Estou tendo problemas para fazer o Wi-Fi funcionar no meu antigo laptop Toshiba Satellite (ca 2009). Ehernet funciona bem, mas se eu desconectar o cabo e o computador se conectar a wi-fi, a máquina sempre congelará 1-2 min depois. Wifi parece funcionar bem, caso contrário, como eu sou capaz de navegar na internet até que tudo congela e eu tenho que reiniciar o computador.
Estou executando o Lubuntu (Ubuntu 14.04.5 LTS).
Aqui está o link para as especificações da minha rede:
Eu devo mencionar que eu corri
sudo apt update
sudo apt dist-upgrade
antes de postar sobre este assunto.
Além disso, se isso for útil:

Vejo que há um repo para os códigos de rtlwif mais recentes do Realtek no GitHub ( link ), no entanto, não tenho certeza se isso resolveria o problema ou como instalar o código correto.
Sou novato no Linux. Obrigado pela ajuda!
Eu resolvi o problema contornando-o: eu tenho um adaptador sem fio, neste caso um Adaptador USB de banda dupla sem fio TP-Link Archer T2U AC600 .
Eu tive que instalar o driver que eu fiz seguindo as instruções na parte inferior desta página: Driver usb wi-fi modificado para TP_link TL -WDN5200
Gostaria de mencionar que fui apontado nessa direção graças à resposta do Chili 555 nesta página: Driver TP-Link AC600 no Ubuntu 14.04 LTS x64 . Muito apreciado obrigado.
Que bom que isso seja consertado!
