Authorization supplicant timed out error / Connection gets lost and reconnects again

Hello,

i have some WiFi problems with my PC since im using Manjaro. First i was using the build in Intel Centrino Wireless-N 2230 WiFi Card. But i had a terrible download rate after some minutes of use, the related thread can be found here: WiFi suddenly gets slow / after reconnect its fast again

So i decided to buy an USB WiFi adapter and disable the Intel Card, but after some browsing my connection disconnects, then reconnects and the message Authorization supplicant timed out error appears. It happens randomly, i cant reproduce it.

Ok some facts:

I found something simmilar here on manjaro forums, but i have no hidden ssid:

I disabled the internal intel wifi card by blacklisting iwlwifi module:

cd /etc/modprobe.d
sudo touch blacklist.conf
sudo nano blacklist.conf
blacklist iwlwifi 

And set the Region to Germany

sudo iw reg get
sudo iw reg set DE

cd /etc/conf.d
sudo nano wireless-regdom
=> removed the # in front of WIRELESS_REGDOM="DE" and saved it.

And now im out of knowledge what causes this issue. Does anybody have an idea?

a few things:

Have you verified that this actually worked?
Because the syntax is incorrect - there should not be any quotation marks in there.
The content of that file should now be this:

blacklist iwlwifi

test with:
cat /etc/modprobe.d/blacklist.conf

again, to check what is now not commented out in that file, use:
grep -v ^# /etc/conf.d/wireless-regdom

it should return:
WIRELESS_REGDOM="DE"

But that setting is really not important.

Lets actually see whether what @cscs recommended was actually implemented and whether it is still there or not:
cat /etc/modprobe.d/iwlwifi.conf
cat /etc/modprobe.d/iwlmvm.conf
just to make sure there where no syntax errors (see above - no quotation marks)

comment out
/etc/modprobe.d/blacklist.conf
by putting a # mark in front of the line to again test it
… else the module will not even get loaded

Hi thank you for your answer.

My blacklist.conf is correct, the quotation marks are copied from my internal documentation, but the file i’ve set is correct.

cat /etc/modprobe.d/blacklist.conf

blacklist iwlwifi

My region set should be correct aswell:

I have no iwlwifi or iwlmvm.conf file in this directory /etc/modprobe.d/, but out of my understanding i dont need them, because i disabled iwlwifi module?

I was referring to your other post,
where you where given the recommendation to create these files
as they activate certain options within the iwlwifi driver that might be helping to mitigate your problem with your built in card.

It wasn’t very clear to me that that was thoroughly tested.
But it probably was - and now you have the very same symptoms with a different wifi device.

I’d check for any power saving software and disable it entirely (temporarily, for testing purposes).

tlp came preinstalled and activated in some, if not all, Manjaro editions - but it is not always correctly configured and can cause symptoms like this.

systemctl status tlp
if it’s running - stop and disable it … for now

or at least re-check the configuration to make sure that USB devices and network related hardware are excluded from power saving measures

That would be my next step before blaming and trying to find fault in the new wifi driver.

I filtered logfile to errors and other system messages and this is what i get:

=> 88x2bu: loading out-of-tree module taints kernel. Is this relevant? After i exported this logfile i already had such an timeout error.

no
It’s just a message about the license of that module being incompatible with the GPL (the license of the kernel)
it’s not about functionality
… you could google the term “loading out-of-tree module taints kernel” to learn what it means …
I don’t quite get why you posted this log - and why you chose to filter it like you did.

What about tlp?
Has it made any difference?

Ok thank you. I posted this log to be sure, that there are no errors in hardware or kernel. And its part of the “[[HowTo] Provide System Information]” thread. So i thought its helpful.

I disabled usb autosuspend in tlp with

/etc/tlp.conf
# Do not suspend USB devices
USB_AUTOSUSPEND=0

now im waiting if the problem still persists.

//EDIT: Problem is still there as feared

information gathering
next up is NetworkManager
and it’s configuration
Do you use it?
I have had similar problems myself with some routers at some places.

have a terminal open and in it run:
journalctl -f
to observe the messages as your issue occurs

also try using
sudo dmesg -w
in the same way - it seems to be more verbose

Of course all that is already in the logs, but may be hard to find.
journalctl -b0 | grep NetworkManager
to find the timestamps around which to look
then look at it at around that time without the filter
journalctl -b0

-b0 is the current boot - use a number to refer to previous boots

Thank you, i installed Kubuntu for testing purposes to be sure, that this problem has nothing to do with Manjaro / Arch Linux. On Debian (Kubuntu) i have the same problem with these disonnections.

I was able to save a Log when the disconnect happened. But i dont get whats happened there? I fear its a driver problem, isnt it?

I don’t think it’s a driver issue.

I had problems like this with one network at a place I was staying at.
It prompted me to read up on NetworkManager and it’s various default options.

What I have got now in /etc/NetworkManager/NetworkManager.conf is this:

# Configuration file for NetworkManager.
# See "man 5 NetworkManager.conf" for details.

[device]
wifi.scan-rand-mac-address=no

[connection]
# wifi.cloned-mac-address=preserve
wifi.cloned-mac-address=permanent

Basically, I disabled the default behaviour of scanning with an ever changing (fake) MAC address
in favour of using always the same.
Some Routers seem to not like this and I don’t care whether I can be identified my my MAC address …

This has made my connection there stable - where before it would take ages to connect and even longer after the connection dropped for some reason.

This setting should be partially available via the GUI
It’s in the Wi-Fi tab (cloned MAC address) of nm-connection-editor

I also disabled IPv6 since I don’t need it and to exclude another layer of possible reasons for problems.

I disabled ipv6 in KDE connection settings and set, that my SSID is only restricted to connect with the wlxe84e069973f8 adapter. ( the onboard intel card is still running but not connected)
I dont know how its called in english, i think "restrict on device or similar.

Also i added the option

[connection]
# wifi.cloned-mac-address=preserve
wifi.cloned-mac-address=permanent

to my NetworkManager.conf file. The device entry was already there.

It was? I thought I at least changed it from yes to no …

I do not use KDE, but Xfce - but the Network config should be the same since both use NetworkManager.

I do not quite know what that means.
You can restrict the scan to a specific MAC (that of your router you want to connect to)

We are not supposed to write in german in an english forum - but you could … :wink:
(I thought I saw something hinting at this in the log …)

In addition I just saw that you seem to use systemd-resolved for a DNS resolver
(not entirely sure)
I use dnsmasq myself, because it provides caching and is therefore faster (for me).
Here are the relevant items in the Arch wiki:

NetworkManager - ArchWiki

NetworkManager - ArchWiki

(the links look the same - but go to different places in the main article)

The onboard device is there again, because of my (Kubuntu) reinstallation. To disable it didnt solved my issue, these devices are not affecting each other so i leave it enabled for now.

My current settings:

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false

[device]
wifi.scan-rand-mac-address=no

[connection]
wifi.cloned-mac-address=permanent

Thense are my current N Manager settings:



I will take a look into dnsmasq, thank you for this. :slight_smile: I will test if my connection is running now with the new NetWorkmanager.conf settings. I will keep you informed :wink:

Sorry for late response but the problem still persists.

I think its the driver, because the 2,4 Ghz wifi has a stable connection. The wifi i tried to get a stable connection is 5 Ghz :confused:
