USB WiFi Adapter Driver Help

abcd567 · August 3, 2016, 4:16pm

I purchased a usb wifi adapter RTL8192 chip, 300Mbps.
Canadian $10.47 + Free Shipping, Requires Driver Installation (CD Provided),

When I tried to install driver, error
Need help.

This is what happened:

Is this for a RPi?

Did you try just plugging it in and seeing if the built-in drivers worked?

Normally you just have to change two files:

/etc/network/interfaces


source-directory /etc/network/interfaces.d

auto lo
iface lo inet loopback
iface eth0 inet manual

allow-hotplug wlan0
iface wlan0 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

and /etc/wpa_supplicant/wpa_supplicant.conf


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

network={
	ssid="myssid"
	psk="secret"
	key_mgmt=WPA-PSK
	scan_ssid=1
}

scan_ssid is set to 1 if you have a hidden SSID, 0 if published.

Yes, initially I added my wifi passwd & id in file “wpa_supplicant.conf”, then pluged in and watched, then rebooted, but it wont pickup.

I have purchased another one (Canadian $2.55+Free shipping) which is Plug-n-Play and started working out of the box. No driver installation required, but its range is not good.

Thanks for guidance. I will try your method on my 2nd Pi.
On my Pi 1, I have solved the problem by following method:

SOLVED!

I solved it by installing driver as described on this page:

raspberrypi.org/forums/view … p?t=148389

$ uname -a
Linux pi1 4.4.13+ #894 Mon Jun 13 12:43:26 BST 2016 armv6l GNU/Linux

$ sudo wget dl.dropboxusercontent.com/u/80256631/8192eu-4.4.13-894.tar.gz

$ sudo tar xzf 8192eu-4.4.13-894.tar.gz

$ dir
8192eu-4.4.13-894.tar.gz 8192eu.conf 8192eu.ko install.sh

$ sudo ./install.sh
…
…
$sudo reboot

Note:
Before trying to install driver from CD, I have opened file /etc/wpa_supplicant/wpa_supplicant.conf and added ssid & psk, as shown below.



$  sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

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

#Added the 4 lines below
network={
        ssid="xxxxxxxxxxx"
        psk="yyyyyyyyyyyy"
}

On my Pi2, I checked the 2 files “/etc/network/interfaces” and " /etc/wpa_supplicant/wpa_supplicant.conf".
Both files are exactly like you have posted, and the file wpa_supplicant.conf has correct wifi ssid & passwd, but the Wifi adapter does not pick up. Tried reboot, no success. I then tried the same method as for Pi1 (B+), but that site does not have driver for my Pi2 (Model2). I have now posted on that site, a request for driver for the Pi Model 2 (4.1.19-v7+ #858).

I take the opposite approach of buying dongles that are known to work out of the box. Out of tree vendor drivers are a pain to set up and the quality is usually a bit suspect.

abcd567 · August 3, 2016, 7:32pm

I have now learned the lesson, but the hard way.

Anyway it is surprising that the cheaper one (can $2.55) is plug n play and worked out of the box (no driver installation required), while the other one 4 times the cost (can $ 10.47) requires driver installation, and the driver provided by seller on a CD does not even get installed!

Make sure to include:


key_mgmt=WPA-PSK

Inside the wpa_supplicant.conf network brackets.

Jranderson777 · August 4, 2016, 2:33am

I’ve felt the same pain too. I’m with OBJ. Dongles that need a custom driver installed are a total PITA. Not only do you have to get it working the first time, but when you upgrade the operating system you have to go through the driver compile/install all over again.

abcd567 · August 4, 2016, 3:13am

I did not know it will require a driver when I ordered it (the RTL8929EU 300mbps). There was no mention of driver CD. Only when i received it, I found it has a CD.

The other cheaper model 150 mbps proved to be plug-n-play. It worked out of the box, no driver installation. The cheap one has limited range about 20 to 25 feet only.

Actually I dont need wifi adapters. It was just an experiment out of curiosity. My entire installation, including antennas is indoor, and I have wired network available at locations of all the 3 RPi s.

edgy · August 4, 2016, 3:37am

My RPi 3 of course has built-in, but the RPi 2 I bought a “Realtek Semiconductor Corp. RTL8191SU” (that’s what is says when I do a lsusb). It’s labeled IOGear GWU625 and the PX sells them for $20. I have 3 of them on my network computers, as my router is out in the garage. They seem to work just fine. Kind of slow finding the network on reboot (20 seconds or so).

On my piaware Pi (the RPi 2) I connect it to some heliax to the antenna up about 20 feet, and connect to the internet via the wireless. Then I run the wired network to my desktop in link-local dhcp mode (169.254.x.x network). That way I don’t burn-up the wifi network with my port 30003 data to the database feed.

My Linux knowledge is in bits and pieces, not a proper systematic learning like going through a tutorial or a book.
Just out of curiosity, want to know what are linux-headers & Makefile Rules?
Can I install these by apt-get or some other way?
Please see below what I got when I tried to install driver from the .tar.gz file from installation CD:

make[1]: Entering directory ‘/usr/src/linux-headers-4.4.13+’
Makefile:606: arch/armv6l/Makefile: No such file or directory
make[1]: *** No rule to make target ‘arch/armv6l/Makefile’. Stop.
