Hi, On 3.7.9 iwlwifi for the Intel Centrino Ultimate-N 6300 works. On 3.8.latest, 3.9.latest and 3.10.latest it doesn't. Symptom: NetworkManager keeps on asking for a password. /var/log/messages: Aug 16 11:48:33 pcfvm kernel: [ 110.025291] wlan1: authenticate with 00:23:4e:33:8b:7d Aug 16 11:48:33 pcfvm NetworkManager[1196]: <info> (wlan1): supplicant connection state: disconnected -> associating Aug 16 11:48:33 pcfvm kernel: [ 110.036263] wlan1: send auth to 00:23:4e:33:8b:7d (try 1/3) Aug 16 11:48:33 pcfvm gnome-keyring-daemon[2053]: couldn't allocate secure memory to keep passwords and or keys from being written Aug 16 11:48:33 pcfvm kernel: [ 110.061782] wlan1: send auth to 00:23:4e:33:8b:7d (try 2/3) Aug 16 11:48:33 pcfvm kernel: [ 110.087120] wlan1: send auth to 00:23:4e:33:8b:7d (try 3/3) Aug 16 11:48:33 pcfvm kernel: [ 110.106771] wlan1: authentication with 00:23:4e:33:8b:7d timed out Aug 16 11:48:53 pcfvm NetworkManager[1196]: <info> (wlan1): supplicant connection state: associating -> disconnected Aug 16 11:48:53 pcfvm NetworkManager[1196]: <info> (wlan1): supplicant connection state: disconnected -> scanning Aug 16 11:48:56 pcfvm NetworkManager[1196]: <info> (wlan1): supplicant connection state: scanning -> associating Aug 16 11:48:56 pcfvm kernel: [ 132.643461] wlan1: authenticate with 00:23:4e:33:8b:7d Aug 16 11:48:56 pcfvm kernel: [ 132.658207] wlan1: send auth to 00:23:4e:33:8b:7d (try 1/3) Aug 16 11:48:56 pcfvm kernel: [ 132.685211] wlan1: send auth to 00:23:4e:33:8b:7d (try 2/3) Aug 16 11:48:56 pcfvm kernel: [ 132.709573] wlan1: send auth to 00:23:4e:33:8b:7d (try 3/3) Aug 16 11:48:56 pcfvm kernel: [ 132.733577] wlan1: authentication with 00:23:4e:33:8b:7d timed out An ath9k card in the same laptop works with kernel 3.10.7. kernel startup messages differ slightly: kernel: [...] Linux version 3.7.9 (works) kernel: [...] cfg80211: Calling CRDA to update world regulatory domain kernel: [...] Intel(R) Wireless WiFi driver for Linux, in-tree: kernel: [...] Copyright(c) 2003-2012 Intel Corporation kernel: [...] iwlwifi 0000:04:00.0: pci_resource_len = 0x00002000 kernel: [...] iwlwifi 0000:04:00.0: pci_resource_base = faab0000 kernel: [...] iwlwifi 0000:04:00.0: HW Revision ID = 0x35 kernel: [...] cfg80211: World regulatory domain updated: kernel: [...] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) kernel: [...] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) kernel: [...] cfg80211: (2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) kernel: [...] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) kernel: [...] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) kernel: [...] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) kernel: [...] iwlwifi 0000:04:00.0: loaded firmware version 9.221.4.1 build 25532 kernel: [...] iwldvm: Intel(R) Wireless WiFi Link AGN driver for Linux, in-tree: kernel: [...] iwldvm: Copyright(c) 2003-2012 Intel Corporation kernel: [...] iwlwifi 0000:04:00.0: CONFIG_IWLWIFI_DEBUG disabled kernel: [...] iwlwifi 0000:04:00.0: CONFIG_IWLWIFI_DEBUGFS enabled kernel: [...] iwlwifi 0000:04:00.0: CONFIG_IWLWIFI_DEVICE_TRACING disabled kernel: [...] iwlwifi 0000:04:00.0: CONFIG_IWLWIFI_DEVICE_TESTMODE enabled kernel: [...] iwlwifi 0000:04:00.0: CONFIG_IWLWIFI_P2P disabled kernel: [...] iwlwifi 0000:04:00.0: Detected Intel(R) Centrino(R) Ultimate-N 6300 AGN, REV=0x74 kernel: [...] iwlwifi 0000:04:00.0: L1 Enabled;
