Download to your default home directory - probably /home/pi.

The easy way to get there is to just use the command

Code: Select all

cd
then run all the install commands from there.

Re: (UPDATE) Drivers for TL-WN725N V2 - 3.6.11+ -> 3.10.32+

Tue Mar 04, 2014 4:28 pm

Hi MrEngman
I wonder if you can help me?
I am trying to get the WN725N working with WiFi Direct for the Piracast (Miracast on Pi) Beta Release and although I had it working once, I have since reinstalled Rasbian to 3.10.32+ #648 and it no longer works. It does connect, but seems to fall over when loading the p2p_hostapd.conf file.

The syslog reports:-
Mar 4 00:16:13 raspberrypi ifplugd(wlan0)[2291]: Using interface wlan0/C0:4A:00:18:2E:96 with driver <rtl8188eu> (version: )
Mar 4 00:16:13 raspberrypi ifplugd(wlan0)[2291]: Using detection mode: wireless extension
Mar 4 00:16:13 raspberrypi ifplugd(wlan0)[2291]: Initialization complete, link beat not detected.

Just so that I can rule out the driver, could you please confirm that ALL I need to do with a fresh Raspbian build is:-
wget https://dl.dropboxusercontent.com/u/802 ... 226.tar.gz
tar -zxvf 8188eu-20140226.tar.gz  
sudo install -p -m 644 8188eu.ko /lib/modules/3.10.32+/kernel/drivers/net/wireless
sudo depmod 3.10.32+
sudo reboot

As you probably gathered, I have no idea how this works and at one stage on a previous install, I mistakenly used the rtl8188eufw.bin file. I don't know if this updates the firmware on the dongle or just updates Rasbian - I did read somewhere that if the wrong firmware is used on the dongle, then it could be fatal, so I wondered if this might be the reason.

If you think the driver is OK, then I will have to look elsewhere.

Thanks in advance for any help you can give.

Hi woodside,

The instructions you've used to install the driver are all OK. Whether it works or not then depends on the configuration data required. For basic wifi use this would be done using file /etc/network/interfaces and may be file /etc/wpa_supplicant/wpa_supplicant.conf if you are using wpa_supplicant.

Regarding the firmware the version of driver I use does not need any external firmware file as it is included in the driver module so no need to worry about updating firmware. If you have loaded firmware rtl8188eufw.bin it will be ignored.

I have no experience using Piracast so I've no idea what you may need to do to get the driver working with it. The driver source file includes a load of documentation and includes one about Miracast so it may be useful to download it and have a look at that. The driver souce can be downloaded and unzipped using

Code: Select all

wget http://lazyzhu.com/file/RTL8188EUS_RTL8189ES_linux_v4.1.8_9499.20131104.zip
unzip RTL8188EUS_RTL8189ES_linux_v4.1.8_9499.20131104.zip
Hope that may be some help.

So the driver looks as though it is working correctly. I shall certainly look at the documentation, but whether I will understand it is another matter! Thank you so much for your prompt reply.

Is anybody getting a fail

with SSL on the download site? I'm issuing

Code: Select all

wget https://dl.dropboxusercontent.com/u/80256631/8188eu-20140307.tar.gz
as the command. It works with http though :-S My Mac on 10.6.8 Snow Leopard doesn't trust this certificate, yet my RPi does. Is there a trusted source online that I can update my certificates on my Mac? I've actually never done that, and perhaps they're really outdated. Still wondering though.

sudo apt-get update
sudo apt-get install ca-certificates
will fix it on your RPi.

Dear MrEngman,

All of us TL-WN725N V2 users appreciate the work you've done to get and keep our goofy WiFi adapter running. I don't know what we would do without you. Is there some way to get TL-WN725N V2 support added to the main Raspbian distribution so that you don't have to do all this work?

Hi twlare, thanks.

There is a version of the driver being included in development versions 3.12.y and 3.13.y but not the one I prefer. It is the driver being mangled by lwfinger and requires a separate firmware file which I find is totally unnecessary.

I did use the lwfinger driver for a while but then came across an unmodified driver from Realtek and I now use that as I find the other one has caused me various problems and using the separate firmware file is, I think. really unnecessary and over-complicated. The driver version I now use seems much more reliable.

This stuff I do now is similar to work I did with the driver for the EW-7811Un and other devices using the 8188cus before that was included in the available images. Keeps me occupied occasionally ;)

Hey MrEngman,

Thank god I stumbled upon your post after hours (or maybe minutes, is not that hard to find :D ) trying to make my wifi work. But after configuring it all and moving my pi to the living room to connect it to my TV it stopped working properly. While I have perfect signal strenght and low latency at 4m from the router, weird things happend when I move it behind a rather slim wall, at 4.1m. Those are the ping results to the router:

Code: Select all

Do you think it has something to do with the driver? My kernel version is 3.10.25+.

