Oi, pessoal, venho usando Ubuntu 18.04 há alguns meses, mas desde o último domingo o sinal de wifi ficou fraco a ponto de eu ter que ficar muito próximo ao roteador para conseguir conectar.
Venho buscando soluções mas as que encontrei até agora não funcionaram pra mim.
Esta aqui que se parece com meu caso não teve continuidade: https://www.vivaolinux.com.br/topico/Linux-sem-internet/Sinal-do-Wi-fi-Fraco


A saída do comando lspci é:
