    QCA9377 Unstable WiFi connection on Ubuntu 16.04

    Hey!

    I have a problem with Wi-Fi on a Dell laptop with a Qualcomm Atheros QCA9377 802.11ac wireless network adapter.
    WiFi somewhere every 5-10 minutes just stops receiving and sending data. I can not connect to the router (192.168.1.1) too. If I just reconnect to the hotspot, then the next 5 minutes Wi-Fi is working.
    With ethernet everything works without issues. On the second OS win10, wifi also working without issues.

    I tried this: https://ubuntuforums.org/showthread.php?t=2355396 , but nothing has changed.


    Result of wireless info script : https://paste.ubuntu.com/p/dxcBcJxz7W/


    Does anyone have any ideas on how to fix this annoying problem?

    Go into the router settings, and set it to channel 9 rather than auto, and set the bandwidth to a setting other than auto
