两三天前，我已将 kernel 更新到3.2.0-29-generickernel 3.2.0-27-generic。从那时起，我的无线就无法工作了……之前它可以正常工作。
它一直要求我输入密码。有时可以连接，但速度非常非常慢……最多不超过 2 到 4kb。

解决了
问题出在网络管理器上
gksu gedit /etc/wpa_supplicant.conf
在文件中添加以下内容WPA2
ctrl_interface=/var/run/wpa_supplicant
network={
ssid="ESSID_IN_QUOTES"
psk="ASCII PSK Password in Quotes"
key_mgmt=WPA-PSK
proto=RSN WPA
pairwise=CCMP TKIP
group=CCMP TKIP
}
我的示例：ssid="ABCD" 和密码是 = psk="abc12345"
然后移除网络管理器-gnome
apt-get purge network-manager-gnome
设置启动时连接的无线接口
gksu gedit /etc/rc.local
添加以下行
ifconfig eth0 down
ifconfig wlan0 down
dhclient -r wlan0
iwconfig wlan0 essid "A-B-C-D"
iwconfig wlan0 mode Managed
ifconfig wlan0 up
dhclient wlan0
然后重新启动网络..我重新启动了
