Hello,
I have Acer VN7-791G-51PZ with Atheros QCA61x4 WLan +Bluetoth chip. It does not work well on Windows 10. Unable to get full wifi speed if I use 2.4Ghz band. There is no problem with 5Ghz sometimes its disconnect. I think driver is old. Is it possible provide latest driver?

    I believe the latest driver is dated late 2016.

  • Does the same problem occur when you select channel 36 on the router for the 5ghz band?

    Does the same problem occur when you select channel 36 on the router for the 5ghz band? Also, did this problem occur after upgrading windows to version 2004?

  • OK! Does the same problem occur when changing the channel to 36 on the router?

    In the USA the available bands are 36-50, which corresponds to 5.15GHz to 5.17GHz. Mine is set for an 80MHz width on channel 42, which is as fast as we can go and stay in the allowed range. If you drop down to channel 36 as suggested it forces the width to be the minimum 10MHz and tells us if the problem is noise from other systems, since very few only use that lowest channel.
