升级到17.04后无法连接无线网络

[bxyun]

从16.10在线升级到17.04后，找不到无线网卡，型号是博通4352双频无线网卡，网络菜单下也没有启用无线的按钮，但是在附加驱动里面显示驱动已经安装。

重新启动计算机后，立刻执行以下指令将结果全部复制贴上来

代码： 全选

sudo dmesg | grep wl
uname -a
lspci -knn | grep -iA2 net
sudo lshw -C net
sudo rfkill list all
dpkg -l | grep 'broadcom\|bcmwl'
find /lib/modules/ | grep wl.ko

已经解决了，想办法连上有线网络，卸载后重新安装驱动就能连上了，谢谢

你好，我的个人电脑从16.10升级到17.04之后，所有的网络均无法使用，包括有线网，无线网，以及我用手机共享的网络。无线网还能搜索到wifi，但是所有的都是无法连接。因为我的home没有单独分区，所以我不想重装系统。
双系统Windows有线无线都可以用。下面是我的指令

zh@zh-pc:~$ sudo dmesg | grep wl

无线网 无线网还能搜索到wifi，但是所有的都是无法连接。
configuration: broadcast=yes driver=rt2800usb driverversion=4.10.0-19-
wlx44334c30b42b: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500

解决无线网无法使用问题
禁用NetworkManager的mac地址欺骗。

编辑 /etc/NetworkManager/NetworkManager.conf 并添加

代码： 全选

[device]
wifi.scan-rand-mac-address=no 

并运行

`systemctl restart NetworkManager`

它就可能开始为你工作。

所有的网络均无法使用，包括有线网
Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168]
configuration: autonegotiation=on broadcast=yes driver=r8169

解决有线网无法使用问题
猜测原因为：r8169 驱动用于 PCI ID 为 10ec:8168 的网卡时出现问题。您可以通过更换驱动为 r8168 来尝试解决此问题。先解决无线网无法使用问题，连接无线网后，执行 sudo apt install r8168-dkms，重新启动计算机。
