Message: "Unable to authenticate against security settings" when using wifi
I have gotten this error before, but I don't think much after I updated to 10.3.1.
Basically any regular network I connect to will randomly stop connecting and when I attempt to connect, it will refuse to connecting saying, "unable to authenticate against security settings."
Lately I've been getting it on my network in my school, but sometimes I even get the problem on my home wifi. I don't know off-hand what's causing it. I don't modify the advanced settings, except to modify the DNS lookup address when Rogers decides to be stupid (Rogers DNS lookup often screws up, so the fix is to change the DNS to Google's DNS 8.8.8.8 and 8.8.4.4).
Has anyone else had this issue? Is there a fix?
