Hello all, This is not a problem that I need help with; I'm just confused about something. My father installed Lion to his 2010 15" MBP, and said to me over the phone that he was suddenly able to get wireless internet reception in the upstairs of the house. I rejected this as nonsense for two reasons: number 1, there's never been workable reception upstairs for laptops (PC or Mac) since my father went wireless six years ago, and number 2, why the Hell would installing a new operating system improve wireless reception?! Surely that's a hardware/walls-and-floors issue...? But he's right. I've come home for a few weeks, and after installing Lion, I can now access the internet wirelessly from my old bedroom. When I was using Snow Leopard - both on this MBP, and an iMac that I've since sold - and Windows Vista - on a 2008 Sony Vaio - I couldn't. How has Lion managed to achieve this when Windows and previous iterations of OS X have not? Thanks in advance, DH.
