Hi so the internet seems to be working fine on every device except my laptop. Sometimes it would even stop showing the available networks. I recently switched to ubuntu and this used to happen on windows too but a simple reinstallation of wifi driver or renabling the wifi driver after disabling it would solve the issue.

Possible solutions I am looking for:

1. Is there a device manager utility in ubuntu like in windows where I can disable/enable drivers or reinstall them? If not then

2. How to disable wifi drivers in ubuntu?

3. How to reinstall/uninstall wifi drivers?

Edited to add the output of lspci -knn | grep Net -A3

  • Have you tried toggling the hardware switch or button that controls wifi? – xiota Nov 4 '20 at 10:53

This wireless device "QCA9377 802.11ac Wireless Network Adapte" is supported by Linux kernel and does not require any drivers.

Problems with your wireless device may be caused by a kernel bug, a hardware problem, or other reasons.

If this happened on Windows too, it means that most likely it is a hardware issue.

You can reload the in-try driver by running:

sudo modprobe -r ath10k_pci
sudo modprobe ath10k_pci
-1
terminal:
rfkill list
Example:
rfkill list
0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
Turn OFF WiFi
rfkill block wifi OR using “rfkill list” index rfkill block 0
Turn ON WiFi
rfkill unblock wifi OR using “rfkill list” index rfkill unblock 0 

How can I bring back disappeared or hard-blocked wifi on linux?
