Q: I just upgraded to Sierra and I can no longer download files larger than about 35 megs.  Never had a problem till the upgrade.  Am I overlooking something?  Thanks for any help.

Thanks for the help.  It is NOT a wireless issue.  I am connected to my router by cable not wifi.  It seem to happen when the computer goes into screen saver mode. Hope this clears up the mis-communication on my part and you can come up with another idea.  Thanks again.

   Thanks for the response Becky.  I will read the articles tomorrow after work. 

     I tried an experiment yesterday.  I started to download a file while I was using the computer for other things and it downloaded fine.  When I tried the same thing on the same file before going to bed it stopped 37 mb into the file, so it seems to definitely a problem with the screen saver (or whatever it is called on a mac).  Let me know if there is anything that would do this.  Thanks again.

Not so crazy.   The settings were putting the computer to sleep after 15 min.  I will try tonight and see if it is the cure.

Thanks.

yep...that was the problem.  Thanks for the insight.  Appreciate the help.
