Raspberry Pi • View topic - Access Point (AP) for TP-Link TL-WN725N V2

by **saliamis** » Sat Sep 07, 2013 10:10 am

Hi all,

I have successfully configured the TP-Link TL-WN725N V2 WiFi module (chipset RTL8188EU) as an AP (access point).
Have tried many tutorials out there, but none worked for me (hostapd failures with bad wifi driver).

This tutorial is based upon these sources (with some exceptions):
RPI-Wireless-Hotspot
Wifi-hotspot-with-edimax-nano-usb

Since I used the module to control a robot through WiFi, I didn't setup a bridge to share internet connection (hotspot).
If you want to share/access internet through the AP, then look how to make a bridged connection in the above sources.

Steps that helped me to configure a non-bridged AP:

1. Install hostapd & dhcp server

Code: Select all: apt-get install hostapd udhcpd

2. Edit /etc/udhcpd.conf, set its contents like this:

Code: Select all: start 192.168.42.2 # This is the range of IPs that the hostspot will give to client devices. end 192.168.42.20 interface wlan0 # The device uDHCP listens on. remaining yes opt dns 8.8.8.8 4.4.4.4 # The DNS servers client devices will use. opt subnet 255.255.255.0 opt router 192.168.42.1 # The Pi's IP address on wlan0 which we will set up shortly. opt lease 864000 # 10 day DHCP lease time in seconds

3. Edit /etc/default/udhcpd, set the following line to be like this:

Code: Select all: #DHCPD_ENABLED="no"

4. Set wlan0 static IP, edit /etc/network/interfaces, contents should look like this:

Code: Select all: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp # WiFi AP auto wlan0 iface wlan0 inet static address 192.168.42.1 netmask 255.255.255.0 post-up service udhcpd start #allow-hotplug wlan0 #iface wlan0 inet manual #wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf #iface default inet dhcp

5. Replace hostapd with a modified binary:

Code: Select all: wget http://www.daveconroy.com/wp3/wp-content/uploads/2013/07/hostapd.zip unzip hostapd.zip mv /usr/sbin/hostapd /usr/sbin/hostapd.bak mv hostapd /usr/sbin/hostapd chmod 755 /usr/sbin/hostapd

Alternative link: https://www.dropbox.com/s/u4lt7k6ko4i6589/hostapd.zip
NOTE: if you want to compile the binary for yourself, then go here & download RTL8192CUS driver. Navigate inside zip to the wpa_supplicant_hostapd/wpa_supplicant_hostapd-0.8/hostapd and run: make, make install, then copy as above.

6. Edit /etc/hostapd/hostapd.conf, contents should look like (change "RPI_AP" to the desired AP name, "AP_PASSWORD" - to desired password):

Code: Select all: interface=wlan0 driver=rtl871xdrv ssid=RPI_AP hw_mode=g channel=6 macaddr_acl=0 auth_algs=1 ignore_broadcast_ssid=0 wpa=2 wpa_passphrase=AP_PASSWORD wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP rsn_pairwise=CCMP macaddr_acl=0

7. Edit /etc/default/hostapd, set the line to be:

Code: Select all: DAEMON_CONF="/etc/hostapd/hostapd.conf"

8. Run hostapd:

Code: Select all: service hostapd start

9. Allow hostapd to be run everytime on boot:

Code: Select all: update-rc.d hostapd enable

10. Reboot your RPi

Code: Select all: reboot

Finished! You should now have a fully working AP (with WPA2-PSK security) that you can connect to.
I have successfully tested with my Android phone.

Hi Saliamis,
I have a model A, without ethernet, and a brand new TP-LINK WN725N v2, with the last chipset.
I did al your steps without errors, and after rebooting I see even the new created Access Point ("RPi_AP"), but I unable to connect. Services 'udhcpd' and 'hostapd' seem to run as service. I try to connect with my iPhone, but it gives a connection error.
Do you have any idea where to start looking?

by **jamkirbs** » Thu Oct 17, 2013 11:54 pm

Do this chipset support mac address filtering in hostapd? thanks!

Hi,
Thanks for the tutorial. I was able to setup AP. I can see it on my laptop wifi n/w list as well as Galaxy S3. I was able to connect to AP from laptop, however Galaxy S3 could not connect. It just gets stuck saying "Obtaining IP address...".

any clue ?

