    Wireless network too slow and unreliable


    I am dual-booting Windows 10 and Ubuntu 20.10 in my laptop and I have a wireless network issue in Ubuntu. The internet speed is too low compared to Windows 10. I only reach Kbps in Ubuntu while in W10 it's always Mbps. Besides the speed, the connection breaks every now and then in Ubuntu. The status bar shows I am connected to the internet but both my upload and download speed falls down to 0. I found other people were having similar issues with Ubuntu 20.04 and the fixes they suggested didn't work for me. Has anyone faced the same issue and found a fix yet?

    I doubt if you will get any help without posting some details. Run the commands below and post the output here.

    lspci | grep -i wireless
    Have you gone through the wireless troubleshooting documentation at the link below?

    If you have inxi installed, running the command: inxi -N will give the network card and driver info.

    The command lspci | grep -i wireless doesn't return anything. However, I ran lshw -C network and got the following details

    description: Wireless interface

    The troubleshooter is basic and doesn't list my problem.
