I've got a new Macbook Pro 17 early 2011. Whenver I put it in Stand By (closing the cover) the wireless fails to connect once restarted. I can get is restarted by turning the wireless off and back on. Is this an issue with the wireless settings or is this normal. A second issue I'm having is that I can't read a uSD card using a USB card reader. I've tried two different SD card readers, three different uSD to SD converters and three different uSD cards and none of them work.
