Gentlepeople,
We just wanted to give everyone an update on the state of the wireless
network here at the Hilton. As most people noticed, we had severe
problems involving APs going away starting right around 9am when the
first meetings began. We identified and worked around the problem and
the APs have been up and reasonably solid since mid-morning.
However, despite the APs staying up, we continued to see problems,
particularly on the 3rd floor. Common symptoms were:
- Long delays before receiving DHCP responses
- Long first hop round trip times
- Loss on the first hop (in the wireless domain)
- Receiving a DHCP address, but still not having the ability to
contact the default router
Moving forward, we've made several configuration changes which should
help matters, and we believe that most of the problems have been
resolved. Please (gently) let us know if you're still seeing major
problems. The 2.4G band (802.11b/g) is still pretty congested and has
some inherent issues in a situation like IETF meetings, so if you have
the option to use 802.11a, we'd suggest you do so.
As always, any trouble reports or questions can be directed at
ietf-62(_at_)ietf(_dot_)org(_dot_)
Again, our apologies for the frustration and annoyance this is
causing. Believe us, we want to get this to work just as much, if not
more, than you all do!
- Jim
