1: 台式機家裡面不想再走線了。 於是去某東買了個USB無線網卡。tp的WN725N USB,非常小, 和羅技的優聯結收器差不多大。
2: 驅動能自己識別是不指望了,既然是usb網卡,插入USB後,那就lsusb
看到新增加了一行Realtek的 ID 0bda:8179

google下了,發現是WN725N_V2
http://wikidevi.com/wiki/TP-LINK_TL-WN725N_v2
看下晶片集是
Probable Linux driver 8188eu
3: 既然拿到了晶片集號, 那就首先去debian官網看有木有驅動的包, 找到了realtek的韌體驅動
http://packages.debian.org/wheezy/firmware-realtek
不過支援的列表裡面並沒有8188eu, 只有8188ce, 8188cu
那就只有去realtek的官網下了, 在
http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false
逛了一圈,還是沒有發現8188eu. 無奈去github上逛逛, 發現了這個
https://github.com/lwfinger/rtl8188eu
接下來就好辦多了。
記得安裝好編譯環境和git
[python] view plaincopy
- #apt-get install gcc linux-headers-`uname -r` make automake git
如果不想git, 那直接download zip file也一樣的
#unzip rtl8188eu-master.zip
#cd rtl818...
#make && make install
接下來
#depmod -a
#modprobe 8188eu
(擼主開始是modprobe rtlwifi發現還是識別不了,想了半天。。。)
接下來就查看下是否有無線網卡了
#ifconfig -a
[python] view plaincopy
- wlan0 Link encap:Ethernet HWaddr 0c:88:77:22:fa:39
- UP BROADCAST MULTICAST MTU:1500 Metric:1

- RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
這個時候系統已經裝好無線驅動了。用網路管理軟體or /etc/network/interfaces 裡面都可以配置。
注:
但是這個github更新的驅動,訊號非常差,重啟後訊號20%,半米的距離只有2格。 5米幾乎就沒有了。而且會衰減下去,10秒後訊號只有2%了。15秒過後就0%了,根本不能用
這裡某群的群主上傳了一個8188eu.deb 的包。 試過後發現訊號非常穩定, 比windows下的還要強, 推薦這個
地址在csdn這裡:(不要積分)

安裝前需要卸載掉之前安的這個github上下的驅動,
先去/lib/firmware/rtlwifi/ 刪除掉rtl8188eufw.bin
然後去/lib/modules/`uname -r`/kernel/net/wireless 刪除掉lib8188eu.ko (`uname -r` 這個是你的核心版本,比如我的是3.2.0.4-amd64)
然後去刪除掉掛載,先查看名字 lsmod | more 找到8188eu
然後rmmod 8188eu
這樣就把之前的驅動給卸載掉了
然後安裝新的deb包的8188eu驅動
dpkg -i rtl8188eu-dkms_0+git20130406_all.deb
如果提示缺少dkms,那就安一個
apt-get install dkms
[python] view plaincopy

然後去/lib/modules/`uname -r`/updates/dkms ,發現多了一個8188eu.ko
先看看wlan0 有沒有, ifconfig 發現沒有 應該是還沒掛上
執行depmod -a
然後insmod 8188eu.ko
再ifconfig -a 發現有了wlan0
把網路管理切換過去,發現訊號很滿! 自此,安裝完了8188eu的驅動.
