Retropie 3 – wifi TL-WN725N

[carlux3]

Hello,

I installed a retropie 3 on a Rpi2, I’d like to connect it in wifi. I have wifi dongle TP-Link : TL-WN725N which should be working but it doesn’t.
When I go through the Retropie Wifi Menu it doesn’t detect any wifi network.
I try to follow some topics here but without success ….
I try to change the /etc/network/interfaces, but it didn’t change anything :

auto lo

iface lo inet loopback
iface eth0 inet dhcp
allow-hotplug wlan0
auto wlan0
#iface wlan0 inet manual
iface wlan0 inet dhcp
#wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
#iface default inet dhcp
wpa-ssid Numericable-f1f2
wpa-psk **********

it seems the wlan0 is not detected.

Do you have an idea ?

Did you try this:

No wireless networks found

Is your encryption WPA or WEP? Your interfaces file will be different depending on your encryption.

Hello,

Yes I did but it doesn’t help.

My encryption was : WPA-PSK [TKIP] + WPA2-PSK [AES] and changed it to WPA2-PSK [AES] and then to WPA-PSK [TKIP] but nothing changed

if I do a ifconfig, the wlan0 doesn’t appear.

Do I need to put the SSID and pasword between “” ?

if I do ifup wlan0 :

pi@retropie ~ $ sudo ifup wlan0
wpa_supplicant: wpa-roam can only be used with the "manual" inet METHOD
run-parts: /etc/network/if-pre-up.d/wpasupplicant exited with return code 1

Typically mine has double quotes like the example listed under option 2 here:

https://github.com/RetroPie/RetroPie-Setup/wiki/Setting-Up-Wifi

See if adding double quotes changes anything.

If its not even showing try sudo ifconfig wlan0 up

see result below :

pi@retropie ~ $ sudo ifconfig wlan0 up
wlan0: ERROR while getting interface flags: No such device

sounds like its a driver issue then rather than your configurations. seems you’re not the only one who has had issues with the same wifi dongle:

from that forum link I posted you could try this:
sudo wget https://github.com/lwfinger/rtl8188eu/raw/c83976d1dfb4793893158461430261562b3a5bf0/rtl8188eufw.bin -O /lib/firmware/rtlwifi/rtl8188eufw.bin

sudo reboot

and then use wpa supplicant along with interfaces detailed here:

I would just buy a new wireless dongle, one that has a well supported chipset. No point fighting each time with drivers when you can pick them up for a few pounds.

On my old RP1 i had a TL-WN725N too.
You have to install the driver manually and every time again after a stystem update.

Thanks, but still nothing :'(

can you tell which driver you use and how you install it ?

cheers

[muffy]

Press F4 and read your actual Linux version.
For example Linux 3.12.22+.
Then you have to google for the driver. Every new Linux version needs an own driver for the TL-WN725N.

For the installing i used this tutorial:

Unfortunatly nothing works … I’ll see to buy a new dongle…

Thanks
