Wifi incredibly slow on Dell XPS 15 laptop running Arch

Hello everyone

I am new to Arch. I have a Dell XPS 15 laptop running Arch. It is not a dual boot setup, I only have Arch on the laptop.

On the laptop, Wifi is incredibly slow (sometimes 0.5mbps speeds), often when I run

sudo pacman -Syu

it won't complete, and would error out due to "failing to retrieve file" issues. I'm paying for 100Mbps and I get that on the desktop.

On my desktop, which is also running Arch but connected to the internet via an Ethernet cable, I get the following speeds.

For this boot, here's the output of the journal.

Why is this happening? I suspect I'm at fault, so would appreciate any help.

Re: Wifi incredibly slow on Dell XPS 15 laptop running Arch

Looks like you use network manager & wpa supplicant, but no sign of other network influencing stuff except dockerd .
Does it help if you disable / stop docker ?

What is your linux-firmware version ?
Check https://wiki.archlinux.org/title/Networ … ss#iwlwifi for things to try .


Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
Did you use the guided installer ? If yes, I can't help you.

Re: Wifi incredibly slow on Dell XPS 15 laptop running Arch

Do I need wpa_supplicant if I have network manager?

Means

pacman -Qi linux-firmware

You need wpa_supplicant or iwd to establish a wifi carrier (and afaik NM only supportd wpa_supplicant atm)

Your problem is the enormous amount of

Re: Wifi incredibly slow on Dell XPS 15 laptop running Arch

Ok, so adding:

options iwlwifi 11n_disable=1 swcrypto=1

To `/etc/modprobe.d/iwlwifi.conf` (had to create that file) doesn't seem to have an effect. I'll try disabling MAC address randomization as suggested by seth. I'll report back.
