A keychain cannot be found to store "NETWORK." I just recently purchased a refurbished MacBook Air from Apple running Sierra. 

For the most part it is functioning just how I would expect it to, except for the following: for certain networks (it appears to be limited to just wpa2 personal networks. wpa2 enterprise with RADIUS authentication connects automatically just fine) it will not remember the pass. 

I leave the network, rejoin, and get prompted with the message:


  A keychain cannot be found to store "NETWORK."


It gives me an option to reset the keychain, which I would love to do (there are no custom CA/client certificates on here yet, just a stock certificate bank), but when it prompts me to put in my password, I can't type anything in the box. 

I have tried the solution listed here, but still get the same result.
A restart after applying system updates fixed this issue.
