Subject: ADHOC issue with WL12xx driver
Date: Wed, 26 Jun 2013 08:50:08 +0200 [thread overview]
Message-ID: <007501ce7239$65e40df0$31ac29d0$@macrix.pl> (raw)

Hi,
We are encountering serious AD-HOC problems:
. Commands are run successfully
. The network is theoretically created
. It is not visible for other devices and the DMESG show that an error
occurs and the firmware reboots
More info:
. The box running Linux is the VAR SOM OM44
. The operation system we are using is Ubuntu 12.04 LTS on the
3.4.0-1490-omap4 kernel.
. The processor is in the ARM architecture.
. WiFi card: Murata LBEH59XUHC.
. WiFi driver: wl12xx, wlcore firmware wl127x-fw-5-sr.bin with Rev
6.3.10.0.135.
. Network connection through the router is working. Network manager is
used to configure the connection.
. Ad-hoc mode connection is not working - the network is not visible
to other computers.
Commands used to configure the network in adhoc mode are as follows (wlan0
is the WiFi interface name):
1. Using iw:
. ifconfig wlan0 down
. iw wlan0 set type ibss
. ifconfig wlan0 up
. iw wlan0 ibss join ADHOC_TEST 2437
2. Using iwconfig
. ifconfig wlan0 down
. iwconfig wlan0 mode ad-hoc
. iwconfig wlan0 channel 6
. iwconfig wlan0 essid ADHOC_TEST
. ifconfig wlan0 up
Attached you will find the dmesg messages (dmesg.txt).
Using the latest backport of Compat Wireless backports-3.10-rc1-2 did not
help.
Testing with different WiFI dongles gave different results.
TP Link WN725N that uses the Realtek 8192cu driver and is based on the
RTL8188CUS-GR chipset is working correctly in AD-HOC mode.
Could you guide us in anyway in resolving this issue?
Pozdrawiam, Best Regards,
