Hi all, I have a macbook with 10.5.4 (its my wifes' macbook so I gotta get this fixed for sanitys sake). It has strange wireless problems (all is fine on a wired connection). It will connect fine, never disconnects, but has about 50% packet loss and really strange ping time patterns. It hangs and then a bunch of packets will rush in all at once, with response times separated by one second eg, 2015 ms, 1915 ms 1815 ms etc etc I have several macbooks bought all at the same time, and when I take a super duper copy of one of my other books and boot the problem machine from it... it works FINE. Checked all wireless settings, I dont know what the difference is between the two software loads, I dont see any suspicious apps or anything (I have heard horror stories about something called coconut wifi). Can someone point me in the right direction to find out what software setting or app is causing this problem? I have done an archive and install and it didnt help.
