Como depurar repetidas desconexões Wi-Fi no Arch Linux?

Depois de muito tempo tentando obter uma conexão sem fio , agora consigo uma extremamente superficial (como em alguns segundos de acesso real à Internet a cada poucos minutos). Executando wpa_supplicant -d -i wlp0s29f7u5 -c wifi.conf -Dwextem um VT e while ! yes | pacman -Syu; do :; doneem outro, após vários minutos, ainda não está pronto, mas de vez em quando ele consegue baixar alguns arquivos.

iw dev wlp0s29f7u5 link na máquina Arch relata uma intensidade de sinal de cerca de -40 dB, que é muito pior que o laptop Ubuntu vizinho a -70 dB.

Saída de conexão:

O progresso geralmente faz uma pausa na EAPOL: disable timer ticklinha por alguns segundos antes de continuar.

Alguma ideia do que poderia estar errado? A saída é principalmente grega para mim.

Preciso fazer mais alguma coisa em segundo plano, como renovar a concessão do DHCP, quando a conexão for estabelecida para utilizá-la o mais rápido possível?

E, finalmente, -40 dB é considerado uma qualidade de link "suportável"?

Há várias coisas estranhas acontecendo aqui:

O que é uma "resposta de sinalizador e sonda corrompida" e como corrigi-la?
Por que acha que estou na Polônia quando estou no Reino Unido?
Por que as três primeiras tentativas de conexão sempre expiram enquanto a quarta é bem-sucedida?

Qual é o controlador wifi? Que máquina é essa? Você pode colar a saída de lspci?

Ok, eu acho que o controlador wifi é o problema. Qual sistema operacional você está usando? É archlinux?

— mtahmed

Ok, tanto quanto eu sei, o problema está com os drivers rtl8192c *. Tente instalar o dkms-rtl8192cupacote do AUR e reinicie e tente. Deixe-me saber se isso funciona. BTW, que máquina você está usando? Um laptop?

— mtahmed

É uma máquina de desktop, mas por que isso faria alguma diferença?

Como certas combinações de hardware do rtl8192 são conhecidas por não funcionarem. Você tentou o dkms-rtl8192cumotorista?

O problema são suas configurações de wpa_supplicant; primeiro -Dwext é antigo. use -Dnl80211 segundo; não adicione nada além de net.lo e net.wlp0s29f7u5 ao seu script inicial e adicione-os no momento da inicialização para carregar. terceiro; remova qualquer coisa como o NetworkManager ou o Wicd quarto; Limpe seu arquivo de rede e config_wlp0s29f7u5 = "dhcp" para ele. isso será útil se você usar o dhcp na sua conexão WIFI. também em seu terminal com o tipo de acesso de superusuário dhcpcd . apenas por diversão; isso pode resolver muita dor

também verificar o seu kernel para suporte Dnl80211 e seu módulo de placa Wi-Fi também

Olá @ r004, e bem-vindo ao USE. Geralmente, é uma boa prática modificar suas próprias respostas, em vez de adicionar comentários a elas, se você tiver informações adicionais. Além disso, você pode formatar o texto como código usando backticks.
