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%.
