Meu laptop é o HP 250 G4 P5T98ES
Meu sistema operacional é: Debian jessie 20160917
Enquanto eu estava instalando o Debian do live-usb, ele me disse que ele não pode se conectar à rede sem fio porque não tem drivers não-livres.
Então eu decidi instalar o driver mais tarde. Eu baixei o driver wireless do site debian (na verdade, eu baixei o pacote inteiro de firmware não-livre.
Então eu corro o comando no terminal no modo su:
dpkg -i firmware-brcm80211_0.43_all.deb
A saída informa que ela foi instalada com sucesso (ou algo parecido). Então eu corri:
dpkg -l firmware-brcm80211
E isso me deu a seguinte saída:
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name Version Architecture Description

ii firmware-brcm80211 0.43 all Binary firmware for Broadcom 802.11 wireless cards
Eu reiniciei o sistema, mas nas configurações de rede ainda vejo apenas duas opções: com fio e proxy de rede.

PROBLEMA RESOLVIDO instalando o debian a partir da versão live-cd que possui firmware incluído. Agora eu tenho meu wi-fi.
