Update to the problem. While trying to isolate what was going on in /var/log/messages. The problem is related to sleep/restart. Here is the output if I am connected and cycle the wifi switch.
I bring the device up with ifconfig wlan0 up: Oct 12 22:22:06 venus kernel: [13493.849640] iwl3945 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 Oct 12 22:22:06 venus kernel: [13493.914589] Registered led device: iwl-phy0:radio Oct 12 22:22:06 venus kernel: [13493.914639] Registered led device: iwl-phy0:assoc Oct 12 22:22:06 venus kernel: [13493.914680] Registered led device: iwl-phy0:RX Oct 12 22:22:06 venus kernel: [13493.914722] Registered led device: iwl-phy0:TX Oct 12 22:22:06 venus kernel: [13493.955866] ADDRCONF(NETDEV_UP): wlan0: link is not ready It connects: Oct 12 22:22:37 venus kernel: [13525.182816] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready Cycle the wifi switch (ifconfig still reports that wlan0 is up): Oct 12 22:23:52 venus kernel: [13600.399285] iwl3945: Radio Frequency Kill Switch is On: Oct 12 22:23:52 venus kernel: [13600.399289] Kill switch must be turned off for wireless networking to work.
