Sem fio parou de funcionar de repente

1

O wireless no meu computador parou de funcionar, embora eu tenha conectividade. Não consegui encontrar respostas que resolvessem o meu problema, por isso estou a abrir esta questão. Eu espero que seja consertável. Aqui estão algumas informações que achei que poderiam ajudar:

sudo lshw -c network

Então, basicamente, a verificação retorna vazia (mas deve ser porque eu posso acessá-la no meu telefone, por exemplo).

memo@poc:~$ sudo iw dev wlp3s0b1 scan
memo@poc:~$ 

Obrigado a todos pela sua ajuda e, por favor, deixe-me saber se devo fazer outra coisa
