Ever since I got my new router, my old MacBook Pro, which I use to pay bills, has been disconnecting from the internet every time it goes to sleep. I have to go in and put the password in before it will connect to wi-fi. My iPhone and my newer MacBook Pro don't do this. Is there some preference or something that I can check that may be causing this? I haven't added any extensions or apps to this Mac since I got my newer Mac over 3 years ago.

Thanks.
