A friend of mine have the same 11n AP and for them it also behaves
pretty shitty for him (Windows even worse then Linux...).

I don't know if it is worth to continue to debug with this this 
particular 11n AP.

I had a good performance during LinuxCon which indicates that it is
really only my home AP. What I could do is to test with 11n APs at my
workplace and see if the it is really only my home 11n AP.
