[Go] Linux (Debian) install USB wireless card (Tp-link tl-wn725n Rtl8188eu)

1: The desktop home does not want to go any further line. So went to some east bought a USB wireless card. TP's wn725n USB, very small, is almost as large as Logitech's optimal receiver.

2: The driver can identify itself is not expected, since it is USB card, after inserting USB, then LSUSB

Google down, found to be WN725N_V2

Http://wikidevi.com/wiki/TP-LINK_TL-WN725N_v2

Look at the chipset is

Probable Linux driver 8188eu

3: Now that the chipset number has been obtained, first go to the Debian official website to see a wood-driven package, found the Realtek firmware driver

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

But the list of supported is not 8188EU, only 8188ce, 8188CU

It's only going 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. Helpless go to GitHub to stroll, found this

Https://github.com/lwfinger/rtl8188eu

The next step is much better.

Remember to install the build environment and git.

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

If you do not want git, then 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't identify, think for a while ... )

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

#ifconfig-A

This time the system has installed the wireless driver. With the network management software or/etc/network/interfaces inside can be configured.

Note:

But this github update driver, the signal is very poor, after restarting the signal 20%, half a meter distance of only 2 cells. 5 meters is almost gone. And it will decay, after 10 seconds the signal is only 2%. 15 seconds, 0%, no use.

Here a group of the host has uploaded a 8188eu.deb package. After the test found that the signal is very stable, more powerful than under Windows, recommend this

Before installing, you need to uninstall the driver from the GitHub

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

Then go to/lib/modules/' uname-r '/kernel/net/wireless remove Lib8188eu.ko (' uname-r ' This is your kernel version, like mine is 3.2.0.4-AMD64)

Then go to delete the mount, first look at the name Lsmod | More found 8188eu

Then Rmmod 8188eu

This will unload the previous driver.

Then install the 8188eu driver for the new Deb package

Dpkg-i Rtl8188eu-dkms_0+git20130406_all.deb

If the hint is missing dkms, then Ann is a

Then went to/lib/modules/' Uname-r '/updates/dkms, found a more 8188eu.ko

First look at Wlan0 there is no, ifconfig found no should have not hung up

Then Insmod 8188eu.ko.

And then Ifconfig-a found Wlan0.

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