I examined the packages and I notice the MT7921 firmware (Which confusingly goes by MT7961) is updated but "not" the MT7922 firmware.
Based on the above comments and below finding it seems that the MT7921 hardware is fixed with the update but not the MT7922 (which also confusingly uses the mt7921e driver...). I think it needs to be bumped again to pull in the MT7922 commits.

[Fix] Update WiFi/Bluetooth firmware to upstream commits: * WiFI: commit 0a18a7292a66 ("linux-firmware: update firmware for MT7921 WiFi device") * Bluetooth: commit 1366b827c213 ("linux-firmware: update firmware for mediatek bluetooth chip (MT7921)") [Test Case] 1. Have Ubuntu 22.04 LTS installed on a laptop with MT7921 Wifi adapter and connect it to a Dual-stack network leveraging Router Advertisements for IPv6. 2. Run it with HWE Kernel image linux-image-6.2.0-39-generic and observe the following: - IPv6 stateless autoconfiguration works and a public/global address is assigned. - Inbound IPv6 Multicast packets are seen when using tcpdump/wireshark. 3. Update the HWE Kernel to linux-image-6.5.0-14-generic and observe the following: - IPv6 only configures link-local address (fe80::) and no public/global address. - No inbound IPv6 multicast packets are seen when using tcpdump/wireshark. [Where problems could occur] Opaque binary. No known dependency to kernel version. [Other Info] Nominate Jammy for linux-oem-6.5/jammy and linux-hwe-6.5/jammy, and Mantic. All the commits are in upstream repository, so Noble should have them after rebased. ========== original bug report ========== The current firmware for MT7921 WiFi is giving me problems like dropping multicast packets (mDNS). I manually updated the firmware files and that fixed the issue.
