I had four zones earlier today, one on each of three laptops: A, B and C (and mutually visible) and the MC200 on all three laptops.

One laptop is now shut down (C). The other two (A and B) can only see two zones, that on one laptop (A) and the MC200. The other laptop (B) can see the MC200, the other laptop zone (A) but cannot see its own zone (B).

How can this be?

Everything is wireless except the wireless router to the MC200.

In the spirit of Spinaltap, I would like to confirm that I am not involved in the corrupt theft of a global sport.
