    Hi,

    I have installed Deepin on a Dell XPS 9560.
    Most things work perfectly out of the box and I realy love this distribution so far.

    However I have an issue with the wifi card.
    It won't go higher than 54Mbit/s.
    With other distros (manjaro/ubuntu) it does go higher.
    I tried multiple AC accespoints which can go over 100Mbit/s easily.
    I check the speed with the Deepin control center and with wavemon.
    They both give an upload and download speed of 54Mbit/s or lower.


    This is the network card type:

    1. lspci | grep -i Network

      02:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)

    Copy the Code

    And the Deepin version number:

    1. ~ lsb_release -a

      No LSB modules are available.

      Distributor ID:        Deepin

      Description:        Deepin 15.9.1

      Release:        15.9.1

      Codename:        unstable

    Copy the Code
    I tried searching for Debian and Deepin issues for this network card but could not find any similar issues.

    I'm kind of stuck as I don't know how to proceed in fixing this.
    Do you have any pointers for what I can do next?

    Is it for example possible to install a newer kernel?
    From what I've red on this forum thats not supported, is that true?

    Thanks for your help,
    Joep

    Try this:

    # nano /etc/modprobe.d/iwlwifi.conf

    Put a # in front of the following line:

    options iwlwifi 11n_disable = 1 bt_coex_active = 0 power_save = 0 swcrypto = 1

    Add this line below:

    options iwlwifi 11n_disable=0 bt_coex_active=0 power_save=0 auto_agg=0 swcrypto=1
