I have a USB drive with Manjaro Gnome installed. Its fully updated, When I boot using this USB on my Dell Latityde 7390 the wifi is very slow. It can drop down to just a few Mb/s
Booting on a Manjaro Gnome iso I get full speed 100/10
Looking at inxi -F i get this on my USB install and when booting the iso:
Device-2: Intel Wireless 8265 / 8275 driver: iwlwifi
Hi @niclasc,
I do not know what kernel version are you using, but you could post the output of inxi -Fazy on this post, in order to receieve help from the forum users.
Meanwhile, you could read the following post. https://forum.manjaro.org/t/internet-has-become-very-slow-after-kernel-update/39320
Maybe, there is a persistence problem in your USB.
Please, consider to read the following post: https://forum.manjaro.org/t/problems-with-booting-shutdown-in-a-persistent-manjaro-usb-drive-win-10-situation/38902
Hi @niclasc,
I have no answer at all and instead several questions.
Did you reboot the machine?
Which command or package did you use to make the update?
At last, try with the solution on the following post:
‘Very slow WiFi after recent update [Unstable Branch]’
I updated using package manager and I have reboot more times than I can count.
A clean install using a least a month old iso then the wifi i fine. After an update its broken
In the file /var/lib/NetworkManager/NetworkManager-intern.conf it says “CHANGES TO THIS FILE WILL BE OVERWRITTEN” so why edit that file??
Also that fix is for Realtek RTL8821CE. And I have a Inte card with intel driver
Tried the fix in the link but it did not help. Speed/connection so bad that I cant run the speedtest

None of them helps. I’m at around 1/10 of the speed I should be
sudo sysctl net.ipv4.tcp_ecn=0 gives:

With iso manjaro-gnome-20.1.2-minimal-201019-linux58.iso wifi runs at full speed
But with newest iso manjaro-gnome-20.2-minimal-201203-linux59.iso wifi is VERY slow. Just a few Mbits
Something has changed from one old iso to the latesgt so that affects the speed of wifi
If you suspect the wifi driver, you could check which versions are installed on both.
If they differ you could try downgrade the driver to see if that helps…
Start by using the latest iso
PS:
Just crosslinking Manjaro 20.2 Nibia got released to have this issue linked in that thread.
You might also post something there mentioning this thread so more will notice it…
networkctl --no-pager status -a and look for the line that says Path: in the wifi interface.
fe. mine says: Path: pci-0000:05:00.0
We now have determined that our WiFi adapter is a PCI device at 0000:05:00.0
Next we determine which kernel driver is used for it: lspci -ks 0000:05:00.0
fe. mine says: Kernel driver in use: wl
Next we determine the file used by that driver/module: modinfo -F filename wl
fe. mine says: /lib/modules/5.9.11-3-MANJARO/extramodules/wl.ko.xz
And finally we find which package provides that file: pacman -Qo /lib/modules/5.9.11-3-MANJARO/extramodules/wl.ko.xz
fe. mine shows it is owned by linux59-broadcom-wl 6.30.223.271-10
Thus my Wifi driver is provided by linux59-broadcom-wl with version 6.30.223.271-10
