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:

lspci | grep -i Network
02:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)

Copy the Code

And the Deepin version number:

~ 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
