I have a Note 5 and, as many people have now learned, there is a high failure rate for the Marshmallow update on these phones. Testing done in Asia revealed the bugs. They are well documented as affecting wifi access and battery-life in particular, The problems are so common and widespread that Samsung announced the development of a fix for the Note 5 update to be rolled out at a later date. Yet, Verizon continues to push this update! Look at these forums as well as others all over the internet. Marshmallow is causing all manner of problems on the Note 5. I don't want the update on my phone and now it has begun the process of nagging me.
Verizon-- pull back the update!
