Package: linux-2.6 Version: 3.2.17-1 Severity: normal Tags: upstream Dear Debian folks, the `brcmsmac` [1] module does not support IBSS [2] needed to create ad-hoc networks [3][4][5]. This prevents for example using shared WLAN connections from smart phones. `/var/log/syslog` contains the following messages. ieee80211 phy0: brcms_ops_bss_info_changed: qos enabled: false (implement) ieee80211 phy0: brcmsmac: brcms_ops_bss_info_changed: disassociated ieee80211 phy0: brcms_ops_bss_info_changed: arp filtering: enabled false, count 1 wpa_supplicant[2209]: nl80211: Failed to set interface into IBSS mode wpa_supplicant[2209]: Association request to the driver failed 1. Would it be better to use the module `b43` by default which is supposed to support all modes [3]? 2. If support for IBSS in `brcmsmac` is implemented, could that be backported to Linux 3.2? For interested people, Broadcom’s proprietary `wl` driver supports IBSS too. The WLAN controller in this system is identified by `lspci` as 08:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01) and Broadcom’s proprietary driver `wl` identifies the following. wlan0: Broadcom BCM4727 802.11 Hybrid Wireless Controller 5.100.82.112 Thanks, Paul [1] http://wiki.debian.org/brcm80211 [2] https://en.wikipedia.org/wiki/Independent_Basic_Service_Set#Independent_basic_service_set_.28IBSS.29 [3] http://linuxwireless.org/en/users/Drivers/b43#Comparison_of_recent_drivers [4] http://linuxwireless.org/en/users/Drivers/ [5] http://wireless.kernel.org/en/users/Drivers/brcm80211
