i've tried to reset the airport by removing the preferred network, and removing keychain etc. i've also tried resetting the airport preferences in the system configuration folder. nothing seems to work, and as you can tell, my connection drops about every minute or so. only thing i can do is turn it off and on. so annoying

any help would be much appreciated.
