My wifi connection keeps disconnecting frequently (say once in a couple of minutes) sometimes it gets back and sometimes I need to activate and deactivate aeroplane mode.
I tried to change my network provider to make sure it is this laptop problem and not the internet I use. The same happened with ADSL connection, android hotspot, and TD LTE modem.

Here is Solutions:
We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.
Had the same bug (same wifi chipset, but in an old Toshiba) after installing Ubuntu 22.04.
Appears to be a bug in the 5.15 kernel, and solved by installing the 5.17 kernel.
I did the following :
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.17.5/amd64/linux-headers-5.17.5-051705_5.17.5-051705.202204271406_all.deb wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.17.5/amd64/linux-headers-5.17.5-051705-generic_5.17.5-051705.202204271406_amd64.deb wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.17.5/amd64/linux-image-unsigned-5.17.5-051705-generic_5.17.5-051705.202204271406_amd64.deb wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.17.5/amd64/linux-modules-5.17.5-051705-generic_5.17.5-051705.202204271406_amd64.deb sudo dpkg -i linux*.deb
Then I rebooted, and wifi works fine now.
Similar behavior, wifi keeps disconnecting and malfunction
my hardware : laptop Asus N751JK
Network controller: Qualcomm Atheros AR9462 Wireless Network Adapter (rev 01)
Subsystem: AzureWave AR9462 Wireless Network Adapter
I was runing Ubuntu 20.10, 21.04 up to Ubuntu 21.10 with Kernel 5.13.0 without any problem.
I migrated to Ubuntu 22.04 which installs Kernel 5.15 then the problems started.
I upgraded and tested unsuccessfully the following Kernels : 5.15.28, 5.15.36, 5.16.14, 5.16.20, 5.17.4, 5.17.5
I disabled the power save as explained without improvement in any of the Kernels tested.
Also the "intel_iommu=off" mentioned at https://groups.google.com/g/linux.debian.kernel/c/RFpPIp0cncA/m/v9ELDxLICgAJ Bug#994590 didn’t help.
I downgraded and currently running without any problem using the Kernel 5.13.19-051319-generic.
There is no problem in my airpoint (router) nor my internet access, I have other different computers and devices working correctly on wifi. In addition the N751JK works correctly when using the Ethernet adapter for the physical cable.
sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/*
P.S: By the way, when I have set power mode to balanced in power settings, why there must be a power saving setting like that enabled?
sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
And change wifi.powersave to 2
So I tried all of the solutions listed here, however, what worked me was upgrading the Kernel to 5.17.14-051714-generic. It’s been working for about 30 minutes. I will update this thread is the issue persists. Fingers crossed!
My specs: Clean install Ubuntu 22.04.1 with Intel Wireless PCI-e card.
I tried most of the answers above, some of them worked but the problem started again after a couple of hours. Finally I installed a fresh Ubuntu and get rid of the disconnection syndrome but the same thing started to happen the day before yesterday.
At last my searches led to a bug with the 5.15 kernel and I found that there are many people facing the same problem with 5.15 and 5.16 kernels. I just updated to the latest kernel (5.17.7) and it has solved the problem for two days now.
I tried this solution to update to the latest kernel
i had an old machine with (linux ubuntu lts 22.04) internel wifi hardware named intel corporation centrino wireless-n 1000 condor peak. i had tried all methods, installing differnt kernels, but nothing worked me. after rigorous research i found this thread https://ubuntuforums.org/showthread.php?t=2274336.
Steps to follow
- Go to wifi settings
- Go to ipv6 tab
My wifi is much much faster, Full speed and No slow browsing
reply and give a thumbs up, if this works for you
Probably not a solution, but helped me.
- Being on
DELL Precision 5540/
- after multiple upgrades and downgrades
- trying kernels
i became desperate and started writing a re-connecting script, following How to connect and disconnect to a network manually in terminal?
But as soon as i tried the first command to connect from terminal:
$ nmcli device wifi connect MY_SSID password "MY_PW"
The connection became stable and not interrupting any more!
after installing the 5.17 kernel there may be a problem with updating the program core and the appearance of the message system:
error: bad shim signature.
error: you need to load kernel first.
press any key to continue…
it can be fixed by disabling secure boot from BIOS
Note: Use and implement solution 1 because this method fully tested our system.
Thank you 🙂
