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:

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:

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。
