    In the last few days when I open up a browser it says its not connected to the internet. I can't ping google for example but my wireless connection is fine and the Airport Base Station has a green light.

    When I open Safari it complains I'm not on the internet so I click the Network Diagnostics button which pops up, shows 2 red icons showing I'm not on the internet, asks me what wireless connection I want and then all of a sudden the icons go green and says my settings have changed and I'm good to go.

    Why would it suddenly start doing this? The only thing I can think of is the fact I did a software update.

    Have you tried turning Airport off and then on?

    Sys Prefs > Network > Advanced > TCP/IP > Configure: using DHCP, see if that works. If you are connected but have no connectivity it usually means you don't have your IP properly set up.

    I've tried turning Airport on & off and it works for a bit but when the iMac wakes from sleep I have to start again.

    DHCP is what its setup to do
