I created a new adhoc network in Ubuntu using the NetworkManager applet, with SSID "UbuntuAdhoc", band "automatic", BSSID (blank) and no security. Under IPV4 settings I set it to "Shared to other computers". Unfortunately I get this when trying to load the module with debug: $ sudo modprobe -v iwlagn debug=0x43fff insmod /lib/modules/2.6.38-020638rc7-generic/kernel/drivers/net/wireless/iwlwifi/iwlagn.ko 11n_disable=1 debug=0x43fff FATAL: Error inserting iwlagn (/lib/modules/2.6.38-020638rc7-generic/kernel/drivers/net/wireless/iwlwifi/iwlagn.ko): Unknown symbol in module, or unknown parameter (see dmesg) [ 447.551540] iwlagn: Unknown parameter `debug' $ sudo modprobe -v iwlagn insmod /lib/modules/2.6.38-020638rc7-generic/kernel/drivers/net/wireless/iwlwifi/iwlagn.ko 11n_disable=1 [ 501.570685] iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, in-tree: [ 501.570688] iwlagn: Copyright(c) 2003-2010 Intel Corporation [ 501.570760] iwlagn 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 [ 501.570772] iwlagn 0000:03:00.0: setting latency timer to 64 [ 501.570809] iwlagn 0000:03:00.0: Detected Intel(R) Centrino(R) Advanced-N 6200 AGN, REV=0x74 [ 501.580698] iwlagn 0000:03:00.0: device EEPROM VER=0x436, CALIB=0x6 [ 501.580703] iwlagn 0000:03:00.0: Device SKU: 0Xb [ 501.580739] iwlagn 0000:03:00.0: Tunable channels: 13 802.11bg, 24 802.11a channels [ 501.580836] iwlagn 0000:03:00.0: irq 44 for MSI/MSI-X [ 501.583936] iwlagn 0000:03:00.0: loaded firmware version 9.221.4.1 build 25532 [ 501.584236] cfg80211: Ignoring regulatory request Set by core since the driver uses its own custom regulatory domain [ 501.584392] ieee80211 phy0: Selected rate control algorithm 'iwl-agn-rs' Here I create the adhoc network in network manager: [ 536.509700] ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 536.858139] cfg80211: Found new beacon on frequency: 2472 MHz (Ch 13) on phy0 [ 536.947735] cfg80211: Found new beacon on frequency: 5180 MHz (Ch 36) on phy0 [ 537.041220] cfg80211: Found new beacon on frequency: 5200 MHz (Ch 40) on phy0 [ 537.079114] cfg80211: Found new beacon on frequency: 5220 MHz (Ch 44) on phy0 [ 537.175392] cfg80211: Found new beacon on frequency: 5240 MHz (Ch 48) on phy0 [ 538.973811] cfg80211: Found new beacon on frequency: 5745 MHz (Ch 149) on phy0 [ 539.203969] cfg80211: Found new beacon on frequency: 5785 MHz (Ch 157) on phy0 [ 539.289182] cfg80211: Found new beacon on frequency: 5805 MHz (Ch 161) on phy0 [ 571.156548] ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 599.156798] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready [ 599.161234] wlan0: Trigger new scan to find an IBSS to join [ 604.131831] wlan0: Trigger new scan to find an IBSS to join [ 607.103522] wlan0: Creating new IBSS network, BSSID 42:dd:e6:af:fb:19 [ 607.104488] iwlagn 0000:03:00.0: Unable to find TIM Element in beacon [ 607.105407] iwlagn 0000:03:00.0: Unable to find TIM Element in beacon [ 608.501173] wlan0: Trigger new scan to find an IBSS to join [ 609.190883] wlan0: no IPv6 routers present [ 613.397068] wlan0: Trigger new scan to find an IBSS to join [ 616.303044] wlan0: Creating new IBSS network, BSSID ae:eb:cb:59:18:ec [ 616.313716] iwlagn 0000:03:00.0: Unable to find TIM Element in beacon [ 616.314529] iwlagn 0000:03:00.0: Unable to find TIM Element in beacon [ 617.681034] wlan0: Trigger new scan to find an IBSS to join [ 622.736806] wlan0: Trigger new scan to find an IBSS to join [ 625.708399] wlan0: Creating new IBSS network, BSSID 46:b6:a0:1b:c4:7f [ 625.761157] iwlagn 0000:03:00.0: Unable to find TIM Element in beacon [ 625.762035] iwlagn 0000:03:00.0: Unable to find TIM Element in beacon [ 627.438640] iwlagn 0000:03:00.0: Error sending REPLY_RXON_TIMING: time out after 500ms.
