TP-Link TL-WN725N unable to get wifi working
I looked through all the other topics regarding that specific wifi dongle but nothing worked. I'm on RC3 3.15.8+ kernel.

What i tried:

- Scanning for Network (no SSID's found)
-manually adding SSID and password through xbian-config (Cannot connect to network.)

Additional:
-wifi dongle is ok. it works on my laptop and also it worked in openelec

lsusb:
Code:
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 004: ID 0bda:8179 Realtek Semiconductor Corp.

ifconfig:
Code:

RE: TP-Link TL-WN725N unable to get wifi working
sure, my bad i didnt post that at the first place. here you go:

/etc/network/interfaces
Code:
auto lo
iface lo inet loopback

iface eth0 inet dhcp

auto wlan0
allow-hotplug wlan0
iface wlan0 inet static
address 192.168.2.12
netmask 255.255.255.0
gateway 192.168.2.1

and my dmesg here

also the led on my adapter does not even blink. if that matters anyway

RE: TP-Link TL-WN725N unable to get wifi working
it appears that this does not work either.

EDIT:

i finally got it working by running:
thanks to @menakite
Code:
sudo mkdir /lib/firmware/rtlwifi; sudo wget -O /lib/firmware/rtlwifi/rtl8188efw.bin https://github.com/OpenELEC/wlan-firmware/blob/master/firmware/rtlwifi/rtl8188efw.bin?raw=true

sudo wget -O /lib/firmware/rtlwifi/rtl8188eufw.bin https://github.com/OpenELEC/wlan-firmware/blob/master/firmware/rtlwifi/rtl8188eufw.bin?raw=true

and editing my /etc/network/interfaces to:

Code:
auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp

and my /etc/wpa_supplicant/wpa_supplicant.conf to:

Code:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
        ssid="NETWORK_NAME"
        psk="NETWORK_PASSWORD"
}

thanks for the help guys!

RE: TP-Link TL-WN725N unable to get wifi working
Yep, that'd be the next test.

Unfortunately Debian Wheezy (stable release) is not packaging this firmware - it's only available in the next stable - so installing firmware-realtek doesn't have any effect.

For this you have to change your repo. Check this http://www.xbian.org/faq/

For a wep password do you know how to do ?

RE: TP-Link TL-WN725N unable to get wifi working
@Uhsac

if you manage the fw download to /lib/firmware folder then wlan0 should appear after reboot and use xbian-config settings network to configure

the trick is only with missing .fw
