Unfortunately it's not all roses on my HP nc2400. Sleep works, and works well, however a couple of times wireless (iwl3945) hasn't returned after sleep. I *think* this is after an extended period of sleep (a few hours), rather than 20 minutes.
rmmodding iwl3945, iwlwifi_mac80211 and cfg80211 and re modprobing didn't help. dmesg reported that the RF kill switch was off, when it wasn't. Turning it off and back on didn't help. It's a soft-switch with two leds (front and button), the switch appeared to work. ifconfig -a didn't show the eth1 interface (or wlan0), iwconfig reported no interfaces with wireless extensions. It seems the nic goes into a deep sleep and doesn't recover, shown from this snippet of dmesg: [ 566.057603] iwl3945: Detected Intel PRO/Wireless 3945ABG Network Connection [ 566.134658] iwl3945: Radio Frequency Kill Switch is On: [ 566.134665] Kill switch must be turned off for wireless networking to work.
