Isn’t it today that my wifi has some problem with Manjaro
But this time I’m not sure if it was some configuration I made or just a bad route from my internet provider
The posts were deleted, but I had already reported problems with previous versions of Manjaro. The solution was to configure the system to ignore IPV6.
Actually wifi without IPV6 is more stable, if I set on automatic wifi does not work, because it falls at all times
My network doesn’t have IPV6, I can certify that because I checked the network with another notebook with windows and smartphones too. But I don’t use it.
There’s something in Manjaro that makes the connection drop all the time. I suspect IPV6 but it could be anything, the Qualcomm Atheros card doesn’t have many positive feedbacks…
If someone can help me I’m grateful

To disable IPv6 completely just add this to boot params:
ipv6.disable=1
2 Likes
cscs:
ipv6.disable=1
In /etc/default/grub or /etc/sysctl.d/40-ipv6.conf like here ?

in /etc/default/grub on the GRUB_CMDLINE_LINUX line then runsudo update-grub

Setting GRUB_CMDLINE_LINUX="ipv6.disable=1" solves the issue, I tested for hours and drop only one time.

Good to hear.
In file /etc/modprobe.d/ath9k.conf (create if not present)
options ath9k nohwcrypt=1
This command would do it in one shot:
echo -e "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf
Explanation:
Reason: Just gave better results. Normally I chase ‘hardware acceleration’ on everything else. But finnicky radio cards? … no. If they are weird and we can offload the work it usually ends up better.
This is one parameter I already set up in last post ‘-’. So this is already created. By the way you help me in that post LoL
That’s it, problem solved! Some “networks features” for me, get in the way than help.

After some more tests, I confirm some instability with the system. Randomly there is still a drop. Can be my wifi card?

Possible.

Hm. OK … 2 more module options that might be somewhat helpful:
bt_ant_diversity=1 ps_enable=0
(you can add them to the same options line in the modprobe file like above with nohwcrypt)

Got it, I added the parameters and rebooted in the line, I’m checking if it will happen again.
so I thank you for your quick response and help
Yes, I’ve read the documentation, so I assumed at first that one of the prime suspects is the IPV6.

like here ?
this article is what I quoted above
but can be other things like ISP , router or card. If you are interested this is the old post that I related in old manjaro version
But this last parameter maybe can solve this issue definitely, i need to test first
didn’t work , same thing happened
re-reading the old post I did, I’m not surprised I didn’t get a positive result
it is really being difficult to perform remote activities with this kind of stability that Atheros is performing
Using dmesg I encontred this errors:

this is definitely related to what’s happening
In Live USB (manjaro 20.0.3) the WiFi seems to not drop
