Does anybody out there REALLY know if the new Airport Express will extend the range of an Airport (802.11b) base station, or does it only do this with an Airport Extreme (802.11g) base station? I've searched previous threads and see a lot of confusion about this. I've scoured Apple's web site and I see wording that could be construed either way, so I don't know what to conclude. I'm using an Airport equipped iBook with an Airport Base Station. Will I get any benefit from the 'bridge' function? Airtunes and wireless printing are probably enough for me to buy one, but I'd like to know whether I can also use it as a range extender. Thanks!
