[PROBLEM] TP-Link TL-WN725N unable to get wifi working

[Maylo]

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

Same problem for me !

Can you post the output of /etc/network/interfaces

and also the output of dmesg via http://www.pastebin.com

[Maylo]

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

[menakite]

Can you try

Terminal

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

and reboot.

[Uhsac]

This don't work for me, it still don't appear with ifconfig

[Maylo]

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!

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.

[Maylo]

yea, i noticed. by the way for some strange reason i cannot update my distro. it says that the sources are unreachable. is there any solution to that?

[Uhsac]

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 ?

@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
