Yakın zamanda çekirdeğin 5.4 serisinden, 5.8 serisisine geçiş yapmışsın. Belki sorun bununla ilgili olabilir. Ama bununla ilgili bir şey yapmadan önce, aşağıdaki komutlarla ağ yöneticisi için kablosuz aygıt güç yönetimini pasifleştirmeyi deneyebilirsin.

Kod:Panoya kopyala

echo -e '[connection]\nwifi.powersave = 2' | sudo tee /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Kod:Panoya kopyala

sudo service network-manager restart

Sorun yukarıdaki şekilde çözülmezse, aşağıdaki komutla Firmware sorunu için geçici bir düzeltme uygulamayı denersin, ardından sistemi yeniden başlatırsın.

Kod:Panoya kopyala

sudo ln -s /lib/firmware/iwlwifi-cc-a0-55.ucode /lib/firmware/iwlwifi-cc-a0-56.ucode

İwlwifi-CC-A0-56.ucode isimli herhangi bir Firmware Linux-Firmware kaynak sayfasında dahi yok, sanırım mevcut çekirdek ile ilgili bir bug var. kernel/git/firmware/linux-firmware.git - Repository of firmware blobs for use with the Linux kernel

Daha da olmazsa, sistemini çekirdek 5.4. X serisi döndürürüz.

Merhaba, ilk kodları çalıştırdım. Şu an için bir problem yaşamıyorum. Teşekkür ederim.
