Here is my report.
I downgraded to version 3.203.
Does not work.
Got the same message that says.
No Internet Connection! Find new networks to reconnect.
So I upgraded back to version 3.211
This time , I chose 5 GHz wifi
And , bingo , it seems to work.
I have not done anything different this time.
Except , this time , I chose 5 GHz instead of 2.4GHz.
So , it looks like 2.4 GHz wifi will fail to work with Beryl at my school.
I wonder why I did not choose 5 GHz before and tried.
I guess I was not as curious as I thought I was.
Or not as good at troubleshooting as I thought I was.
Bottomline:
Try 5GHz and see if it works for you.
