Slow Network / Internet Connection



I have a wirless network which supports an iMac G3 and an iMac G4, my internet connection is 512k broadband.

The G3 is running OS X 10.3.9 and the G4 is running 10.4.2

The problem I have is that the G4 is alot slower connecting to the internet then the G3. When I got the G4 it automatically detected the wirless connection and connected to the internet fine. Its just twice as slow to surf on it than the G3 and I dont know why. Can you help?

Im not sure what else I can tell you as my tech level isn't great.

Any help in this matter would be great

Kind Regards
