Ok so whenever I boot my system i will connect to the network, but not be able to use the internet. I have to go through a song and dance of turning the AirPort off and on(several times usually) before it has a ful working connection. It only does this after a restart or normal bootup, not coming out of sleep. Any ideas? I am new to Mac so that maybe part of it. I am using a Netgear router and WPA encryption if that helps. Thanks in advance!
