The cause looks to be related to RFKILL. Initially when I booted all I got in dmesg was: cfg80211: Using static regulatory domain info cfg80211: Regulatory domain: EU (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) (2402000 KHz - 2482000 KHz @ 40000 KHz), (600 mBi, 2000 mBm) (5170000 KHz - 5190000 KHz @ 40000 KHz), (600 mBi, 2300 mBm) (5190000 KHz - 5210000 KHz @ 40000 KHz), (600 mBi, 2300 mBm) (5210000 KHz - 5230000 KHz @ 40000 KHz), (600 mBi, 2300 mBm) (5230000 KHz - 5330000 KHz @ 40000 KHz), (600 mBi, 2000 mBm) (5490000 KHz - 5710000 KHz @ 40000 KHz), (600 mBi, 3000 mBm) cfg80211: Calling CRDA for country: EU iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, 1.3.27kd iwlagn: Copyright(c) 2003-2009 Intel Corporation iwlagn 0000:10:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 iwlagn 0000:10:00.0: setting latency timer to 64 iwlagn 0000:10:00.0: Detected Intel Wireless WiFi Link 4965AGN REV=0x4 iwlagn 0000:10:00.0: Tunable channels: 11 802.11bg, 13 802.11a channels iwlagn 0000:10:00.0: irq 27 for MSI/MSI-X phy0: Selected rate control algorithm 'iwl-agn-rs' Normally I'd expect to see the following after that (from .30): iwlagn 0000:10:00.0: firmware: requesting iwlwifi-4965-2.ucode iwlagn 0000:10:00.0: loaded firmware version 228.57.2.23 Registered led device: iwl-phy0::radio Registered led device: iwl-phy0::assoc Registered led device: iwl-phy0::RX Registered led device: iwl-phy0::TX wlan0: authenticate with AP 00:14:c1:38:e5:15 wlan0: authenticated wlan0: associate with AP 00:14:c1:38:e5:15 wlan0: RX AssocResp from 00:14:c1:38:e5:15 (capab=0x411 status=0 aid=1) wlan0: associated So it did not even try to load the firmware... After the boot completed I tried unloading and reloading iwlagn, and then I suddenly got: iwlagn 0000:10:00.0: PCI INT A disabled cfg80211: Using static regulatory domain info cfg80211: Regulatory domain: EU (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) (2402000 KHz - 2482000 KHz @ 40000 KHz), (600 mBi, 2000 mBm) (5170000 KHz - 5190000 KHz @ 40000 KHz), (600 mBi, 2300 mBm) (5190000 KHz - 5210000 KHz @ 40000 KHz), (600 mBi, 2300 mBm) (5210000 KHz - 5230000 KHz @ 40000 KHz), (600 mBi, 2300 mBm) (5230000 KHz - 5330000 KHz @ 40000 KHz), (600 mBi, 2000 mBm) (5490000 KHz - 5710000 KHz @ 40000 KHz), (600 mBi, 3000 mBm) cfg80211: Calling CRDA for country: EU iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, 1.3.27kd iwlagn: Copyright(c) 2003-2009 Intel Corporation iwlagn 0000:10:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 iwlagn 0000:10:00.0: setting latency timer to 64 iwlagn 0000:10:00.0: Detected Intel Wireless WiFi Link 4965AGN REV=0x4 iwlagn 0000:10:00.0: Tunable channels: 11 802.11bg, 13 802.11a channels iwlagn 0000:10:00.0: irq 27 for MSI/MSI-X phy0: Selected rate control algorithm 'iwl-agn-rs' iwlagn 0000:10:00.0: firmware: requesting iwlwifi-4965-2.ucode iwlagn 0000:10:00.0: loaded firmware version 228.57.2.23 iwlagn 0000:10:00.0: Radio disabled by HW RF Kill switch I then noticed that the wireless led on the notbook was indeed off, but it was totally unresponsive to any attempts to turn it on.

After rebooting into .30 wireless worked again.
