How to install tp-link :TL-WN725N wireless nano usb adapter

Tue Apr 23, 2019 4:44 am

Hello!
I am using a raspberry pi b+ which does not have a wifi interface in it.
so I bought a tp-link TL-WN725N wireless nano USB adapter (version 3) in Amazon:
https://www.amazon.in/TP-Link-TL-WN725N ... 280&sr=8-3

I am unable to set it up on my pi

can you please help me out by giving detailed information on how to set it up?

Thanks for helping me in advance.

I suspect there is someone here who can help with drivers for that adaptor, but first it is essential to determine exactly which chipset that adapter uses (It can vary. Sometimes manufacturers will switch the chips inside their adaptors and produce new Windows drivers and not tell anybody).

So, with the USB adaptor unplugged:
Start a Terminal session on the Pi (or just from the command line if you are not using a desktop).

Type lsusb (that's lower-case LSUSB) and note what is displayed. That is the default USB setup of your Pi.

Plug in the USB adapter and wait a few seconds.

Type lsusb again. There should be an extra line that gives some details about the adapter. Post the full contents of that line and someone will advise if/how the adapter can be used. Hopefully it is one of the ones that MrEngman provides drivers for. They are very common.

See this thread for how to install drivers. viewtopic.php?f=28&t=62371

It is long because it keeps getting updated for newer versions, but the general advice should work and if it doesn't, then skip to the end and leave a comment with what you tried and what happened.

Bro, I have looked into the website and I think there are no drivers in the list

my kernel version is
Linux raspberry pi 4.14.98+ with build #1200

NO drivers for build #1200 in the list.

I am so sorry I am troubling you on holiday!
I am just a bit worried because I have to complete my project before the 25th of May.
so help me with this in your spare time.
I downloaded the drivers from MrEngman's website and moved them to my raspberry pi desktop and extracted them. when I try to install it is showing me an error.

I think you have missed the point that the vast majority of assistance in these forums is indeed provided by volunteers helping during their spare time.

You also seemed to have not realised that you have already had advice directly from the forum user whose knowledge of these matters far exceeds that available from any other source.

So it might be wise to take heed of the instructions concerned with installing these drivers:
The driver installation instructions expect you to be using Raspbian, either installed from a basic raspbian image or installed using NOOBS. The instructions are based on running from a Command Line Terminal, not a GUI (Graphical User Interface). If you are running using the GUI you will need to open a terminal window and run the commands from the terminal window but I can't guarantee they will work.

Your screenshot appears to show that you are attempting to proceed using the graphical File Manager from the Raspbian Desktop GUI?

If time is of the essence, following the documentation provided for your benefit will probably be faster than firing off multiple questions to these forums and having to wait for replies. Another route to a quick solution would be to purchase a WiFi dongle that is known to be supported by Raspbian with no additional configuration.

I think you need to open a terminal window, cd to the directory where the driver has been unzipped, and run the install.sh command in the terminal window.

After installing the driver you will need to configure your wifi to connect to your wifi network using /etc/wpa_supplicant/wpa_supplicant.conf. Set up wpa_supplicant.conf like

Code: Select all

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=GB

network={
	ssid="network-name"
	psk="network-password"
}
Set network-name and network-password to your network settings and If you are not in the UK you will need to change the line country=GB to the country where you are.

I hope it's not bad form to wake an old thread, but the topic is so relevant it seems sensible.

I've been able to follow tips on this wonderful forum to install the TL-WN725N working (at least in one use case).

I have a Pi 1 A+ that I want to use as a headless device, therefore I need to access and control it via ssh.
The particular challenge I'm having is that the Pi 1 has only one USB port, so either the wireless adapter or the keyboard is possible but both.
In order to get all the ssh and wireless configured, I used my Pi 3.

buster lite is installed on the SD card, and everything (remote ssh login and wireless) works as expected on the Pi 3. The bootup messages display the ip address. I can ssh using the device name or the ip address.

