Mikael and all attendees,

The TKIP problem is not the only problem we're dealing with. If we knew
more about exactly what problem you were having I might be able to tell you
the status of any related problem.

We are tracking a problem with excessive broadcast traffic triggered by
scans of our network from the outside. We're actively mitigating that
issue. On occasion it's caused broadcast packets to be dropped before being
delivered to wireless clients. This has affected the ability to use IPv6 on
occasion.

I will note that there also seem to be scans of our network coming from our
clients. Please note that the triggered broadcasts from ARPs, for example,
can affect the performance of everyone. We provide an open network for
everyone to use, and we encourage all of you to use it. However, please be
aware that some actions may hurt performance for others. We ask you to be
respectful of all users.

Thanks
Chris.
