I restarted and as mentioned by another user the connection icon was showing my connection was established but it was not. I searched but, now I can not find that thread
I have the same problem on 2 different hardwares after installing the new 2011-6 ISO
However, the old one, 2010-12 , fully updated did not have that problem. It was fine , day after day.
I noticed, with the new ISO, that if I reboot once or twice, the connection works.
Beats me, but
for now, it's OK
The other thing that works is, when the icon shows a connection ( which is not working ), I disconnect, then connect again. Then it also works.
This is not new to me as I had this problem for over a year , before 2010-12 came out.
I am not in a hurry to start messing around, as I have many other things going on.
So, this information is just that....information !
