Just wanted to chime in that mine dropped as well. I read the thread in the announcement forum. Somehow I always seem to be in the 5% or whatever small number of users that is affected by these issues.

As usual, a reboot of my 502 corrected the problem.

My question is, why didn't it re-register by itself? And also why does the adapter always think it's registered when it obviously (as evidenced from the Devices vPanel page) is not?
