I have iCloud set to automatically download my photo stream to my laptop. About 10% or 20% of the time, the photos automatically download as long as both the iPhone and laptop are connected to the Internet. The rest of the time, the photos do not download, even when both the iPhone and laptop are connected to the Internet (the iPhone always has Internet; the laptop usually has Internet). I cannot identify any type of pattern as to why the photos sometimes but do not always download. Any guidance on this would be appreciated.
