I'm leery of public wi-fi too but I don't have an ethernet port so I don't have much choice anyway. There are ethernet jacks in my room (including one in the closet, inexplicably) but couldn't tell you if they're active.
At any rate, I'm currently connected over VPN to a client machine in Toronto and running reports like nobody's business. Speed is good, at least at 7:47pm local time.
From my hotel room, on wifi, from www.speedtest.net, I got these numbers:
63.46 Mbps download
9.53 Mbps upload
Hope that helps.
It seems to be good for now. We will see what it's like with 1500 FileMaker developers online at the same time tomorrow. But I don't remember having any major problems last year, if that helps.
9.3 by 9 right now
Yeah, I'm concerned about this too, but it's look like wifi is what we've got -- and as people have noted, it seems to be working reasonably well.
Make sure you're scheduling backups frequently. Very frequently.
I am talking to Shari about whether we can set up an ethernet router in Ask The Experts or another room.
