Not really, I think Leopard's amazing BUT...my internet has always been faffing about since i clean installed Leopard, lingering on the "contacting so & so" bit in the status bar. Safari often tells me I'm not connected to the internet, yet at the same time I would be downloading a file. Recently the airport signal on the in the menu bar has been displaying half strength when I can actually see my Netgear wireless router on the other side of the room. It can't be the routers fault because my ATV, friends PC, iBook and even my Wii (you heard) works fine. I've tried restarting everything, moving the router/modem to another phone socket, and even playing around with the MTU. Has anyone got any suggestions?
