OBSOLETE as of 12 November 2015 update that fixes the authentification loop and increases speed:

Finnaly, I think I have my BPi-R1 with a stable WiFi and no freezing whatsoever

I used the latest distro packages and it still froze on occasion

I managed to pin it down to the wpa encryption used by hostapd

Here is my config:

### Wireless network name ###
interface=wlan0
### Set your bridge name ###
bridge=br0

driver=rtl871xdrv
device_name=RTL8192CU

# The RTL8192CU provides simple legacy and 20MHz/40MHz co-existence mechanisms to ensure backward and network compatibility. Maximum PHY data rate up to 144.4Mbps using 20MHz bandwidth, 300Mbps using 40MHz bandwidth

I read on this page that the hardware crypto on the rtl8192cu might not work correctly:

http://forum.lemaker.org/thread-15515-1-1.html

Also issues due to encryption happened (on the same rtl8192cu chip) to this guy also:

http://www.linuxquestions.org/questions/linux-networking-3/realtek-8192cu-driver-problem-with-ccmp-encryption-4175506363/

 

The WiFi speed used is 54Mbps but at least it is stable and my router doesn't freeze anymore

Back with an update

I have the latest armbian updates and compiled original relatek drivers, hostapd and wpa_supplicant for RTL8192CU

Just tested the connection by downloading about 5.31GB of data in 15 minutes (about 7MB/sec) on wifi

Also I made some tests with speedtest.net:

 

WiFi

 

Ethernet

 

My internet line is a 100Mbit/sec

No freeze or authentification loops happened since I compiled the three realtek sources ( http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PFid=48&Level=5&Conn=4&ProdID=277&DownTypeID=3&GetDown=false&Downloads=true#2772 )

I compiled sources on 09.11.2015

Can you be more specific about your configuration? Please share with us your configs and/or make "how to" from fresh armibian image, thanks

I'm on last armbian version

 

I first compiled the hostapd, wpa_supplicant and driver with 'make ARCH=arm' as Igor told me

Replace '/usr/sbin/hostapd-rt', '/usr/sbin/hostapd_cli-rt', wherever it is 'wpa_supplicant' and '/lib/modules/3.4.109-banana/kernel/drivers/net/wireless/rtl8192cu/8192cu.ko' with the ones compiled.

NOTE: with new armbian upgrades these files are going to be replaced

 

This is the new hostapd configuration '/etc/hostapd.conf-rt'

As you see I had to comment the 'noscan' line

Can you update Tido´s basic router setup manual? I can't reproduce your result Maybe I missed something...

Hi,

 

I have recently found this discussion. I am having the same issue. Once in a while banana pi r1 just freezes.

I would like to find if it could be the same issue as described here.

 

I have downloaded and installed Armbian in February 2016. It is legacy one - "Linux lamobo-r1 3.4.110-sun7i #10 SMP PREEMPT Wed Feb 10 20:03:33 CET 2016 armv7l GNU/Linux"

 

I would like to ask if I could have the issue mentioned here or if some patches were already applied to legacy Armbian.

 

I am really happy with the setup. Only problem I need to solve is freezing. If the system would work reliably, it would be perfect router.

 

Thanks

R1 has some design problems, problems are mostly power related so make sure you fixed that. How? - check other R1 related topics. Further - lowering RAM speed init in u-boot and not using crappy on board wifi.

Hello,

 

I have the same issue with Bananian. Can you tell me if I still have to compile original relatek drivers, hostapd and wpa_supplicant for RTL8192CU if I download an actual armbian? Or is this integrated there?

I can only speak for: http://mirror.igorpecovnik.com/Armbian_4.2_Lamobo-r1_Debian_wheezy_3.4.108.zip and it works out of the box.
But the latest version of 3.4 Kernel is .110  or  .111 so give it a try.

... and try also those alternative drivers:
