I've had several macs before and I know a lot of the laptops suffer from annoying wifi connectivity issues (if you're in a crowded place, you'll often have to mess with the settings in order for you to get a working IP address assigned, and often when you wake them from sleep they take seconds to connect). However, a new issue I've noticed with the rMBP is when you wake it up, it'll take an extra long time to connect to your network, and a few times it's required me to turn off Wifi and turn it back on to get any connection working. Has anyone else noticed this on their rMBP?
