Ubuntu 13.10 上无线无法正常工作

我刚刚安装了 Ubuntu 13.10,但是无线无法工作并且没有显示无线网络:

命令:iwconfig
输出:

eth0 no wireless extensions.

eth1 IEEE 802.11abg EEID:off/any
     Mode:Managed Access Point: Not-Associated Tx-Power-19 dBm
     Retry long limit:7 RTS thr:off Fragment thr:off
     Power Management:off

lo   no wireless extensions.

lspci -nn | grep 0280

输出:

02:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11bgn Wireless
Network Adapter [14e4:4727] (rev 01)

命令 lsmod | grep -e b43 -e brcm -e wl
输出:

wl          4207474         0
lib802011   14352           2 wl,lib80211_crypt_tkit
cfg80211    479757          1 wl

以下命令:
sudo -i
apt-get purge bcmwl-kernel-source
echo "blacklist b43" >> /etc/modprobe.d/blacklist.conf
exit

输出为:

youssef@YoussefSiblini:~$ sudo -i

lsmod | grep -e brcm -e wl 和 rfkill 的输出列出所有

请打开终端并执行:

sudo -i
apt-get purge bcmwl-kernel-source
echo "blacklist b43" >>  /etc/modprobe.d/blacklist.conf
exit

重新启动并让我们获得您的报告。

如果您尝试执行以下操作,您的以太网是否会启动:

sudo ifconfig eth0 down
sudo ifconfig eth0 up
ifconfig

ethtool 安装了吗?

sudo ethtool -s eth0 autoneg off speed 100

如果以太网现在正常工作:

sudo apt-get update
sudo apt-get purge bcmwl-kernel-source

如果仍然无法连接以太网,请将 wl 列入黑名单:

sudo -i
echo "blacklist wl" >>  /etc/modprobe.d/blacklist.conf
rm /etc/modprobe.d/blacklist-bcm43.conf
modprobe brcmsmac
exit

重新启动并让我们听到您的结果。
