Hello ,

 

I have setup a banana pi with armbian:

Linux bananapi 4.3.3-sunxi #3 SMP Mon Dec 28 11:27:16 CET 2015 armv7l GNU/Linux

I wuld like to setup a wifi access point from a rtl wifi dongle.

Realtek Semiconductor Corp. RTL8192CU 802.11n WLAN Adapter

First, I have tried with bananian and it was working perfectly. But I have also a tv adapter  not working with bananian, kernel 3.4 seems not support it.

 

With armbian vanilla, the tv adapter is supported but it seems to have an issue with the wifi dongle driver.

 

When I start hostapd-rt, I have the following errors:

drv->ifindex=5
l2_sock_recv==l2_sock_xmit=0x0x766b0
ioctl[SIOCSIWMODE]: Invalid argument
Could not set interface to mode(3)!
Could not set interface to master mode!
rtl871xdrv driver initialization failed.
wlan0: interface state UNINITIALIZED->DISABLED
wlan0: AP-DISABLED
hostapd_free_hapd_data: Interface wlan0 wasn't started

Do you have already ssen this issue?

I have seen that it is possible to build a driver provided by realtek. Do you think it culd solve it? I could try it but I need help how to do it.

I supose I need to follow this page: http://www.armbian.com/using-armbian-tools/and include the realtek driver?

 

Thank you

 

 

 

 

Have you try to use a normal hostapd ? (non realtek version)

 

You don't need to compile kernel if you are asking that ... 

I have also errors:

 

hostapd:

How to set wireless access point?

I confirm I have same issue if I follow the doc 

http://www.armbian.com/documentation/

OK. If you tried both options, than the the problem could be in wifi driver. This chipset is know to be troublesome ...

 

I have no information which driver is working well in kernel 4.3.3 ... I assume you use the driver supplied with kernel.

 

Blacklist the one from kernel and try those two:

 

https://github.com/dz0ny/rt8192cu

https://github.com/pvaret/rtl8192cu-fixes

Ok, for this step,  think I ned your help

 

I have an error when I try to compile https://github.com/dz0ny/rt8192cu.

root@bananapi:~/rt8192cu# make
make ARCH=arm CROSS_COMPILE= -C /lib/modules/4.3.3-sunxi/build M=/root/rt8192cu  modules

cd /usr/src/linux-headers-4.3.3-sunxi
make scripts

Than repeat the compilation.

Now hostapd succed to start but it is not possible to connect on the access point.

 

I have the folowing logs, if you have an idea:

Those drivers are buggy ... try setting up without WPA and make sure you use this config for interfaces:

 

https://github.com/igorpecovnik/lib/blob/master/config/interfaces.hostapd

 

Bridge mode is default, so your clients gets an IP from your router.

I have tried with bridge mode and without authentication.

My android fail to connect and I have no traces in syslog or hostapd output.

 

Does exist a way to try with a kernel 3.18 for example?

Try to shape hostap config and perhaps try other instructions/options/hostapd:

 

https://bogeskov.dk/UsbAccessPoint.html

https://www.google.si/search?q=rtl8192cu+raspberry+pi+access+point&oq=rtl8192cu+raspberry+pi

 

Hostapd itself also have a lot of options and this latest might simply not working with this device.

Ok I will try but same hostapd.conf with same dongle works with bananian and on a raspberry/raspbian

Try different hostapd version since driver is most likely the same (one from the kernel and the one you compiled).
