How am I supposed to do it while my machine is fully hanged up? last test i did, gdm was killed, no X was running, not even caps lock was reacting to me. ctrl + alt + sysrq + R didnt help either.

No encryption or any other wireless security enabled. access point is 
used in only N mode. link quality is warring from 60-80(access point is 
in another room, below me ). Usually speeds i can notice on wireless 
interface are or 0 or 11 M a second.
Playing with any of the settings of the access point never gave any 
result really.

What else information are you seeking?
