It seems that Ubuntu 11.10, specifically Network Manager, does not change at all the frequency of the wlan-signal.
Ok, if it does change somehow, then: Which factors does the Network Manager take into account?
Does it take into account the humidity of the air?
A few years ago the radio towers were made a lot more efficient by taking into an account the humidity of the air. It would be trivial to have humidity control measurers in my laptop either internally or preferably as an external body. It would definitely improve my internet connection's strength, since by increasing the signal frequency in the high humidity -conditions the frequency would be increased to the level that is allowed by the regional laws.
Which files do control the frequency of the given emitters?
