linux（debian）安装USB⽆线⽹卡（tp-linkTL-
WN725Nrtl8188eu）
1: 台式机家⾥⾯不想再⾛线了。于是去某东买了个USB⽆线⽹卡。tp的WN725N USB,⾮常⼩, 和罗技的优联接收器差不多⼤。
2: 驱动能⾃⼰识别是不指望了，既然是usb⽹卡，插⼊USB后，那就lsusb
看到新增加了⼀⾏Realtek的 ID 0bda:8179

google下了，发现是WN725N_V2
看下芯⽚组是
Probable Linux driver 8188eu
3: 既然拿到了芯⽚组号，那就⾸先去debian官⽹看有⽊有驱动的包, 到了realtek的固件驱动
不过⽀持的列表⾥⾯并没有8188eu，只有8188ce, 8188cu
那就只有去realtek的官⽹下了, 在
逛了⼀圈，还是没有发现8188eu. ⽆奈去github上逛逛，发现了这个
接下来就好办多了。
记得安装好编译环境和git
[python]
1. #apt-get install gcc linux-headers-`uname -r` make automake git
如果不想git，那直接download zip file也⼀样的
#unzip rtl8188eu-master.zip
#
#make && make install
接下来
#depmod -a
#modprobe 8188eu
(撸主开始是modprobe rtlwifi发现还是识别不了，想了半天。。。)
接下来就查看下是否有⽆线⽹卡了
#ifconfig -a
[python]
1. wlan0 Link encap:Ethernet HWaddr 0c:88:77:22:fa:39
2. UP BROADCAST MULTICAST MTU:1500 Metric:1
3. RX packets:0 errors:0 dropped:0 overruns:0 frame:0
4. TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
5. collisions:0 txqueuelen:1000
6. RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
这个时候系统已经装好⽆线驱动了。⽤⽹络管理软件or /etc/network/interfaces ⾥⾯都可以配置。
注:
但是这个github更新的驱动，信号⾮常差，重启后信号20%，半⽶的距离只有2格。 5⽶⼏乎就没有了。⽽且会衰减下去，10秒后信号只有2%了。15秒过后就0%了，根本不能⽤
这⾥某的主上传了⼀个8188eu.deb 的包。试过后发现信号⾮常稳定，⽐windows下的还要强，推荐这个
地址在csdn这⾥：(不要积分)
安装前需要卸载掉之前安的这个github上下的驱动，
先去/lib/firmware/rtlwifi/ 删除掉rtl8188eufw.bin
然后去/lib/modules/`uname -r`/kernel/net/wireless 删除掉lib8188eu.ko （`uname -r` 这个是你的内核
版本，⽐如我的是3.2.0.4-amd64）然后去删除掉挂载，先查看名字 lsmod | more 到8188eu
然后rmmod 8188eu
这样就把之前的驱动给卸载掉了
然后安装新的deb包的8188eu驱动
dpkg -i rtl8188eu-dkms_0+git20130406_all.deb
如果提⽰缺少dkms，那就安⼀个
apt-get install dkms
[python]
1. dpkg -i rtl8188eu-dkms_0+git20130406_all.deb
2. Selecting previously unselected package rtl8188eu-dkms.
3. (Reading database ... 172290 files and directories currently installed.)

46. DKMS: install completed.
然后去/lib/modules/`uname -r`/updates/dkms ，发现多了⼀个8188eu.ko
先看看wlan0 有没有， ifconfig 发现没有应该是还没挂上
执⾏depmod -a
然后insmod 8188eu.ko
再ifconfig -a 发现有了wlan0
把⽹络管理切换过去，发现信号很满！⾃此，安装完了8188eu的驱动.
