Comment 41 for bug 2049220

I can confirm the fix after applying latest firmware!

ISSUE: I was getting intermittent internet dropping (for 5 to 10 seconds) between my MAC OS and my 22.04 Ubuntu server (no lost of connection from Ubuntu or Mac to internet)

HARDWARE: Motherboard: MSI MPG X670E CARBON WIFI (mt7921e wifi)

IPV6: I noticed missing ipv6 value after 'ifconfig' command (only local ipv6 - fe80)

ENVIRONMENT (after fix): Ubuntu 22.04 (jammy)

$ uname -a
Linux azyri 6.5.0-21-generic #21~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Fri Feb 9 13:32:52 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

HOW TO:
1- wget http://security.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_20220329.git681281e4-0ubuntu3.29_all.deb
2- sudo dpkg -i linux-firmware_20220329.git681281e4-0ubuntu3.29_all.deb

After applying fix:
