I've recently started to notice wireless failures -- after being connected for a few minutes, the connection dies. Other devices on the same network continue to work. 'iw dev wlan0 disconnect' will fix it. I'm not at all sure, but I think this is a 3.2 regression. My kernel is 3.2.2-1.fc16.x86_64. My device reports as: [ 9.971111] iwlwifi 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 [ 9.971121] iwlwifi 0000:03:00.0: setting latency timer to 64 [ 9.971155] iwlwifi 0000:03:00.0: pci_resource_len = 0x00002000 [ 9.971156] iwlwifi 0000:03:00.0: pci_resource_base = ffffc900050dc000 [ 9.971158] iwlwifi 0000:03:00.0: HW Revision ID = 0x35 [ 9.971256] iwlwifi 0000:03:00.0: irq 50 for MSI/MSI-X [ 9.971307] iwlwifi 0000:03:00.0: CONFIG_IWLWIFI_DEBUG disabled [ 9.971309] iwlwifi 0000:03:00.0: CONFIG_IWLWIFI_DEBUGFS disabled [ 9.971310] iwlwifi 0000:03:00.0: CONFIG_IWLWIFI_DEVICE_TRACING disabled [ 9.971312] iwlwifi 0000:03:00.0: CONFIG_IWLWIFI_DEVICE_TESTMODE disabled [ 9.971313] iwlwifi 0000:03:00.0: CONFIG_IWLWIFI_P2P disabled [ 9.971319] iwlwifi 0000:03:00.0: Detected Intel(R) Centrino(R) Ultimate-N 6300 AGN, REV=0x74 [ 9.971373] iwlwifi 0000:03:00.0: L1 Disabled; Enabling L0S [ 9.981946] iwlwifi 0000:03:00.0: device EEPROM VER=0x436, CALIB=0x6 [ 9.981949] iwlwifi 0000:03:00.0: Device SKU: 0x1F0 [ 9.981951] iwlwifi 0000:03:00.0: Valid Tx ant: 0x7, Valid Rx ant: 0x7 [ 9.981982] iwlwifi 0000:03:00.0: Tunable channels: 13 802.11bg, 24 802.11a channels [ 10.119812] iwlwifi 0000:03:00.0: loaded firmware version 9.221.4.1 build 25532 and the failure and subsequent forced reconnect looks like: [ 659.272849] cfg80211: Calling CRDA for country: US [ 659.280937] cfg80211: Regulatory domain changed to country: US [ 659.280945] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [ 659.280952] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2700 mBm) [ 659.280957] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 1700 mBm) [ 659.280962] cfg80211: (5250000 KHz - 5330000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 659.280968] cfg80211: (5490000 KHz - 5600000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 659.280973] cfg80211: (5650000 KHz - 5710000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 659.280977] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 3000 mBm) [ 659.372989] wlan0: moving STA xx:xx:xx:xx:xx:xx to state 3 [ 682.786577] iwlwifi 0000:03:00.0: Tx aggregation enabled on ra = xx:xx:xx:xx:xx:xx tid = 0 [ 686.067870] iwlwifi 0000:03:00.0: Queue 12 stuck for 2000 ms.
