Беспроводное подключение, но без подключения к Интернету (Ubuntu 12.04)

7

Я использую одну и ту же сеть в течение 2 дней, и все было нормально. Однако сегодня, хотя он показывает, что я подключен к сети, у меня нет подключения к Интернету. Если я использую Ethernet-кабель вместо беспроводной, я все еще могу подключиться к Интернету. Также мои друзья могут подключиться к беспроводной сети, и они могут подключиться к Интернету. Я ничего не обновлял и не устанавливал со вчерашнего дня. Поэтому я не знаю, почему это происходит. Вот несколько сведений о моем соединении:

Я буду благодарен за любую помощь.

Вы также можете проверить / var / log / syslog на наличие ошибок с помощью редактора.

Если вы подключены к DHCP-серверу (в основном шлюзу), попробуйте вручную получить аренду ip, используя dhclient eth1 .

Попробуйте выполнить проверку на ваш шлюз, чтобы проверить, подключены ли вы к нему.

У меня возникла такая же проблема, но я исправил ее, изменив настройки маршрутизатора. Я переключил выбор канала с AUTO на 1. По-видимому, моя проблема возникла, когда автоматически был выбран Channel > 11. На самом деле моя проблема не возникала непрерывно.

Кажется, у вас нет IP-адреса.

  IPv4 Settings:
Address:         0.0.0.0 <----- NO IP
Prefix:          24 (255.255.255.0)
Gateway:         192.168.1.1

DNS:             192.168.1.1

Проверить IP-адрес с помощью

 ifconfig

и маршрут с помощью

 route -n

Это может быть несколько вещей, но я думаю, что брандмауэр блокирует весь трафик:

  1. Ошибка аппаратного обеспечения диска, например ошибки ввода-вывода, может привести к отключению сети, поскольку она не может хранить данные из браузера.

  2. Блокирующий трафик брандмауэра должен иметь правило разрешать tcp 25,53,80,110,443, а также разрешать udp 53.

  3. Если у вас несколько программ брандмауэров, работающих одновременно, что также может стать проблемой, например ufw и gufw, лучше использовать только gufw ...

Мне пришлось делать:

ifdown eth0

, чтобы заставить мой wlan0 работать на самом деле. У меня уже была арендная плата и т. Д. Я бегу 12,04 кстати.

Вы проверили свою IP-конфигурацию?

 ifconfig eth1

и таблица маршрутизации

route -n

Просто чтобы проверить, в чем проблема.

Я пробовал это, и он работал

sudo modprobe -rv wl
sudo apt-get remove --purge bcmwl-kernel-source
sudo modprobe -v brcmsmac
