Oggin, yep 'g' standard router in base station mode. Remembers five configurations so you could use one slot as relay rather than base. This means you can use it on a home or commercial wifi system to act as a repeater to extend the range of your regular base station. Our centrino tablet PC is on the aircraft so haven't tried linking it yet - we like to keep it out of our sight until we have to do perf calculations
Daysleeper: The iBooks seem to be able to suck a signal from just about nowhere which isn't fair. Therefore we had our 17 inch Powerbook man roaming - the metal casing makes reception far more problematic. No problems for adjacent rooms in a modern concrete palace but, as you'd suspect, the rebarred concrete floors prevented reception above and below the room where the Airport was plugged in.
However, our remaining PC stalwart isn't on duty at the moment but we're looking forward to his return as he has an outstanding USB external antenna ( a Linksys product I think) which might do the trick on floor to floor reception.
Finally, and as we're talking comms for RoadWarriors, firewalls. Prime PPRuNe audience don't have the luxury of a known and trusted hardware firewall much of the time so here's a recommendation for the Mac contingent. You're working on a unix software base which the masters of the command line can configure for protection in incredible detail. There's a utility out there now which will give you a very usable point and click version of what they can manage. Search on 'BrickHouse' and give it a trial. My lot have found it very useful indeed while out on the road.
Regards to all,
Rob
