OSX Photo App causes Internet disconnects

This is my Feedback to Apple about the issue:

There is a problem with the Photo App when the iCloud Photo Library is checked in the preferences Pane:

This has consistently brought down my Internet connection causing the Globe Icon on the Airport Utility to be Orange instead of Green. The MacPro which is uploading is connected by LAN not WiFi. Users support pages reported issues with wifi.

Three visits from the ISP and replacing the cable modem 3 times and AE base station twice didn't solve the issue.

Turning on OS X (10.10.3) PHOTO APP connection to the iCloud Photo Library consistently reproduced the problem and turning it off resolved it. This is True for both my MacPro MacBookPro.

Photo library 22K photos, 307 video clips (89GB)

iCloud plan=200 GB

Please validate and correct as soon as possible

Photos uploading causes my internet to disconnect, therefore my photos can't get uploaded and in fact all when that happens I can't do a thing on the internet at all on any of my devices: iPhones, iPads, appleTVs, and 3 apple computers. And this happens instantly the moment Photos starts uploading. If you have read my posts it was by here chance and deductive reasoning that I stumbled on the reason the internet was disconnecting. Hours by multiple ISP technicians were spent for 6 days trying to trouble shoot this problem until I stumbled on it this afternoon. This is not about disconnecting from apple or encryption as you mentioned.

Did your internet stay connected though? Were you able to access it while Photos was setup to connect to iCloud Photo? I ended up uploading my pictures manually, it is cumbersome but it works.

That is very much like what has happened to me. This is what I mean by MANUAL:

1. Disconnect Photos app from iCloud

2. Drag (or export) the photos you want to upload to the cloud into a folder on your computer.

3. Log on to your iCloud account using Safari and and the iCloud Photos web app

4. Click on the Upload tab, it will pint to your finder, select the with the photos you want upload and then "Choose" the photos

5. it will start uploading without straining your connection. I do about 100 photos at a time.

After you have Uploaded your photos. Reopen Photos again (using the option key) but this time with any empty Photos Library and set it as the "default system library" and reconnect it to iCloud. It will download/sync to your computer all the photos that you have uploaded, This time there should be no issues with internet connections. This cumbersome but it works for me.
