Hello, Off late I have been faced with a very weird problem. I have a 13 inch white Macbook with Snow Leopard 10.6.6, and a desktop running Windows 7. I use wired internet on the desktop and wi-fe on the notebook. However, recently I noticed NONE of the Apple apps were working. Twitter for Mac refused to load up the timeline, App Store couldn't connect, and neither would Safari. All this while I could browse without any issues on Firefox. Somebody suggested I change the network location from Automatic to Home. I did that, and surely enough all the apps started working. However, I now lose connection every 2 minutes. Airport shows full signal strength but websites refuse to load and Adium signs out. I don't know why this started in the first place, but it would be awesome if any of you could help with a concrete solution. Thank you so much!
