Wifi desconectando no notebook

Bom dia a todos, eu senti que depois de muito atualizar o kernel e até mesmo quando fui usuário do windows tive problemas com o wifi na própria máquina. Outros dispositivos funcionam na mesma rede normalmente, quero levantar os diagnósticos para que possam me ajudar, não sei qual os procedimentos para o tal, quais os procedimentos simples para começar? Conto com ajuda de vocês, pois wifi tá saindo muito seguida, obrigado!

com o comando watch -n1 iwconfig você consegue monitorar o link on line... acompanha por um tempo, vê se perde sinal....

com o comando journalctl -u NetworkManager você vê os logs

Boa tarde, logzinho de hoje galera :P
Mais uma queda... alguém se souber me informar como posso ver as mensagens que aparecem quando o linux é reiniciado, lá percebi que da várias mensagens de erro relativos a wifi , mas passam muito rápido para ter mais informações, se alguém pensar em tcpdump ou wireshark eu sei quase pouco eu posso colaborar com esse desafio rsrs.
