Hi guys, Just got my new rMBP and I absolutely love it. However, since installing the various updates the WiFi speed has become ridiculously slow. When I downloaded the updates I was getting 1.8mb/s (the maximum speed for our internet connection in the office). Since the update I struggle to get higher than 300kb/s from a source I know will max out the connection here. I've tried turning on/off the WiFi, forgetting the wireless network and rejoining, rebooting and shutting down completely. Has anyone else experienced an issue? Perhaps it's not exclusive to the retina MBP.
