Is there a different Wifi driver to try or do I have the 'best' one already? I have a stock installation of Ubuntu Natty (11.04) on a HP Laptop with this Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

lsmod | grep iwl shows:

iwl3945               126017  0 
iwlcore               148964  1 iwl3945
mac80211              257001  2 iwl3945,iwlcore
cfg80211              156212  3 iwl3945,iwlcore,mac80211

I've read about a driver from Intel called iwlwifi. Is this what I have? Is there a different driver to try? My wifi works fine, but I'm trying to see if there is anyway to lower it's power consumption. powertop shows iwl3945 always at #2 with ~30%.

  • FYI, I was able to lower my power consumption with: sudo iwconfig wlan0 txpower 5dBm Since this driver does not allow setting the power timeout. YMMV.

The iwl3945 module is a driver from the iwlwifi project. The other drivers from the project are iwl4965 and iwlagn, which target different generations of the Intel Wifi hardware.

There was an older driver available for your card by the name ipw3945, but Ubuntu hasn't shipped with a kernel that featured the driver for some time (it was superseded by the newer iwlwifi drivers).
