I have 3 completely new boards straight out of the box from a batch of 8 and tried running a few sketches I wrote for basic ntp sync-ing. I know these sketches are working because they work with other older mkr1010's I have. Three out of the eight new boards aren't able to connect to the wifi network I'm trying to connect to.
I ran the scanNetworks example and the same three boards report no networks:
Any ideas what might be the problem? The network i am trying to connect to is my phone's wifi hotspot, and the phone is sitting on the same table as the boards.