Then I transferred the card to the Pi 1 A+ and boot, and ... no dice. The device never shows up on my "connected devices" list on the router, and unlike when booting on the Pi 3, the ip address is not shown in the bootup messages.

Boot messages DO say:
started WPA_supplicant
started dhcpcd on all interfaces
Reached target network
Started OpenBSD Secure Shell server

I read in another thread that interchanging cards should work. Both Pi's are recent purchases. The Pi 3 about a year ago and the Pi 1 A+ last month.

Any insights would sure be appreciated!

If you installed the 8188eu wifi driver using my install-wifi script on the Pi 3 it would install the driver version 8188eu...-v7+, with -v7+ in the filename. On the Pi 1 A+ it needs the driver 8188eu...+, note no -v7 in the filename.

You can install the driver for the Pi 1 A+ by putting the SD card back in the Pi 3 and then download the 8188eu...+ driver matching the info from command uname -a minus the -v7 in the filename from my web site. Then untar the driver file and run command ./install.sh which will install the driver for the Pi 1 A+.

You should then find when you put it in the Pi 1 A+ it should work. Just tried it myself to check it works and it does.

If necessary, if you post the output from command uname -a I can provide the exact commands you need to execute to download and install the Pi 1 A+ wifi driver.

Thank you for such a timely reply and offer of help.

"post the output from command uname -a I can provide the exact commands you need":
Linux PI-SPRINKLER 4.19.97-v7+ #1294 SMP Thu Jan 30 13:15:58 GMT 2020 armv71 GNU/Linux

If I understand your instruction, the driver I need is:
4.1.15+ #830 - 8188eu-20151216.tar.gz

from the pi 3 with functional wi-fi I tried:
wget https://dl.dropboxusercontent.com/u/802 ... 216.tar.gz, but got a 404 not found error

oops ... just saw the other thread with the URL on your own web site. I'll try with that and report back asap

update: using wget to fars-robotics with https it times out and with http I get 404 (it does make the connection to fars-robotics.net; perhaps I have selected the wrong file)

The file you need is 8188eu-4.19.97-1294.tar.gz.

Use commands

Code: Select all

wget http://downloads.fars-robotics.net/wifi-drivers/8188eu-drivers/8188eu-4.19.97-1294.tar.gz
tar xzf 8188eu-4.19.97-1294.tar.gz
./install.sh

:-)

I can now move on to the next phase in my project.

FYI, the PI is on the network as its name with a '-1' appended. I presume that is because there are now 2 drivers, one that activates depending on which Pi it is in.

Thank you for your generosity in helping.

Hello again,
I had the wireless working, and then I assembled it with a sprinkler controller board (https://opensprinkler.com/product/opensprinkler-pi/), at which point the wireless does not work. The Pi 1A+ gets its power from that board. Prior to assembling with the board, I updated all the Pi software (apt-get update, etc) and installed the software that goes with the sprinkler board. The networking and web server worked fine.
Then I mated the Pi to the sprinkler controller board, and the wireless did not work (no ip address shown at bootup).
Next I removed the Pi and powered with the USB port, and still no wireless.
Then I again put the sd card in a Pi 3, and wireless works.
Then assembled the Pi 3 with the sprinkler control board, and everything works, wireless, software and solenoid control.

So, it boils down to how much trouble is it worth to keep trying to use the Pi 1A+, which I selected for its minimal capability to do one simple thing.

I can think of a few options now:
1) find some configuration problem (I'd need expert input for this one)
2) Try a wi-fi dongle used with Pi (I guess this one isn't; I just saw one and bought it)
3) Buy a small Pi with wireless built in
4) Use the Pi 3 (just seems like so much overkill for the task, and grates on me to give up on solving the problem, but it's already past the point of being anything like time-efficient. I know it takes time to learn new things, but I'm close to not caring about the best solution and willing to stick anything in there that works.

If you have any ideas for troubleshooting, I'd appreciate hearing them.
