@pichlo thanks for the explanations i was just wondering about those anteenas in wap so buying one would be a waste of money rather i test it on a friends wap
one more question about those channels what are they for i.e when i check connection details it says connected to channel 1 and i googled a bit so just want to know how to change them on a n900 and weather they are responsible for speed /coverage
i disabled power savings in /settings/internet connections/n900 hotspot so thats it or there is something more to do
any advice on hotspot security to tighten it a bit more

so far i figured out quite a few things by myself next is ssh sheduled on sunday .. i am exited
