


    Driver version (Qualcomm Atheros QCA61x4A)


    I'm not using DNS or other DNS (Because I don't understand, and I check all obtain)


    I've tried to set DNS as your direction, but unfortunatery still the same, everywhere I go and turn on my computer, it must be impact the Router/access point hang, limited and cannot deliver internet to all user.


    do you have other solution for this? i read other forum and some laptop users with the same qualcomm type experience the same thing.


    This is very disapointing for laptop with price more than $1000

    One more time, do you have direction to activate gesture on my trackpad?


  • Hi,

    Have you checked whether the Touchpad is in Advanced mode in BIOS? If not, go to BIOS setting(press F2 at start), in Main tab switch to Advanced mode if it's in Basic mode by clicking it.


    Go to Settings, click Devices, select Touchpad in the left pane, scroll down to Advanced gesture configuration.

    Same Issue here with an Acer Aspire VN7-592G also using an Qualcomm Atheros QCA61X4A.
    Does anybody know what could even make a router chrash like this? All devices stay disconnected until router has been resetted.

    First of all, check if there is any driver available install them and restart.

    If your problemm is still not fixed:

    1. Connect to the internet though cable.
    2. Go to device-manager, expand the sector networkadapters, select your network adapter (in this case: Qualcomm Atheros QCA61x4A Wireless Network Adapter), right-click and click on update drivers.
    3. Select the second option (something with search driver from computer) and then click on the option on the bottom of the window (something with list of drivers)
    4. Select the first one and press ''next''. (if there's nothing, check if the option ''show compatible hardware'' is checked)
    5. After its finished, redo steps 2,3 and then select the second one and press next.
    6. If there comes up the restart option do that, if not RESTART manually (don't shutdown and turn on, just restart).

    Your wifi should work now. If not then you should check if the device in you laptop is broken. (don't do that yourself if you dont know what you're doing)
    I had this problem myself and fixed it by this. (took a while to figure it out)

    Hi there - I have a brandnew Acer Predator and have had problems with the drivers running my SIMS3 game. I thought it would help to update the drivers, so I invested in a driver - update program (driver-fighter) and ran a test on it. Updated all 14 updates (on a 2 months old pc!!) and then I could not get on my WIFI. After using oceans of time on fixing this - I just uninstalled all the new updated drivers, and then one by one with a restart on each, found that it was exactly this driver we are discussing here, that was the problem. It will not let me get on the Internet. Very odd???

    I have this exact problem on my Acer tablet "Switch Alpha 12" using the same Network Adapter, running Windows 10. Up to recent days, when the network adapter would fail to connect to the WIFI, I would run the Windows trouble shooting facility to fix the internet connection and afterward the troubleshooter would prompt me to restart the router. This method was working for nearly a year, however, as of today, when the network adapter fails to connect to the router, I have to turn off the router and the computer, wait for more than 30 minutes and then to reboot both the Acer and the router to connect to wifi. The driver has been updated but the problem persists.
    Any suggestion?
    Thanks in advance
