I can't connect wifi after upgrade

I installed ubuntu-mate-20.10-desktop-arm64 + raspi.img.xz on raspberry pi cm4. Everything worked fine include wifi. But after system update and upgrade wifi is not accesible. I check network interface and wlan0 was not listed. It just lists eth0 and lo. How can i solve this problem.

Linux my-desktop 5.8.0-1021-raspi #24-Ubuntu SMP PREEMPT Tue Apr 13 11:00:57 UTC 2021 aarch64 aarch64 GNU/Linux

Welcome, @Burak_Kocaman, welcome to the forum.

Try rebooting. If the upgrade updated your kernel, then there's no guarantee that the new kernel modules that were installed are compatible with your incumbent kernel -- in fact, it's very unlikely that they are.
