HowTo using TP-Link WN725 on Raspberry Pi running Pidora

2016-03-30T20:15:31Z

WikiRAdmin:

<div class="noautonum">__TOC__</div>

=Introduction=

This guide is about using the TP-Link TL-WN725N USB WiFi Dongle on a Raspberry Pi and Pidora. After spending more than 1 day searching on Google and trying all possible things, I succeeded making it work.

I am using a minimal Pidora installation with no NetworkManager. Since it was challenging enough I have decided to put it all together here.

If this page helps you, please link to it (e.g. from discussion groups) or put a nice comment on the discussion page :). This page is intended for people with Linux skills (Fedora preferably). If you are a beginner, you can follow the steps, but you need to google a little bit about what is the meaning of each command.

The TL-WN725N USB WiFi Dongle requires enough current to make the Pi reboot if you insert or remove it when working! Please shutdown your system before inserting or removing the adapter.

=Step 1: Firmware=

If you get something like "Direct firmware load for rtlwifi/rtl8188eufw.bin failed with error -2" when booting with the Wifi Dongle installed or Typing lsusb is not displaying the device, then you are not having the firmware installed. You have to Download and install the firmware:
* download the firmware to a subdirectory rtl8188eu/
* copy the firmware (file rtl8188eufw.bin) from the download directory to /lib/firmware/rtlwifi/
* reboot to activate the firmware (you can wait with this step, make it after step 2)

git clone https://github.com/lwfinger/rtl8188eu.git
mkdir -m=777 -v -p /lib/firmware/rtlwifi/
cp rtl8188eu/rtl8188eufw.bin /lib/firmware/rtlwifi/
chmod 444 /lib/firmware/rtlwifi/rtl8188eufw.bin
reboot

The success of this step means that the device is recognized (lsusb lists it like below).

-bash-4.2# lsusb
Bus 001 Device 004: ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter

= Step 2: Activate the corresponding kernel module =

Check if the kernel module is loaded with lsmod. Probably it is not, so you have to:
* download the kernel module

wget https://dl.dropboxusercontent.com/u/80256631/8188eu-20160319.tar.gz ''' -> is anyone out there able to provide a better link as the dropbox?'''
tar xzvf 8188eu-20160319.tar.gz
cp 8188eu.conf /etc/modprobe.d/ ''' -> disable power management'''
cp 8188eu.ko /lib/modules/4.1.20+/kernel/drivers/net/wireless/8188eu.ko ''' -> copy the kernel module to the proper location'''
chmod 644 /lib/modules/4.1.20+/kernel/drivers/net/wireless/8188eu.ko
reboot ''' -> alternatively you can use modprobe and insmod to activate it on the fly if see the device with lsusb, i.e. rebooted after step 1'''

Now lsmod should list the

-bash-4.2# lsmod
Module Size Used by
8188eu 931781 0

ifconfig -a should list the device and provide you with the MAC address and the device id (e.g. wlan0).

= Step 3: the ifcfg-wlan0 file =

setup the /etc/sysconfig/network-scripts/ifcfg-wlan0 file

NAME="wlan0"
DEVICE=wlan0
HWADDR=XX:XX:XX:XX:XX:XX '''<- put the MAC of the WiFi Adapter here, you can get it with ifconfig'''

# DHCP Version --------------------
USERCTL=yes
NM_CONTROLLED=no
ONBOOT=yes
BOOTPROTO=dhcp
# Fixed IP version ----------------
#IPADDR=192.168.1.10
#GATEWAY=192.168.1.1
#NETMASK=255.255.255.0
#BOOTPROTO=static
# Wireless configuration ----------
TYPE=Wireless
MODE=Managed
# Settings provided by WPA Supplicant, not needed here
#ESSID="XXX"
#RATE=54Mb/s
IPV6INIT=no
IPV4_FAILURE_FATAL=no
IPV6_FAILURE_FATAL=no

= Step 4: configure wpa-supplicant =

The wpa-supplicant is needed to authenticate into WAP secured networks. If you are using a network without security it is not needed. But hopefully no one is exposing his network, so I document it here for WPA2 encryption.
* generate the passphrase
wpa_passphrase "Your Wireless SSID" testpassword > /root/wirelesspassword.conf

now you have in /root/wirelesspassword.conf

network={
ssid="Your Wireless SSID"
#psk="testpassword" '''<- delete this line since it lists your password in clear text! You do not need it, the passphrase is enough'''
psk=5badfeae3f0f83a75f58cb18d2e483c6a72b1f3c13f2b7402747ad0d406b5d30
}

configure other options in /etc/wpa_supplicant/wpa_supplicant.conf

-bash-4.2# cat /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=root
country=DE
mac_addr=0 '''-> I had once problems with a network that used also MAC Filtering. This helped. '''
preassoc_mac_addr=0 '''-> I had once problems with a network that used also MAC Filtering. This helped. '''

network={
ssid="RAC Home"
proto=WPA RSN '''-> use WPA2 with AES'''
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
}

= Step 5: autostart the wpa-supplicant and the dhclient =

Add the wpa-supplicant and dhclient at the end the ifup script for wireless in /etc/sysconfig/network-scripts/ifup-wireless

wpa_supplicant -Dwext -iwlan0 -c /root/wirelesspassword.conf -B
dhclient wlan0

= Step 6: ativate the wireless adapter and connect to network =

Manually you start it by calling
-bash-4.2# ifup-wlan0

I start my network in /etc/rc.d/rc.local by explicitely calling ifup wlan0, if it does not start. (too lazy to find out what service does it really and activate it). Please post you questions on the discussion page. Feel free to improve the page if you wish (need to login to the wiki).

