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.
To be more specific, please include this commit:
https://gitlab.com/kernel-firmware/linux-firmware/-/commit/0a18a7292a66532633d9586521f0b954c68a9fbc
And possibly also this:
https://gitlab.com/kernel-firmware/linux-firmware/-/commit/1366b827c21351b37665303397e161dd4158316e
Thanks!
We also need:
1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
Ubuntu 22.04.3 LTS
2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
ii linux-firmware 20220329.git681281e4-0ubuntu3.24 all Firmware for Linux kernel drivers
3) What you expected to happen
WiFi working
4) What happened instead
Multicast packets dropped, mDNS not working |
[SRU Justification]
BugLink: https://bugs.launchpad.net/bugs/2049220
[Impact]
MT7921 - IPv6 no longer working (Not receiving Multicast).
[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.
