Q: iCloud photos library stuck in a never ending upload that slows and stops my entire network.

Last month I successfully upgraded to El Capitan. Since then, after choosing to automatically upload and store my entire photo library to the cloud, the upload process has caused a great deal of problems. First of all, I had to leave the laptop on day and night and connected to the internet in order to complete the upload. It almost completely uploaded (with several modem reboots because the massive data upload caused connectivity crashes) but then I had a trip planned and had to shut the process down. I tried to start it up again when I got to my destination but it looked to have started the process all over again (see below where the progress bar is at the very beginning again when prior to that it was almost all the way to the end) and shut down my poor host's network several times AND it ate up all of my CPU activity slowing down and even halting every other laptop activity. Finally, I had to quit the process altogether for the remainder of my visit. In fact, I had to turn wifi off on my laptop because the process continued in the background even when I had the Photos app turned off. When I returned home, I researched the problem and learned to repair the library by holding down the Command and Option buttons when I turned on the Photos program. Once again, the process started all over again and this time, it showed a completely different number of items to upload (there was less than 25,000 items prior to this upload now it shows more than 26,000).

Finally, I took it to the Apple Genius Bar, hoping for a quick solution. He, likewise, repaired the library as well as some other permissions using Apple Diagnostics. Everything seemed to be working fine again but the process had to start all over again for some reason and he told me connect the laptop to the modem using a cable and leave it on overnight until the process completed. I did that. The first night, I was pleased. It looked like 25% of the process had already completed. At that rate, it would only take another 4 days. He told me that once it completed, it would never have to do it again. HOWEVER, after the second night of leaving it overnight directly connected to the modem, I checked it this morning and it looks to have started ALL OVER AGAIN FROM THE BEGINNING! It still hangs up my entire network. I can't watch Apple TV, nor use my iPad for work or my iPhone to access maps and such. Currently, it seems to be a never ending nightmare of uploading and messing up my network (and notice that there are now over 28,000 items).

This is intolerable. I can't live in this never ending loop of photos uploading, crashing my network, and slowing down my programs. I understand this is not an isolated problem for me. So, has anyone found a simple solution other than using onedrive or flickr or some other photo syncing program?
