Network Manager doesn't work properly

My particular wifi network doesn’t work properly on my laptop which goes connected and get disconnected continuously.

Here is my log

Are you dual booting with Windows? If so make sure you boot into Windows and disable the Fast Startup feature in power management.

No I haven’t use windows at all…

Is this on Ethernet or WiFi? Post the following

inxi -Na

I am using wifi

Is there any network Manager update on today’s update

Does your Ethernet work? I see no driver loaded. I wonder if that has any affect to the network manager.

 Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet
    vendor: Dell driver: N/A modules: r8169 pcie: gen: 1 speed: 2.5 GT/s
    lanes: 1 port: 3000 bus-ID: 01:00.0 chip-ID: 10ec:8168 class-ID: 0200

This may require the r8168 package. As far as the WiFi ath10k_pci

Edit: It could be a firmware issue or power management?

Did you try installing the r8168 package and see if it shows the driver loaded for ethernet with inxi -Na

Yes I have install r8168 driver successfully but the problem still persists I have checked powe management in bios then also no use.

Here is the output for inxi -Na command

Are you connecting to 2.4 Ghz or 5.0 Ghz to the router? Could also try a different channel.

How to check that

What does this show


Edit: Can also check frequency with

sudo wpa_cli status | grep freq

You could try the following using nano to create the file

sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-off.conf


wifi.powersave = 2

ctrl + o then enter to save
ctrl + x to exit nano

Restart network manager

sudo systemctl restart NetworkManager
