AirPort always Dropping Connection
MacBook Pro , WiFi Problem
“MacBook keeps losing Airport connection” – some discussion here – http://discussions.apple.com/message.jspa?messageID=8837719
Problem statement : “/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -s” restarting at least every 3-5 seconds … Which means dropping WiFi connection – and , as a result lost of internet connection .

Where 192.168.215.1 – my ASUS WL-500G Premium v2 …
I made some investigation about these problem .
First I just remove executable attribute from “/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport” . These REALY was
helpful a lot ! Surprise – stopping scanning , and connection now REALY stable – no drops at all !

Next step . Try to understand – what f…g happens ?! Try this small script :
vintage-c2d:~ ilyxa$ ps -ef |grep air | grep -v grep | awk '{print "ps -f -p "$3}' | sh<br /> vintage-c2d:~ ilyxa$ ps -ef |grep air | grep -v grep | awk '{print "ps -f -p "$3}' | sh<br /> UID PID PPID C STIME TTY TIME CMD<br /> 0 1750 14 0 0:00.00 ?? 0:00.01 /bin/sh /Applications/Utilities/Wi2Geo/getwifi<br />
RUN THIS MORE THAT ONCE !!! IT’S VERY IMPORTANT .
My problem was some kind of wireless utility from Russian Navigation Network …
Check this , it can be really simple and fast solution and NOT a hardware problem … Just erroneous application design … WOW !!!
PS : when u clicking at AirPort icon – and see SCANNING every time – THIS IS NOT a problem . This kind of scanning do not use cli framework , IMHO …
