15.10 can't connect to wired connection

I was previously toying with using 15.04 on my office computer, and it worked умер out of the box. This week I decided to give it another shot with 15.10 (using кусок веревки 2, then the past 3 days' daily builds). I understand these пахал not будьте перечитан versions, but I doubt that in the next 12 hours, developers will be focused on this specific issue versus обитайте release-related matters.

Anyways, when I boot either the installer or live интерфейс, I cannot connect to my network путь my wired connection. The wired connection worked find in 15.04, and works умер when I flip back to Windows. гve tried running lshw-c network, followed by ifconfig, and it is detecting the run-of-the-mill Realtek onboard adapter (model, MAC, и т.д.), and actively trying to get an IP. In the GUI, the network-менеджер indicator also шоу that it's trying to get an IP, but it periodically gives up.

If I manually set an IP with ifconfig, гm still unable to ping any other devices on the network.

Any suggestions?

Edit: NIC is в Realtek RTL8111E on an Asrock B75M-DGS R2.0 board

У нас есть подобная проблема о 2 машинах после 15,10 установок (не, обновляют). IP-адрес succefully полученный, работы локальной сети хорошо, но сбои интернет-соединения (проверяют с помощью ping-запросов connamd, показал 100%-ю потерю при проверке с помощью ping-запросов именем хоста или IP). Эта ссылка не решает мою проблему completly (я не вижу соединения в сетевом-manaher GUI), но теперь у меня есть доступ к СЕТИ.

, что я сделал: Отредактируйте файл “/etc/network/interfaces” и изменение, это похоже на это: 

#The loopback network interface - this was default string
auto lo
iface lo inet loopback

#The primary network interface - I've add this
iface enp2s0 inet static 
address 169.254.29.64

Это должно помочь. Подключите к Интернету альтернативный путь и выполнение в терминале: 

sudo apt-get install r8168-dkms
sudo modprobe -r r8169
sudo modprobe r8168

, Если Вы не можете соединить альтернативный путь, затем необходимо будет загрузить r8168-dkms и dkms пакеты отдельно.
