Wifi setup with the TP Link WN725N

[loko]

I am having problems with setting up my wifi with the WN725N wifi adapter. So I got tried this out:

Code: Select all

auto lo

iface lo inet loopback
iface eth0 inet dhcp
allow-hotplug wlan0
iface wlan0 inet dhcp

        wpa-ssid "mynetworkid"
        wpa-psk "mynetworkpassword"

Then I rebooted the raspberry Pi and put my adapter in. It did nothing. I couldn't use the browser and the adapter doesn't seem to be on.

Am I doing something wrong? I can't use ethernet at the moment. So can someone help me fix this problem?

[amiasnikov]

Try hotplug usb WiFi adapter when OS have booted.

and if no connection look at /var/log/messages about errors

There are two versions of this wifi adaptor. V1 has the driver included in most images, V2 requires you to download and install a driver as it is not included in the Linux images.

It appears you probably have V2 and need to download and install the driver. You can determine the wifi version you have if you use command lsusb. This will list the WN725N V2 as

Code: Select all

Bus 001 Device 004: ID 0bda:8179 Realtek Semiconductor Corp.

The important info is the ID 0bda:8179.

If it shows this you need to download the driver. If you use a recent version of Raspbian there are precompiled versions available.

Precompiled versions of the driver are available for Raspbian as follows
for 3.6.11+ #538, #541, #545, #551 and #557 use 8188eu-20130830.tar.gz
for 3.6.11+ #524, #528 or #532 use 8188eu-20130815.tar.gz
for 3.6.11+ #371 up to #520 use 8188eu-20130209.tar.gz

Use command uname -a to determine the version you have e.g.

Code: Select all

pi@raspberrypi ~ $ uname -a
Linux raspberrypi 3.6.11+ #551 PREEMPT Mon Sep 30 14:42:10 BST 2013 armv6l GNU/Linux
pi@raspberrypi ~ $

Download and install the driver using the commands

Code: Select all

wget https://dl.dropboxusercontent.com/u/80256631/8188eu-2013xxyy.tar.gz <--set data code for driver version above
tar -zxvf 8188eu-2013xxyy.tar.gz                                         <--set data code for driver version above
sudo install -p -m 644 8188eu.ko /lib/modules/3.6.11+/kernel/drivers/net/wireless
sudo insmod /lib/modules/3.6.11+/kernel/drivers/net/wireless/8188eu.ko
sudo depmod -a

When I try the sudo install comman, it does nothing. Same with the commands after that.

[MrEngman]

Sorry but I can only be contacted via the forum or PM.

From your first post you seem to have set up the file /etc/network/interfaces correctly assuming your network uses WPA/WPA2 security.

The main problem will be to get the driver onto the SD card. There is some additional info at the bottom of the page at http://www.fars-robotics.net/ for getting the driver onto the SD card if you have no internet connection to your Pi.

Have you verified your wifi is WN725N V2? i.e. ID 0bda:8179

Sorry doesn't help. Can you plug it into your Pi and run the command lsusb to check the usb devices. It should show the wifi adaptor and if it is V1 or V2.

That sounds encouraging.

You can check if the driver is loaded OK with command ifconfig It should show wlan0 something like

Code: Select all

wlan0     Link encap:Ethernet  HWaddr a0:f3:c1:25:7d:28
          inet addr:192.168.16.15  Bcast:192.168.16.255  Mask:255.255.255.0

          TX packets:5821 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:21001551 (20.0 MiB)  TX bytes:762826 (744.9 KiB)

If the wifi is connected it will have an entry for inet addr:.

You can also check using command sudo iwlist wlan0 scan. This should display a list of wireless networks your wifi can see if it is working.

