Title:
no power management for Intel(R) PRO/Wireless 3945ABG/BG
Status in Linux:
In Progress
Status in linux package in Ubuntu:
Won't Fix
Bug description:
I have no power option for my wireless adapter. Especially when on AC this
gets very hot (nearly unusable).
In Windows I can lower transmission power which helps.
I am under the impression in earlier versions of Ubuntu I was able to do that
too (or through some tools).
Now it seems to be gone.
To my research it seems that the original drivers "ipw3945" have been
replaced by newer "iwl3945"?
Maybe thats the cause?
