Comment 0 for bug 830539

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To my research it seems that the original drivers "ipw3945" have been replaced by newer "iwl3945"?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?

How can I switch to "ipw3945" to see if it solves the problem.
Or how can I solve the issue otherwise?
