Linux (Debian) install USB wireless network card (Tp-link tl-wn725n Rtl8188eu) __linux

1: The desktop home does not want to walk the line again. So went to a certain east bought a USB wireless network card. TP's wn725n USB, very small, is about the size of Logitech's superior receiver.

2: Drive can identify itself is not expected, since it is a USB card, insert USB, then LSUSB

Google, and found it was wn725n_v2.

Look at the chipset is

Probable Linux driver 8188eu

3: Now that you have the chipset number, first go to the Debian official website to see the wood-driven package, found the Realtek firmware driver

Http://packages.debian.org/wheezy/firmware-realtek

But there's no 8188eu in the support list, only 8188ce, 8188CU

Then only go to Realtek's official website, in

Http://www.realtek.com/downloads/downloadsView.aspx? Langid=1&pnid=21&pfid=48&level=5&conn=4&downtypeid=3&getdown=false

Stroll around, still did not find 8188eu. But I went to GitHub and found this.

Https://github.com/lwfinger/rtl8188eu

The next step is much better.

Remember to install the compilation environment and Git.

#apt-get Install gcc linux-headers-' uname-r ' Make automake git

If you don't want to git, the direct download zip file is the same

#unzip Rtl8188eu-master.zip

#cd rtl818 ...

#make && make Install

Next

#depmod-A

#modprobe 8188eu

(The main start is modprobe Rtlwifi found or can not recognize, think for a long time ...) )

Next, check to see if you have a wireless card.

#ifconfig-A

Wlan0     Link encap:ethernet  hwaddr 0c:88:77:22:fa:39 up

This time the system has been installed wireless drive. Use network management software or/etc/network/interfaces inside all can configure.

Note:

But this github updated drive, the signal is very poor, reboot after the signal 20%, half a meter distance of only 2 cells. 5 meters is almost gone. And will decay, 10 seconds after the signal is only 2%. 15 seconds later, 0%, it's not going to work.

Here a group of owners uploaded a 8188eu.deb package. After the test found the signal is very stable, more than under the windows of the stronger, recommend this

Before installing, you need to uninstall this GitHub up and down drive,

First go to/lib/firmware/rtlwifi/delete Rtl8188eufw.bin

Then go to/lib/modules/' uname-r '/kernel/net/wireless delete lib8188eu.ko (' uname-r ' This is your kernel version, like mine is 3.2.0.4-AMD64)

Then go to remove the mount, first check the name Lsmod | More Find 8188eu

And then Rmmod 8188eu.

So we unloaded the previous driver.

Then install the new Deb Pack's 8188eu drive

Dpkg-i Rtl8188eu-dkms_0+git20130406_all.deb

If the hint lacks dkms, then an

Then go to/lib/modules/' uname-r '/updates/dkms and find one more 8188eu.ko

Let's see if Wlan0 is there, Ifconfig found out it's not on the hook yet.

Execute depmod-a

and then Insmod 8188eu.ko

And then Ifconfig-a found Wlan0.

Switch the network management over and find the signal is full. Since then, the 8188eu driver has been installed.
