Please, follow the template and post garuda-inxi.
And reboot or update.

Does your university by any chance make use of the eduroam roaming service?
I guess not, otherwise it shouldn't have worked before, but just in case it does, look here:

No, my University does not use eduroam.
i tried rfkill it showed me unblocked.
another thing i forgot to add was that after typing the password it will try to reconnect and again ask for password in a pop up.[Also my friend use manjaro for him also it the same before update it was working fine after the update he also has the same problem like me ].
Could you kindly assist me? I'm more than willing to provide any necessary information.

Try restoring a snapshot from before the update to confirm it is an issue related to this update.

Try also installing the LTS kernel, which is on a different kernel release and will have a different version of drivers for your network card.

I created a snapshot named " before update"
After the update the wifi problem started ,so when i rolled back to "before update " the wifi was working fine

The most likely culprit for the network breaking on an update would be the kernel. A couple very simple things you can do off the top of my head:

  1. Stick with the system that has been restored, and hold off on taking an update for a couple weeks. As long as you don't need to install any new packages in the meanwhile, there is nothing wrong with putting off your update for two or three weeks. After the kernel has been updated, check again to see if the issue has been resolved.

  2. Try your luck with the LTS kernel, which runs a different kernel version and has different drivers, modules, etc built in to it. This may be a better option if you need to take down the update for any reason, including installing new packages.

To install the LTS kernel, first take the update:

garuda-update

Then install the kernel and headers:

sudo pacman -S linux-lts linux-lts-headers

When your system is booting up, you can select an alternate kernel from the advanced options in the Grub menu.

I download the LTS kernal, but still the wifi is not connecting.

So i should roll-back to "before-update" and wait till 3 or 4 weeks

9

Just downloading the kernel is not enough--you need to reboot, and specifically boot with the LTS kernel by selecting it in the advanced boot options in the Grub menu.

If you update and boot with the LTS kernel and it doesn't work, it's possible another package (besides the kernel) is to blame. :thinking:

In the above message i downloaded and rebooted into lts.

The following command will output a list of packages that were updated on your system recently that can affect networking:

cat /var/log/pacman.log | grep -i "d systemd (\|ed linux\|mware\|twork\|dkms ins\|a-nm\|nm-c\|ufw\|dhc\|dns\|wpa\|vnc\|ifplugd\|regdb" | grep -v "head\|nvidia"  | tail -n 30

Please post the output returned.

You could try systemically downgrading each package on the list to determine which package upgrade was responsible for your network breakage.
