Hi,
I updated and rebooted my Raspberry Pi 2B+ this morning, and now WiFi refuses to connect. The adapter is recognized and working, but when it tries to connect it just associates with the access point for a few seconds then disconnects with "Reason: 1=UNSPECIFIED". It was working fine for days before I rebooted it this morning, and it's never had this problem after rebooting before. Any ideas what could be causing it?
