After upgrading from Nexus 5 to Nexus 5X, I am unable to connect to my company's wifi. The credentials I provide are correct, and sometimes I do manage to connect, but that lasts only several seconds to minutes.
The wifi screen shows the wifi with "Saved", which then goes through "Connecting", "Authenticating" and back to "Saved".
How can I debug this and see what is happening? Is there a log I can investigate? All other wifis have no problems so far.
