My 2010 15" MBP has constant Wifi dropouts, sometimes minutes at a time. Sometimes I have to reconnect. Yet it gets 4 bars. My MacBook never had these problems. It's generally slower, too. It's now useless for online video like Hulu. Anyone else seeing this? I wonder whether it's hardware (e.g. they moved the antenna, and/or because of the metal case) or software/drivers? I'm going to submit feedback after input from ya'll.
