if it's wifi that's causing the trouble, the usual causes are:
is the complaint the hotel ROOM wireless? or the meeting-room?
meeting net, a-secure and a. really bad during the night, but still
bouncing up until 08:30 when i turned laptop off to participate in
breakfast.
and conjecturbation as to what the problem was is amusing at best. i
asked for actual diagnosis from whover is running the net.
I am noticing far worse performance and reliability with IPv6 as opposed
to IPv4. For a good 10 minutes until just now there was *no* IPv6 routing
even to the first hop, but IPv4 was still "working." Now things are
merely slow, not broken.
I also got bounced a few times from -secure and -a and when I got back I
couldn't get an address (IPv4 or IPv6) for some time.
Conjecturbation: They're using an old proteon router and someone is
exhausting its arp and ndp caches.
