It's not you!
Neither your routers, repeaters or access points.
It clearly is an annoying blocking bug in that Lumia 650!!!
I'd liked to hear or read about this before I decided last week to buy one after the price had dropped.
Did anyone try if the Windows Insider fast ring preview version (build 14385.0) solves the issue?
