As per https://bugs.launchpad.net/bugs/2049303 - another workaround for Ubuntu 22.04.3 LTS is switching to the 6.2 HWE Kernel.
For me, I noticed the issue after my system got updated from the 6.2 HWE kernel to the 6.5 HWE Kernel. Rebooting the system back to the previous 6.2 HWE Kernel resolved the problem. Note that both kernel images leverage the same firmware version as that's provided via the linux-firmware package: mt7921e 0000:05:00.0: WM Firmware Version: ____010000, Build Time: 20220209150915 So something specific with the 6.5 HWE Kernel module mt7921e in combination with this specific firmware version breaks multicast. Seen that updating the firmware image resolves the issue, it points to a bug in the firmware and not the kernel module. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/2049220 Title: Update firmware for MT7921 in order to fix Framework 13 AMD 7040 Status in linux-firmware package in Ubuntu: In Progress Status in linux-firmware source package in Jammy: In Progress Status in linux-firmware source package in Mantic: In Progress Status in linux-firmware source package in Noble: In Progress Bug description: The current firmware for MT7921 WiFi is giving me problems like dropping multicast packets (mDNS).