Re: (UPDATE) Drivers for TL-WN725N V2 - 3.6.11+ -> 3.10.33+

Hi otiumh,

The format you have used for /etc/network/interfaces means you do not need /etc/wpa_supplicant/wpa_supplicant.conf so that file will be ignored. The driver looks to be installed OK and is working as you see a list of networks.

I think there is a minor problem with file /etc/network/interfaces. I think it should be

Code: Select all

auto lo
iface lo inet loopback
iface eth0 inet dhcp

#WIFI

allow-hotplug wlan0
iface wlan0 inet dhcp

 wpa-ssid "MERLUZONET"
 wpa-psk "ernesto2716"
There should be NO = sign in lines wpa-ssid and wpa-psk.

Also it is not a good idea to show the network password. Now anyone can login to your wifi network. You should change the password.

Hopefully this will now get your wifi working.

I have seen similar behaviour. My access point is downstairs on one side of the house and the Pi is upstairs on the other side of the house. Ping results vary greatly depending on what I ping. e.g.

Code: Select all

If I change to a different access point, also downstairs but with one less wall between the Pi and access point the results are much more consistent.

Hi otiumh,

There doesn't seem to be any problem with the wifi data and information except the wifi does not connect.

This sort of problem is often because the wifi name or password is not correct. Are you sure you have the password set correctly?

What happens if you try the two commands

Code: Select all

sudo ifdown --force wlan0
sudo ifup --force wlan0
Try two or three times if it does not connect the first time.

Hi otiumh,

Your set up for /etc/network/interfaces appears OK and the driver is loaded OK and the wifi is working as the scan shows your network. Just trying to think what could stop your wifi not connecting as the network signal level is also very good.

The main items are making sure the network name and password are correct and does your router have DHCP enabled?

Does your router use MAC address filtering? If it does you need to add your wifi MAC address to the list of allowable devices in the router.


MrEngman

Edit: you could try resetting your router to see if that makes a difference.

"The main items are making sure the network name and password are correct and does your router have DHCP enabled? " Yes.

"Edit: you could try resetting your router to see if that makes a difference" Done.

"Does your router use MAC address filtering? If it does you need to add your wifi MAC address to the list of allowable devices in the router."----- This was the missing thing!!!!!!
Now the Raspi is updating thanks YOU!!! :D
I had the Raspi MAC in the list, but not the WiFi dongle MAC.


Thanks a lot for your help, your time and your patience.

That's good to hear your wifi is now operating OK.

I once had the same problem with the wifi MAC address :oops:

Glad to be able to help. Have fun with your Pi.

Download and install the driver, and firmware if required, with the following commands

wget https://dl.dropboxusercontent.com/u/80256631/8188eu-201xyyzz.tar.gz <--set data code for driver version above

# run following two commands only if using version 3.10.xx+, not required for 3.6.11+
cat README                                                               <--check README file for adding
sudo cp rtl8188eufw.bin /lib/firmware/rtlwifi                            <--firmware if not already installed
sudo install -p -m 644 8188eu.ko /lib/modules/$(uname -r)/kernel/drivers/net/wireless
sudo insmod /lib/modules/$(uname -r)/kernel/drivers/net/wireless/8188eu.ko
sudo depmod -a
Once the driver is loaded you will need to configure the network set up so the Pi will connect to your wifi network if it is not already done. There are some basic details on how to do that available here.

To help in installing or updating the driver @LaFambe has produced a very simple script available here which will automatically select and install the correct version of the driver for the version of Raspbian being used, and the firmware if necessary. I was quite impressed by it and it really does make life much simpler. To install the script look here.

Thank you very much, LaFambe.

I am trying to do this but do not have internet access on my Pi. So I am trying to put the driver firmware onto the SD card and access it from there to install. Hoping i can get some help, i have spent about 8 hours over the course of several days, but i am just learning all of this. @LaFambe @MrEngman @anyone who can help ;)

Hi undecided. I imagine you are able to download the driver elsewhere on a computer? Are you running Raspbian? Do you need the actual firmware or not? The firmware hasn't been necessary for many releases. Perhaps you are only referring to the driver and not the firmware?
Option 1: If you have GNU/Linux, you can mount the partitions on the RPi SD card with no problem and copy the files to the SD card directly to the correct location.
Option 2: If you have a different OS, perhaps the easiest is to boot the RPi with a USB flash attached the the USB port, loaded with the driver files. From there, you can mount the USB flash on the RPi and copy the files from the USB flash to the necessary locations of the RPi.
