Thanks, added a note to the tutorial - no idea what changed but we'll go thru and update our hostapd.zip as well when we have a chance. till then, compiling works best :)

hi, im trying to follow this step

Think I got it. Download and compile the latest drivers from http://www.realtek.com.tw/downloads/dow ... Down=false Choose the RTL8188CUS.

This is what I did:

cd /tmp
sudo wget "ftp://95.130.192.218/cn/wlan/RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.zip" (without the quotes)
sudo unzip RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.zip
cd RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911
cd wpa_supplicant_hostapd
sudo tar -xvf wpa_supplicant_hostapd-0.8_rtw_r7475.20130812.tar.gz
cd wpa_supplicant_hostapd-0.8_rtw_r7475.20130812
cd hostapd
sudo make
sudo make install

sudo mv hostapd /usr/sbin/hostapd
sudo chown root.root /usr/sbin/hostapd
sudo chmod 755 /usr/sbin/hostapd
sudo wget "ftp://95.130.192.218/cn/wlan/RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.zip" (without the quotes)(this line didnt work for me...there are people who say going to the site to download straight, but i dont know how to do that. any suggestions? thanks!

You should be able to proceed normally.

I don't understand how to get this link to work?
sudo wget "ftp://95.130.192.218/cn/wlan/RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.zip"
Seems like other people are getting it to work though? Any help would be much appreciated.
driver update instructions worked for me (except for the ftp and putting a sudo in front of the tar command)

You'd enter the string beginning with `sudo` from the command line on your RasPi. `wget` is a program that downloads files automatically.

I followed the manual down steps with success - I passed the "First test!" step (could see my iphone connect to the new ssid through the raspi terminal). However, there very next "Finishing up!" step yields "[FAIL] Starting advanced IEEE 802.11 management: hostapd failed!" when "sudo service hostapd start" is run. Any tips would be greatly appreciated (google has not turning anything up).

EDIT: found my error, I screwed up the DAEMON_CONF="/etc/hostapd/hostapd.conf" line in sudo nano /etc/default/hostapd

sk00t3r recipe still works except for where to initially download the zip..

http://www.realtek.com/downloads

Communications Network ICS ->
Wireless Lan ICs ->
WLAN NIC ->
Software ->
Check RTL8192C

Pick Linux Kernel 2.6.18~3.9 Download from one of Site [1,2,3,4...]

I got a file RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.zip which I transferred to the raspi then
just followed the previous instructions..

Final step is to copy the new hostapd to /usr/sbin

I've tried downloading and installing multiple versions of "hostapd" and no matter what I do I keep getting the following:

pi@raspberrypi ~ $ sudo /usr/sbin/hostapd /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf
drv->ifindex=3
l2_sock_recv==l2_sock_xmit=0x0x1365638
+rtl871x_sta_deauth_ops, ff:ff:ff:ff:ff:ff is deauth, reason=2
rtl871x_set_key_ops
rtl871x_set_key_ops
rtl871x_set_key_ops
rtl871x_set_key_ops
Using interface wlan0 with hwaddr 44:33:4c:74:3a:e8 and ssid 'Pi_AP'
rtl871x_set_wps_assoc_resp_ie
rtl871x_set_wps_beacon_ie
rtl871x_set_wps_probe_resp_ie
random: Only 17/20 bytes of strong random data available from /dev/random
random: Not enough entropy pool available for secure operations
WPA: Not enough entropy in random pool for secure operations - update keys later when the first station connects
rtl871x_set_key_ops
rtl871x_set_beacon_ops
rtl871x_set_hidden_ssid_ops
ioctl[RTL_IOCTL_HOSTAPD]: Invalid argument

Any suggestions would be greatly appreciated!

What OS/version are you using, and what do you have in /etc/hostapd/hostapd.conf?

I follow the OnionPi tutorial and I got the invalid argument problem.
I'm using a edimax wireless b/g/n nano usb adapter and I can get the driver.

When I try
sudo wget "ftp://95.130.192.218/cn/wlan/RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.zip"

I can't connect.

Do you have any idea?

Thank

The mirror in question might not have been working.

Check the Realtek downloads page for a working link: http://www.realtek.com.tw/Downloads/dow ... loads=true

You want the Linux version of the RTL8192CU driver (about halfway down the page).

Hi all,

my first post here :)

I had the same download problem, the link seems to be missing the "download user".

WebUser:r3iZ6vJI@ did the trick for me.

sudo wget ftp://WebUser:[email protected]/cn/wlan/RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.zip

Following sk00t3r's directions worked for the most part, however I think I am in the same boat as geordonv in that I can view the Pi_Ap and I'm no longer receiving HOSTAPD related Invalid argument error.. but it looks like DHCP is not working? Anyone else getting similar behavior? Anyone have tips or possible solutions?

Update: I believe this was related to the WPA Supplicant. I had to follow the 'extra' commands listed in the directions and pasted below:

Extra: Removing WPA-Supplicant
Depending on your distro, you may need to remove WPASupplicant. Do so by running this command:

Code: Select all

sudo mv /usr/share/dbus-1/system-services/fi.epitest.hostap.WPASupplicant.service ~/ 
and then rebooting (sudo reboot)[/color]

Posting from my new Wireless AP so I'm all good :) Thanks for the help

Worked for me. I needed to go through the RealTek site to find the downloads, as suggested by other users.

But once I had the download, the steps all worked perfectly. I have a functioning Raspberry Pi access point!