wget https://dl.dropboxusercontent.com/u/80256631/8188eu-20160319.tar.gz ''' -> is anyone out there able to provide a better link as the dropbox?'''
tar xzvf 8188eu-20160319.tar.gz
cp 8188eu.conf /etc/modprobe.d/ ''' -> disable power management'''
cp 8188eu.ko /lib/modules/4.1.20+/kernel/drivers/net/wireless/8188eu.ko ''' -> copy the kernel module to the proper location'''
chmod 644 /lib/modules/4.1.20+/kernel/drivers/net/wireless/8188eu.ko
reboot ''' -> alternatively you can use modprobe and insmod to activate it on the fly if see the device with lsusb, i.e. rebooted after step 1'''

Now lsmod should list the

-bash-4.2# lsmod
Module Size Used by
8188eu 931781 0

ifconfig -a should list the device and provide you with the MAC address and the device id (e.g. wlan0).

= Step 3: the ifcfg-wlan0 file =

setup the /etc/sysconfig/network-scripts/ifcfg-wlan0 file

NAME="wlan0"
DEVICE=wlan0
HWADDR=XX:XX:XX:XX:XX:XX '''<- put the MAC of the WiFi Adapter here, you can get it with ifconfig'''

# DHCP Version --------------------
USERCTL=yes
NM_CONTROLLED=no
ONBOOT=yes
BOOTPROTO=dhcp
# Fixed IP version ----------------
#IPADDR=192.168.1.10
#GATEWAY=192.168.1.1
#NETMASK=255.255.255.0
#BOOTPROTO=static
# Wireless configuration ----------
TYPE=Wireless
MODE=Managed
# Settings provided by WPA Supplicant, not needed here
#ESSID="XXX"
#RATE=54Mb/s
IPV6INIT=no
IPV4_FAILURE_FATAL=no
IPV6_FAILURE_FATAL=no

= Step 4: configure wpa-supplicant =

The wpa-supplicant is needed to authenticate into WAP secured networks. If you are using a network without security it is not needed. But hopefully no one is exposing his network, so I document it here for WPA2 encryption.
* generate the passphrase
wpa_passphrase "Your Wireless SSID" testpassword > /root/wirelesspassword.conf

now you have in /root/wirelesspassword.conf

network={
ssid="Your Wireless SSID"
#psk="testpassword" '''<- delete this line since it lists your password in clear text! You do not need it, the passphrase is enough'''
psk=5badfeae3f0f83a75f58cb18d2e483c6a72b1f3c13f2b7402747ad0d406b5d30
}

configure other options in /etc/wpa_supplicant/wpa_supplicant.conf

-bash-4.2# cat /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=root
country=DE
mac_addr=0 '''-> I had once problems with a network that used also MAC Filtering. This helped. '''
preassoc_mac_addr=0 '''-> I had once problems with a network that used also MAC Filtering. This helped. '''

network={
ssid="RAC Home"
proto=WPA RSN '''-> use WPA2 with AES'''
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
}

= Step 5: autostart the wpa-supplicant and the dhclient =

Add the wpa-supplicant and dhclient at the end the ifup script for wireless in /etc/sysconfig/network-scripts/ifup-wireless

wpa_supplicant -Dwext -iwlan0 -c /root/wirelesspassword.conf -B
dhclient wlan0

= Step 6: start the card if necessary =

Manually you start it by calling
-bash-4.2# ifup-wlan0

I start my network in /etc/rc.d/rc.local by explicitely calling ifup wlan0, if it does not start. I am too lazy to google after what service does it really in fedora and check if it is activated.

AZImage help - Quickstart - Adding formats

2011-06-23T16:53:49Z

WikiRAdmin: Initial version

[[Category:AZImage]]
You are here > [[AZImage help index | Index]] > [[AZImage help - Quickstart | Quickstart]] > '''Adding formats'''

<br />
----

An AZImage format contains all transformations that have to be applied to the source files to obtain the final output images. This includes the size of the new image, the image format (e.g. JPEG, GIF, ...) and so on.

You can have multiple formats defined. For your convenience, you can select only some of the formats when converting the images. The basic idea behind is to keep all formats in the list and each time select only the ones you need for the particular conversion. This approach simplifies the management of formats and in the end saves time.

The list shows the most important properties of the formats. From left to right they are:

* active check box - checked if a format is active

* final file format for the output images

* transformations defined for the format (resize, brightness, grayscale, etc.)

* output path - the directory where the output images are saved

The toolbar buttons for the formats tab are sef explanatory:

Add Format opens a dialogue where the new format can be defined, if wanted also saved to a file for later reuse. By default a preselection box is displayed. It allows you to quickly setup the most important parameters based on what you want to do with the images later. For example if you select Facebook the maximum width of the output image is restricted to 604 pixels, that is the maximum that facebook currently supports.

Edit Format opens the same window, but with the settings of the format already loaded. You can modify them and then close the window to apply them to the format in the list.

Delete removes the selected formats from the list. If by accident some of the still needed formats are removed, you can use the Undo button to restore them.

Deactivate All will deactivate all formats. Note that only active (checked) formats are used during the conversion.

Save and Load will store, respectively retrieve the format list to/from a file.
