Eu instalei o Ubuntu no meu laptop pessoal e conectei a um wifi de hotel que eu tinha usado anteriormente com o Windows no mesmo PC. Essa rede é um wifi de hotel padrão onde você precisa colocar suas credenciais como hóspede para obter acesso, mas ele se conectou diretamente sem nenhum prompt, como se tivesse ignorado o prompt do roteador.
Minha pergunta é como? Ele detectou o endereço MAC do meu laptop e então simplesmente assumiu que era eu?
O Archer T4u suporta USB 3 de acordo com a documentação oficial, mas quando eu o conecto a uma porta USB 3, ele é detectado como um dispositivo USB 2 (conforme a saída lsusb). Eu tentei isso no meu PC Ubuntu e no meu laptop executando o Fedora 40, ambos com portas USB 3.1 mais novas. O dispositivo funciona sem instalar nenhum driver.
Quero que meu laptop com Ubuntu esteja na lista branca de um hotspot WiFi Android. Fazendo hostnamectlretornos, entre outras informações, um Static hostname, um Icon name, um Machine IDe um Boot ID. Qual destes é o correto?
Eu obtive o endereço MAC da wlan0interface fazendo isso ip addrno terminal e adicionei, junto com o Static hostname, à lista branca, mas a conexão falha. A intensidade do sinal é muito boa e a senha WPA2 está correta.
PS.: Em uma máquina com Windows 10, você obtém o nome correspondente hostnamena linha de comando ou pesquisando em Settings > System > About"Nome do dispositivo".
novo usuário de Linux aqui. Não consigo encontrar wifi no laptop Dell XPS 13 9343 conectado à internet via tethering USB. Placa sem fio - Broadcom BCM4352 802.11ac Dual Band (14e4:43b1) rev 03. Tentei instalar bcmwl-kernel-source e firmware-b43-installer, mas estou recebendo o erro unable to locate package para ambos os comandos.
Por favor ajude!
O Wifi do meu PC parou de funcionar recentemente, provavelmente depois de uma atualização do kernel ou algo assim. O Wifi se conecta ao SSID e a porta recebe um endereço IP. No entanto, não consigo fazer ping em nada além do próprio host. Tentei reiniciar, reconectar, reiniciar o roteador Wifi, desabilitar o GUFW, etc., mas nada funcionou. Todo o resto está funcionando bem na LAN.
Tentei adicionar o parâmetro de inicialização do Grub abaixo, mas não ajudou:
pcie_aspm=off
Alterei o parâmetro abaixo para desabilitar o modo de economia de energia, mas isso não ajudou em nada - /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf:
wifi.powersave = 3 ==> 2
Alterei o modo de economia de energia no Gerenciamento de energia para Equilibrado, o problema ainda persistia.
Dongle Wifi éTP-Link Archer T3U [Realtek RTL8812BU]
Suspeito de um bug no kernel ou firmware ou então problemas de hardware. Por favor, me oriente para descobrir o problema e ajude a resolver, se possível.
Abaixo está a saída do comando DMESG e do script Wireless-info:
No passado, as senhas de WiFi podiam ser encontradas em arquivos /etc/NetworkManager/system-connections/. Com o novo Ubuntu 24.04 Noble Numbat, essa pasta está vazia (mesmo que eu esteja usando WiFi doméstico agora para postar esta pergunta).
Então a questão é: onde as senhas WiFi são armazenadas agora?
PS: Também tenho conexões VPN Wireguard ativas feitas por meio da NetworkManagerGUI. A /etc/NetworkManager/system-connections/VPNpasta também está vazia.
Estou executando o Ubuntu 22.04.4 (dual boot com win11) em um labtop com wifi7 da Intel.
Tudo estava indo bem até que eu confiei cegamente em uma atualização de software do sistema da atualização de software do Ubuntu. Logo após a atualização o computador ainda estava com conexão WiFi estável, na qual instalei o idioma chinês através da configuração de idioma e região e fiz uma reunião de zoom. Mas depois que o computador for reiniciado, o WiFi só ficará conectado por um minuto, depois disso não funcionará e depois de um tempo poderá funcionar.
Se eu clicar em configuração de WiFi, o NetworkManager está desligado. Então tentei o seguinte:
A seguir está um dump da saída de dmesg -wquando a rede passa de funcionando para não funcionando.

Obrigado antecipadamente!
PS: Acho que o hardware WiFi está funcionando porque está funcionando bem com o win11
Novato, instalou recentemente o sistema operacional Ubuntu Server no Raspberry Pi 4. Isso mostra que as redes não são gerenciadas, também pode ser a razão pela qual o ROS na máquina de desenvolvimento não consegue se comunicar com o ROS no Raspberry Pi quando experimentei a demonstração do locutor e do ouvinte.
Instalei o Ubuntu 22.04.4 mas a opção wifi não está disponível, Laptop: Asus Vivobook 16X. https://paste.ubuntu.com/p/zsmVFbhPVn/

########## wireless info END ############
Depois de uma atualização recente, percebendo que o Wi-Fi é desconectado aleatoriamente, as velocidades variam de 0,1 Mbps a 100 Mbps em alguns segundos, podendo durar alguns segundos ou algumas horas, o que não é previsível. Estou tentando registrar um relatório de bug usando ubuntu-bug, mas não sei qual pacote está com defeito.
Estas podem ser algumas informações relevantes, mas olhei os módulos e não vi nada parecido rtw_8821ce, existem rtw88_*módulos que podem ser relevantes, mas, de qualquer forma, não consigo mapeá-los para nenhum pacote, pelo que sei.

Esta foi a melhor referência que encontrei: WiFi desconecta com frequência e aleatoriamente, driver rtw_8821ce , mas mesmo estando na seção "Newbie Corner", não consigo acompanhar o que eles estão fazendo. Como "Você tentou se conectar apenas com wpa_supplicant (e um cliente DHCP, se necessário)?" está muito acima do meu nível de habilidade.
De qualquer forma, gostaria de pelo menos preencher um relatório de bug se alguém puder ajudar a identificar o pacote relevante.
Conforme solicitado, esta é a saída relevante de iwconfig, acabei de reiniciar, pois isso às vezes ajuda um pouco, então as estatísticas podem não ser representativas:
