Haven't really found any good solutions to this. Every time my late 2013 Macbook pro goes to sleep, it disconnects wifi, which is a huge problem if I'm trying to download files. My old 2007 Macbook didn't do this when it went to sleep. I like that the computer goes to sleep when it's not being used because it saves battery, but the disconnecting from wifi is a huge issue. Anyone know how to get this to stop so that it stays connected to wifi.
