We get a lot of questions about our F1 implementation ... here are some tips for those thinking of doing check-in via wireless kiosks ...
Don't get the Dell Optiplex SX280's ... these have no PCI slots meaning you have to use a USB wifi adapter. Get the GX280 small form factor so you can add a high end PCI wifi card.
Don't get the Dell 1450 USB Wifi adapters. They don't work with non-broadcast SSID's ... at least we haven't got them to work ... we're still waiting for final word back from Dell on this.
Any suggestions on a kick butt USB wifi adapter? Sadly Proxim doesn't make any USB ones :-(
