yoga 11s 安装了ubuntu kylin 14.04 版本后无法链接网络，现在用的是USB网卡上网，请求大神帮忙，着急！

今天问题已经解决，网络可以链接，蓝牙依然不能用，wifi解决方法如下：
1：wifi 硬件驱动下载附件：以提供
2：打开终端，进入附件目录
cd **[驱动名称]
make
sudo make install
sudo modprobe 8723au

把下面指令 複製 貼進終端機 執行
1. sudo lshw -numeric -class network # 請指名 哪個網卡是 USB 網卡
2. sudo ifconfig -a
3. sudo route -nv
4. sudo dhclient -v
把結果直接複製 貼上來

这个上面能获取到的192.168.2.103的网卡就是USB的磊科无线网卡，笔记本自身的无线并没有驱动

笔记本自身的无线并没有驱动

sudo lshw -numeric -class network
沒有偵測到硬件

sudo lshw -numeric -class network
description: Wireless interface
configuration: ... driver=rtl8192cu...

沒有偵測到 [xxxx:yyyy] 例如 [13F0:1023]
所以無法判斷 rtl8192cu 驅動是否是最合適的

從終端機
1. sudo lspci -nnvv
兩個 n 兩個 v
2. 如果你的無線網卡 是 USB 額外增加
sudo lsusb -v
3. 把結果 直接複製 貼上
http://paste.ubuntu.com
再把網址貼上來
4. 終端機 可能超過顯示 512 列的限制 參考
viewtopic.php?f=48&t=462403&p=3096730#p3096730
取消 512 列的限制
5. 查一下 硬體使用說明書 看看 正確的 無線網卡 品牌與型號

型号没有问题，但是现在蓝牙模块并没有驱动，电脑在重新启动以后，wifi驱动也会丢失，需要重新安装，请问，这个怎么解决，那个firmware 是干嘛用的，需要安装吗？

电脑在重新启动以后，wifi驱动也会丢失，需要重新安装

如果正常安裝 應該不會丟失 如果會丟失 表示安裝不正常

firmware 是干嘛用的，需要安装吗？

這個型號的無線網卡 需要額外安裝 firmware
configuration: broadcast=yes driver=rtl8192cu driverversion=3.13.0-24-generic firmware=N/A
安裝以後 會顯示在 N/A 位置

非常感谢您的回复，filmware我这里不知道该怎么下装，还有上次提到的蓝牙问题，您没有给出解答方案。

firmware 是干嘛用的，

http://thread.gmane.org/gmane.linux.network/301126
> This firmware is for a driver that will soon be submitted to the kernel.
> It occurs as data statements in Realtek driver rtl8723A_WiFi_linux_v4.1.3_6044.20121224.

filmware我这里不知道该怎么下装

直接安裝 linux-firmware 套件看看
1. linux-firmware 1.122 版
https://launchpad.net/ubuntu/+source/li ... ware/1.122
rtlwifi: Add firmware for r8723au
1-1. 目前 Ubuntu 14.04 的 linux-firmware 是 1.127.5
安裝好後 重新開機 看看

1. 如果你是下載
https://launchpad.net/ubuntu/+source/li ... re/1.127.5
“linux-firmware” 1.127.5 source package in Ubuntu
需要經過編譯 參見
https://help.ubuntu.com/community/CompilingEasyHowTo

2. 如果你是下載
https://launchpad.net/ubuntu/trusty/+pa ... x-firmware
Binary package “linux-firmware” in ubuntu trusty
應該就可以直接安裝 不必再經過編譯

3. 參閱
https://help.ubuntu.com/community/Insta ... _Binary.3F

还有上次提到的蓝牙问题

此芯片还有bluetooth功能，不过驱动尚未准备好，Larry W. Finger也打算与realtek共同努力解决对蓝牙的支持
# ifconfig
就可以看到wlan设备了，信号还不错哈。
蓝牙还不行。

RTL8723AU wifi驱动终于要进3.15内核了
貌似Bluetooth仍然用不了。
