乙太網路和 Wifi 問題 Ubuntu 15.10 Lenovo z50

我最近在 Lenovo z50 上安裝了 ubuntu 15.10 和 Windows 10。我已連接 LAN 線並擁有非常好的網路連線（在 Windows 10 中運作良好）。我也配置了代理設定。而且無線網路選項也不存在。

cat /etc/network/interfaces

output:

# interface(s) file used by ifup(8) & ifdown(8)
auto lo
iface lo inet loopback

cat /etc/NetworkManager/NetworkManager.conf

output: 

[main]
plugins=ifupdown,keyfile,ofono
dns=dnsmasq
[ifupdown]
managed=false

cat /etc/resolv.conf

output:

#Dynamic resolv.conf(s) file for glibic resolver(3) generated by     resolvconf(8)
#      DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

ifconfig -a

output:

我無法確定是否需要更多設定或我沒有驅動程式。我搜尋了不同的論壇和博客，但沒有任何效果 Smiley Sad

任何幫助將不勝感激謝謝

使用以下命令檢查您的電腦所需的驅動程式

lspci

就我而言：

sumit@Lenovo-Z50-70:~/Documents/programs$ lspci
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT   Integrated Graphics Controller (rev 0b)
00:03.0 Audio device: Intel Corporation Haswell-ULT HD Audio Controller (rev 0b)
00:14.0 USB controller: Intel Corporation 8 Series USB xHCI HC (rev 04)
00:16.0 Communication controller: Intel Corporation 8 Series HECI #0 (rev 04)
00:1b.0 Audio device: Intel Corporation 8 Series HD Audio Controller (rev 04)
00:1c.0 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 3 (rev e4)
00:1c.3 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 4 (rev e4)
00:1c.4 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 5 (rev e4)
00:1d.0 USB controller: Intel Corporation 8 Series USB EHCI #1 (rev 04)
00:1f.0 ISA bridge: Intel Corporation 8 Series LPC Controller (rev 04)
00:1f.2 SATA controller: Intel Corporation 8 Series SATA Controller 1 [AHCI mode] (rev 04)
00:1f.3 SMBus: Intel Corporation 8 Series SMBus Controller (rev 04)
01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.   RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 10)
02:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)
03:00.0 3D controller: NVIDIA Corporation GM108M [GeForce 840M] (rev ff)

就我而言，這是 Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express 千兆位元乙太網路控制器 (rev 10)。使用以下連結取得 Realtek 驅動程式

http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false

如果您沒有網路連接，請在任何其他系統上執行此操作。下載它並將其複製到系統桌面。提取它。打開終端機。使用命令

cd Desktop/r8168-8.041.01 (go to the extracted folder)
sudo ./autorun.sh

輸入您的密碼。這將安裝驅動程式並建立連接。如果它不起作用，請嘗試重新啟動系統。

對於 wifi，如果您的系統有 Broadcom 無線驅動程序，請參閱此答案：
