Which of these methods do you use to manage your network connection?

https://wiki.gentoo.org/wiki/Network_management#Comparison_of_network_managers

The wpa_supplicant mechanism is used by the client to authenticate with the
wireless AP irrespective of the method you use to control the rest of the
network stack.

How do the network drivers differ between the two kernel configurations?

Have you changed anything else in your configuration?

Do you run the rtl8723bu in AP mode too?

Have you blacklisted the wireless driver rtl8xxxu mentioned in the GIT page?

As long as you've kept the kernel image and initrd (if you're using one) then
you can carry on booting with it, while trying out later kernels. Also keep
your working kernel .config file to be able to run 'make oldconfig' with newer
kernels and to also to be able to compare differences between kernel releases.

6.1.67 was an emergency release to fix one single issue related to wifi:

https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.1.67

Thank you both for replying quickly.

Michael, the driver does not seem to differ and nothing has changed in my configuration. rtl8723bu is not, to my knowledge, run in AP mode. I have blacklisted rtl8xxu. Also, I use NetworkManager.

Nikos, thanks for the link ! Updating to 6.1.67 solved my issue.
The update seems to have been made very recently, so thanks to the gentoo dev too.

Best,
