I just tried the software base station feature of OS 10.2 using my Ti 500 and my G-4 450 tower. Very cool.... easy to set up and it works well for short ranges. It only seems to carry the signal 30' - 40', basically the rooms surrounding the G-4 tower, but much past that the signal fades out. I realize that the Airport card isn't nearly as strong as a base station, but I was wondering..... Has anyone else used this? Is that about the maximum range for the set up? Any tricks to increase the range? Thanks, Richie Burr Dover, DE
