For the past few months I’ve been experiencing intermittent connection issues with my home internet. The internet would stop working completely, on every device in the house, for a period of 10-15 minutes a couple of times a day. After a few months of experiencing this, I decided to finally start investigating. It was this past weekend when I finally noticed that about a minute after I plugged my iPhone into a charger, any charger, the internet would quit working. I was able to consistently recreate the issue. If I unplugged the phone right away, the internet would come back right away.

I figured out it was due to iCloud’s automatic backup when plugged in and on a known wireless network. So, when the phone starts to backup, the internet connection dies for all other devices while the backup is taking place, or tries to take place. Most of the time, iCloud backups on my home network fail 1. I did some searching on the internet to see if others have had similar issues and found a couple of posts, but no real solution. For a few days I thought I had fixed it by resetting the network settings on the phone. It looked like the small, but annoying problem, was finally resolved. Or so I thought.

While working from home yesterday, the problem returned. Plugged in the phone and the internet would stop working. Unplug it and internet is back. I’m not sure what the exact problem is. Is it a problem with the modem? The router? iOS? Last night I decided to update to the latest iOS 9.3 beta to see if backups become more reliable. So far, it does not look good. The phone was not able to backup to iCloud overnight. I will have to test more at home tonight to see if my connection dies the next time it tries to backup. I’m not sure what else to try at this point, besides disabling iCloud backups, but I’m not giving up yet. Suggestions welcome 2.

EDIT: Check out my update on iCloud backups killing my internet connection. iOS10 seems to have fixed the issue.
