Boa noite!

Estou com os seguintes problemas de conexão no Lubuntu:

Instalei a distro no meu PC Desktop e, como não consegui conectar ele em rede via cabo RJ45, comprei um adaptador willeress USB.

Acontece que ele até reconhece as redes disponíveis, reconhece a minha, pede senha e tudo. Porém, não acessa nada na internet.

Tentei fazer conexão via Vinculo USB pelo celular, mas acontece o mesmo problema. Segundo algumas pesquisas que realizei na internet, pode ser problemas com DNS, mas como sou "novato" nesse sistema, não faço nem ideia de como configurar?

Será que alguém pode me ajudar? Obrigado!! :)

1- Coloca o adaptador willeress USB na porta usb e espera 20 s.

2- Qual a saída dos comandos?

uname -a

lsusb

lsusb -v

dmesg | grep firmware

dmesg | grep failed

cat /etc/group

Descobri o problema em parte.

Ao executar o primeiro comando "uname -a", verifiquei que o "ano" da data estava errado. Arrumei isso e consegui fazer a conexão com vinculo USB usando o celular. Internet funcionando! hehe

Vou testar o adaptador agora e posto os resultados.

cleiton@cleiton-945GCM-S2C:~$ dmesg | grep firmware

cleiton@cleiton-945GCM-S2C:~$ dmesg ! grep failed



Usage:

 dmesg [options]



Display or control the kernel ring buffer.



Options:

 -C, --clear                 clear the kernel ring buffer

 -c, --read-clear            read and clear all messages

 -D, --console-off           disable printing messages to console

 -E, --console-on            enable printing messages to console

 -F, --file <file>           use the file instead of the kernel log buffer

 -f, --facility <list>       restrict output to defined facilities

 -H, --human                 human readable output

 -k, --kernel                display kernel messages

 -L, --color[=<when>]        colorize messages (auto, always or never)

                               colors are enabled by default

 -l, --level <list>          restrict output to defined levels

 -n, --console-level <level> set level of messages printed to console

 -P, --nopager               do not pipe output into a pager

 -r, --raw                   print the raw message buffer

 -S, --syslog                force to use syslog(2) rather than /dev/kmsg

 -s, --buffer-size <size>    buffer size to query the kernel r

 ing buffer

 -u, --userspace             display userspace messages

 -w, --follow                wait for new messages

 -x, --decode                decode facility and level to readable string

 -d, --show-delta            show time delta between printed messages

 -e, --reltime               show local time and time delta in readable format

 -T, --ctime                 show human-readable timestamp (may be inaccurate!)

 -t, --notime                don't show any timestamp with messages

     --time-format <format>  show timestamp using the given format:

                               [delta|reltime|ctime|notime|iso]

Suspending/resume will make ctime and iso timestamps inaccurate.



 -h, --help     display this help and exit

 -V, --version  output version information and exit



Supported log facilities:

    kern - kernel messages

    user - random user-level messages

    mail - mail system

  daemon - system daemons

    auth - security/authorization messages

  syslog - messages generated internally by syslogd

     lpr - line printer subsystem

    news - network news subsystem



Supported log levels (priorities):

   emerg - system is unusable

   alert - action must be taken immediately

    crit - critical conditions

     err - error conditions

    warn - warning conditions

  notice - normal but significant condition

    info - informational

   debug - debug-level messages





For more details see dmesg(1).

Tem que usar o usuário root nos comandos conforme o tópico 2 posta a saída de novo.

Faltou esses comando no tópico 2
