Hi, I'm trying to figure out how to fix WPA-secured IBSS; which appears to be silently falling back to creating unsecured IBSS networks at the kernel level (or IBSS/RSN really, if need be, as it seems to react pretty much just the same, although I understand it's not supported by all devices). That bug has been initially reported at https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/905748. This has been tested on around version 3.2.11 (Ubuntu 3.2.0-18.29-generic 3.2.9); and observed on iwlwifi, iwl496, ath9k and rt2800pci. Wpasupplicant 0.7.3-6 appears to be creating the IBSS network just fine, but running into an issue with the nl80211 layer: mtrudel@gaea ~/Documents % sudo wpa_supplicant -dd -cwpa-adhoc.conf -iwlan0 -Dnl80211 Initializing interface 'wlan0' conf 'wpa-adhoc.conf' driver 'nl80211' ctrl_interface 'N/A' bridge 'N/A' Configuration file 'wpa-adhoc.conf' -> '/home/mtrudel/Documents/wpa-adhoc.conf' Reading configuration file '/home/mtrudel/Documents/wpa-adhoc.conf' ap_scan=2 Line: 2 -
