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. michael
