Airport
 

I am using OS X 10.3.4 and connecting to the net using Airport 5.4 very unsuccessfully. I'm sure other people are having the same prob so are there any work arounds.
I'm using a PowerBook G4 512MB RAM 1Ghz.
I can get on most of the time but its a very unstable connection and it disconnects when ever it feels like and unfortunitely it messes up my connection to the internet and i have to re-start airport to get back on.
