成功连接 wifi 后，执行下面命令 把结果全部复制贴上来

代码： 全选

uname -a
lspci -knn
sudo lshw -C net
sudo ifconfig -a
sudo iwconfig
sudo cat /etc/resolv.conf
sudo route -nv
sudo nmcli dev show

断开无线，连接有线，执行

代码： 全选

sudo apt-get install pastebinit
cd
wget -O wireless-info http://git.oschina.net/pastebin/wireless-info/raw/master/wireless-info
bash wireless-info
sudo cat /var/log/syslog | pastebinit

稍等片刻，将回应的两个网址 (http://paste.ubuntu.com/87987888) 贴上来

这个 回应的两个网址 我不太理解，请问是什么意思？

执行后会返回两个网址
类似这样

不过不必了，上面的信息已经足够了

刚刚是命令没执行完所以没看到，上面两个链接应该就是了

03:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] (rev 01)
Subsystem: Broadcom Corporation Device [14e4:0608]
Kernel driver in use: bcma-pci-bridge
...driver=brcmsmac...

Boardcom 网卡有三款驱动: b43, brcm80211, wl
对于 BCM4313：
1. b43 - 不支持 参见 https://wireless.wiki.kernel.org/en/users/drivers/b43
2. brcm80211(brcmsmac) - 有限的支持 参见 https://wireless.wiki.kernel.org/en/use ... /brcm80211
3. wl - 支持，但不稳定的情况居多

目前作用中驱动 brcm80211(brcmsmac) 但是：

Please note: at least BCM4313 is not fully supported. Some models appears to work (users reported success), but some don't, and there's no indication that this is going to change. For example: http://marc.info/?t=138817851800006&r=1&w=2

尝试安装私有驱动 wl
1.

代码： 全选

sudo apt-get install build-essential linux-headers-3.13.0-53-generic

2.
从 “附加驱动” 中安装无线网卡的附加驱动
3.
编辑或创建 /etc/modprobe.d/wl.conf 添加以下内容

代码： 全选

blacklist b43
blacklist b43legacy
blacklist b44
blacklist bcma
blacklist brcm80211
blacklist brcmsmac
blacklist ssb

4.
重新启动计算机

[LeChauvet]

按照你的指导操作了但是网络设置中现在找不到无线连接选项了

[LeChauvet]

已经好了，刚刚没注意到第二步，谢谢您的慷慨帮助

[vickycq]

已经好了，刚刚没注意到第二步，谢谢您的慷慨帮助

恭喜

但是网络设置中现在找不到无线连接选项了

可能私有驱动 wl 没安装成功，b43 和 brcmsmac 又被加入黑名单，导致看不到无线界面。
用 lsmod | grep wl 确认 wl 模块载入情况，若无输出说明未载入

在“附加驱动”中取消无线网卡私有驱动
移除之前创建的 /etc/modprobe.d/wl.conf
重新启动计算机 - 此时应该恢复到主楼的状态
连接有线

代码： 全选

sudo apt-get install build-essential linux-headers-3.13.0-53-generic
sudo apt-get install broadcom-sta-dkms

安装过程中注意有无错误，若有错误，将输出复制贴上来
重新启动计算机[/s]

大神，我也遇到同样的问题，有线可以连，可以上网，但无线能连得上，不能上网。之前可以的，我换了一个小米路由器就不行了，下面是根据上面的提示得到的两个网址，帮忙看一下，感激不尽