I have updated the /etc/network/interfaces file contents, check it out. If it still does not work, add hotplug option:

Code: Select all: allow-hotplug wlan0 auto wlan0

Thanks for suggestion. I have tried it but no luck. Looks like rtl 8188 chipset's AP capability is in testing phase (not officially released). I will try the same with Ralink rt 5370 and update results.

Worked without a problem with Ralink rt 5370. Able to connect android phone as well as laptop.

Hello all,

Did not work for me...
My setup is: Raspberry Pi Model B with TP-Link TL-WN725N v2 (0bda:8179)
Running Raspbian: 3.1.23+ #608 PREEMPT Mon Dec 9 21:11:23 GMT armv61 GNU/Linux
with appropriated dongle drivers from MrEngmann.

Executing command:
$ sudo hostapd -dd /etc/hostapd/hostapd.conf

I get the following:

As you can see, I get a lot of Failed steps; all as ioctl[RTL_IOCTL_HOSTAPD]: Operation not supported.

Any ideas of what could be the reason behind this behavior? Thank you.

Best regards to all,
Emmanuel.

$ unzip hostapd.zip
$ sudo mv /usr/sbin/hostapd /usr/sbin/hostapd.bak
$ sudo mv hostapd /usr/sbin/hostapd
$ sudo chmod 755 /usr/sbin/hostapd

Starting it all:

$ sudo service hostapd start
$ sudo service udhcpd start

Enabling hostapd and udhcpd to start at each Pi's boot:
Since the IP address mentioned in interfaces files wasn't assigned to wlan0 in every boot (bizarre), I had to come up with the following workaround. This, because without an IP assigned to wlan0, the DHCP deamon wouldn't start, thus the Pi wouldn't distribute an IP to any client willing to pair with your Pi.

$ sudo update-rc.d hostapd enable
$ sudo nano /etc/rc.local
sudo ifconfig wlan0 192.168.2.1
sudo service udhcpd start
$ sudo reboot

I hope this post can be of some help.

Best regards,
Emmanuel.

Hello all,

I just edited my previous post with the solution to my troubles.
All is working fine now.

Best regards,

What was the performance of RTL8188EU as access point? could you measure the throughput?

Hi,

I am not an expert in Network Programming. If you can point some method to measure the performance, I can measure it for you and post the results.

However, from my point of view, I have no complaint about the RTL8188EU as an access point.

Best regards,
Emmanuel.

Hi, I successfully run a accesss point but whit this wide (many tanks!!!!!). Also I install minidlna in the raspberry but my smarth tv or my phone cant see any file with the wifi connexion of the pi. If I connect my phone with the wifi of the modem I see any media file of my pi. How can I do? Many thank and sorry for my english.

I followed each step in this post and I can find the wifi network now. However, it has verify issue when I connect to that network. It look like I input a wrong password. Anyone know how to solve it?

I have a error too. You can use this config for hostapd.conf

sudo nano /etc/hostapd/hostapd.conf

interface=wlan0
driver=rtl871xdrv
ssid=WLAN-NAME
channel=1
hw_mode=g

And you can connect to AP.

I don't understand when i config my hostapd

interface=wlan0
driver=rtl871xdrv
ssid=raspi
hw_mode=g
channel=6
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=12345678
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP

I can't connect to my AP with my phone, laptop...v.v... Wrong password... !!!!!.... why ?......................

Hello
I have the same problem,
before all is working but with last kernel update 4.1.7+ #817
if I set a wep any device can't connect to the AP.
If I set open Access Point all is working.

I use TP-Link TL-WN725N V2 with kernel version 3.18.11-v7+ #781 on Pi2.

This instruction is not work for me, but I found the problem came from its driver. I use driver from this http://blog.mac.boy.name/2015/04/tl-wn725n-v2-access-point-ap-for.html and it works for me. I can connect to Pi2 either PC and my smartphone(BB Z10).

Hi... can you set password for host..?...

by **renoir** » Tue Dec 08, 2015 8:05 am

Tried this, but it seems to not work on the Pi 2 B with:

Code: Select all: Linux raspberrypi 4.1.7-v7+ #817 SMP PREEMPT Sat Sep 19 15:32:00 BST 2015 armv7l GNU/Linux

The APN shows up, but you couldn't connect to it because it doesn't recognize the password.

If you remove the password it won't lease you an IP.

If anyone has solved this please share. For now this tutorial should be marked not working form this version of Raspbian.
