Meu WI-FI no Ubuntu desconecta recorrentemente e não sei o que fazer.

Recentemente, formatei o PC duas vezes e mesmo assim o problema volta a surgir.

Boa noite,

A primeira coisa a fazer é reconhecer sua placa. No terminal, digite:

lspci -k

E coloque aqui os resultados.

E aí, alguém pode ajudar?

Buenas.
Tente aí uma coisa que não garanto que vá funcionar, mas não custa tentar:

# systemctl enable dhcpcd
# reboot

Deu essa mensagem de erro:

Failed to enable unit: Unit file dhcpcd.service does not exist.

Então, instale o dhcpcd.

Instale o dhcpchd e quando apliquei o comando #systemctl enable dhcpcd, deu a seguinte mensagem:

dhcpcd.service is not a native service, redirecting to systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable dhcpcd

e solicitou a senha três vezes.

O que isso significa?

Cara, isso é totalmente fora do esperado. Nunca aconteceu para mim. E, já usei muitas distros baseadas no Debian (dhcpcd5).
Hoje resolvi o mesmo problema de queda, mas com cabo. Pode ser que te ajude.
Vai nas configurações de rede e desabilita tudo que não for o IPv6. Desabilitei o IPv4 e a conexão parou de cair.
