Alright i'm sure there is a thread someone where about this already but i have yet to find it. I got the free OS X Lion upgrade a couple days ago for buying my Mac within the Free upgrade time line. I currently own a early 2011 15 inch MBP quad i7 with 8GB Memory upgrade. Every time i resume from sleep i end up having to restart my computer to get the Wifi to work! As well my Mac seems to boot much slower after upgrading. Should i just go back to Snow Leopard?
