linux中使用broadcom型号卡上网
确认下网卡型号：
sanshang@ubuntu:~$lspci|grep-inetwork
06:00.0Networkcontroller:BroadcomCorporationBCM4312802.11b/g(rev01)
1、进入http://www.broadcom.com/support/802.11/linux_sta.php下载驱动，我选择的是32-bitdriver；
新建目录，解压文件
#mkdirhybrid_wl
#cdhybrid_wl
#tarxzf/home/sanshang/Downloads/hybrid-portsrc-x86_32-v5.10.91.9.3.tar.gz
2.BuildthedriverasaLinuxloadablekernelmodule(LKM):
#makeclean(optional)
#make
Whenthebuildcompletes,itwillproduceawl.kofileinthetoplevel

Ifyouwerealreadyrunningapreviousversionofwl,you'llwanttoprovidea
cleantransitionfromtheolderdriver.(Thepathtopreviousdriverisusually
/lib/modules/<kernel-version>/kernel/net/wireless)
#rmmodwl
#mv<path-to-prev-driver>/wl.ko<path-to-prev-driver>/wl.ko.orig
#cpwl.ko<path-to-prev-driver>/wl.ko
#depmod
#modprobewl
Otherwise,ifyouhavenotpreviouslyinstalledawldriverdothis:
如果没有，就直接执行下面的命令：
#modprobelib80211
#insmodwl.ko
wl.koisnowoperational.ItmaytakeseveralsecondsfortheNetworkManager
tonoticeanewnetworkdriverhasbeeninstalledandshowthesurrounding
wirelessnetworks.
按照readme中的步骤就可以安装完成,但是每次系统启动的时候不会自动加载,那么就需要将wl.ko拷贝到:
/lib/modules/2.6.31-14-generic/kernel/net/wireless/
目录,然后在/etc/rc.local加入:
modprobe-rssb
modprobewl
or
modprobelib80211
insmod/lib/modules/2.6.31-14-generic/kernel/net/wireless/wl.ko
这样就可以了
激活网卡驱动

解决QQ掉线
sudogedit/usr/bin/qq
此为打开编辑命令，打开后显示：
#!/bin/sh
cd/usr/share/tencent/qq/
在中间加入一句即可
#!/bin/sh
exportGDK_NATIVE_WINDOWS=true
cd/usr/share/tencent/qq/
升级后启动不了的解决办法：
grub>ls
grub>ls(hd0,7)/#找出WUBI安装的盘，里面有ubuntu/这个目录。
grub>insmodntfs#加载ntfs模块，因为WUBI将ubuntu安装到了我分的ntfs盘上
grub>setroot=(hd0,7)#这里(hd0,7)就是我找到的ubuntu安装的分区
grub>ls$Boot#找到我们BOOT分区的UUID，下一步要用到，我这里显示出来的是2250018e50016a3d
grub>search--no-floppy--fs-uuid--setf2250018e50016a3d#这里的UUID就是上一定找出来的那个
grub>loopbackloop0/ubuntu/disks/root.disk#设loop0,WUBI装ubuntu安装成了一个root.disk文件
grub>setroot=(loop0)#重设root
grub>linux/boot/vmlinuzxxxxxxxxx(tab补全即可,有2个，14和19，补全14的那个，注意文件名要完整)root=/dev/sda7loop=/ubuntu/disks/root.diskroquietsplash#加载内核，sda7对应就是(hd0,7)
grub>initrd/boot/initrd.imgxxxxxxxxxxxx(tab补全即可，同样选14的那个)#不用说大家都知道
gurb>boot
ENTER就可以启动了。进入熟悉的系统，打开终端
代码:
首先切换到root用户，sudo-s-H
#update-grub2
#reboot