It did work! Thank you very much

I have a model A, with a V2 TP link WN725n, and I have tried to get this working to no avail. I have tried 2 different versions of Wheezy, and loading the driver manually. I get as far as seeing the module with lsmod, but it will not configure or scan. I tried the NOOBS image, and it wouldn't even boot. Then I tried an image of Wheezy with the driver built in, and I get the same results. And to boot, I get I/O errors trying to use usb sticks now, which was working, and the keyboard is sticking. I can't get it to connect to anything, so I can't update it. I guess this Pi will probably wind up on the scrap heap, as I can't keep wasting money on buying parts that MIGHT work. I love LINUX and had hopes for this little computer for a number of projects, but this has been a real disappointment so far.

[tanis126]

If it helps, using the image from http://cassidy.pi3g.com/rpi_images/rasp ... x130523.7z,
and getting rid of a questionable hub, I got it working.

Hi

I have the V2 of the wifi dongle, lsusb tell me

Code: Select all

Bus 001 Device 004: ID 0bda:8179 Realtek Semiconductor Corp.

I have followed all the instruction installing "8188eu-20130830.tar.gz" since uname -a give me

Code: Select all

Now the blue led is on, but when I execute ifconfig the result is this:

Code: Select all

wlan0     Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx          (I masked the HWaddr)  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0

          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

What am I doing wrong?
With another sdcard I have installed Openelec and I made the wifi dongle work using some help from the net, but I was not successful with Raspian.

Any help?

Thanks
Vittorio

I found by myself the answer.

Since I have an hidden SSID, I found this helpful.

Just made some edit in the /etc/network/interfaces as below:

Code: Select all

auto lo

   wpa-pairwise CCMP TKIP
   wpa-group CCMP TKIP
   wpa-ssid "My Secret SSID"

That is the wrong driver version. Take a look here for details and don't forget to install the separate firmware file.

Since I have an hidden SSID, ..

I have to ask what do you think you gain by doing that?

If you say, "security" I will find you, I will be armed with my educational baseball bat.

Hiding SSID does nothing, it is not worth the hassle.

Been following this post as I have firmware and driver issues as well. Last couple days I just got my pi v2 model B, successfully loaded with Noobs but wifi is just not working because of no drivers. I have dongle Edimax EW-7811Un which has 3.10.25+ #622 8188eu. I can successfully down load the files using wired ethernet but when I try to load them Raspberry reports back with "directory or file does not exist". Followed this http://www.fars-robotics.net/ and this http://www.mendrugox.net/2013/08/tp-lin ... y-raspbian/ in attempt to install drivers. When using the wifi-config gui when trying to connect it reports that driver has failed to load.

Could someone please help and describe how I locate or create the directories necessary to install the wifi firmware and drivers with no luck. Since I have noobs on the SD card I can see the os files using windows, is it possible to copy/paste the driver files using windows? If not what is the proper method?

edit 4/9/14 Just learned that Noobs has built in support for the Edimax wifi dongle from here http://docs.brewpi.com/installing-your- ... setup.html going to attempt to disable power management as described in link to see if that makes a difference.

Please chime in if anyone has a better idea of how to resolve this.

Thanks so much

NOOBS itself does NOT have support for wifi. It is the images that NOOBS loads that support wifi.

Now you say your dongle is "Edimax EW-7811Un which has 3.10.25+ #622 8188eu". Why?

The EW-7811Un uses the Realtek rtl8188cus wifi and the rtl8188cus driver (named 8192cu) is included in all Linux images that NOOBS loads AFAIK.

The 8188eu driver is used by a different version of wifi dongles - TP-Link TL-WN725N V2.

Install NOOBS on your SD card and boot NOOBS. It will ask for the image you want to load which I assume is Raspbian. Load Raspbian and NOOBS will then reboot and Raspbian will start. When Raspbian boots it will run raspi-config so do any set up you want and then reboot to restart Rasbian.

Raspbian will then reboot and after logging in you can set up the wifi by just editing file /etc/network/interfaces as in http://www.fars-robotics.net/. Such as

Code: Select all

auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet dhcp    }
wpa-ssid "wifi-name"     } add these three lines
wpa-psk "wifi-password"  }

# and delete or comment out these lines
#iface wlan0 inet manual
#wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
#iface default inet dhcp

which is probably the simplest setup.
