I have been using my Mac Book Pro (15" Lion, latest version) for coming on a year. I used to open the cover, it would search for my wifi, and in 15 seconds I could start web surfing.
Suddenly, in the few weeks though, it is doing something strange...
It still finds the wifi connection in a few seconds (the Wifi icon shows all dark), but now it takes an extra 90 seconds plus until I can actually load anything in a browser.
I noticed that Skype connects after about 90 seconds, then a few seconds later Safari allows me to start loading web pages, and then a few seconds later Chrome will let me start loading web pages.
Very nerve wracking! Any suggestions for diagnosing this or speeding this back up again?
