Hi all,
Recently the Wifi connection has been quite unstable, even the signals of the two Wifies I connect are strong. Previously I thought it was the wifi’s problem, but I realised that when my PC failed to connect to the internet, my phone connected with the same wifi worked normally.
If I switch to another wifi, it works sometimes. So the safer way is to disable the wifi and enable it again, but it won’t last long. So I usually connect my phone’s hotspot.
Best,
Wei

Hi @shenwei356 ,
I see this is not your first post, so why didn’t you provide the required information:
From the tutorial: [HowTo] Provide System Information :
Regardless of your problem, always do the following:
Go to the Manjaro forum home page
Choose the correct category
Create a new topic
Describe the symptoms of your issue succinctly simply and shortly.
Go to a terminal by pressing Ctrl +Alt +T , or by going to your start menu and look for something called Konsole
or Console
or xterm
and click on it.
Maximise that black screen (that’s “the terminal”)
If you’re on a non-English version of Manjaro, copy-paste the following:
export LANG=C
and then press Enter
Copy-paste the following:
inxi --full --admin --filter --width
* Please note that by hovering over the above text, a small icon will appear at the end of a single line or at the top right of multiple lines of text.
* Clicking that icon takes care of the copy part already, so you just have to paste it into the terminal by right-clicking on it and choosing <kbd>Paste</kbd>.
* Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command.
Press Enter to execute the command
Now go back to your question and type 3 backticks `
Select, and copy-paste the full output of the inxi
command FROM the terminal TO BELOW those 3 backticks
End the output with another set of 3 backticks.
(your output is now correctly formatted to allow us to help you more efficiently)
text
End your post with an actual question like:
What should I do now?
How should I proceed?
So please, we need the information specified there, starting with:
inxi --full --admin --filter --width
Sorry, I didn’t know that rule. Here are more details:
$ inxi --full --admin --filter --width

According to Qualcomm QCNFA765 Wireless Network Adapter :
The device is supported by kernel versions 5.14 and newer according to the LKDDb
So I don’t know what to suggest, except perhaps trying a different kernel, perhaps 6.1:
sudo mhwd-kernel --install linux61
And reboot into it :
All available kernels installed on your system will be presented upon booting up. GNU GRUB is visible with a couple of options. Choose “Advanced Options for Manjaro Linux” by using the arrow keys ↑ ↓ on your keyboard and then ↵ Enter .
On the next screen (as illustrated) are backup copies of each kernel version installed (which will also be automatically removed if or when a kernel version is deleted). To select a kernel, simply use the arrow keys ↑ ↓ to highlight the desired version, and then press ↵ Enter .
Unfortunately, it does not help. It might be still the wifi’s problem. The Wifi is weak but stable at home (sorry I forgot to mention this.).
Then I can honestly think of nothing further to do, especially if it works even with a weaker signal elsewhere. Makes me think it’s not your Manjaro or even your PC.
Have you tried a different channel, if possible? It could be bluetooth interference (I think.)
Good point, but they are two public WIFIs, which I can’t configure the channel. I reported this to the IT colleagues days ago, while it’s not helpful.
I appreciate your help.
It could also be a poor quality interface; it seems to be an Atheros chipset which is generally good, but it could also be from the lower end of their product line.
Apart from that possibility, and as @Mirdarthos suggests, the cause likely falls back to your environment; which we can’t help much with.
