That is an interesting thought.
Ok, a little update. I did reinstall Open Transport just for good measure. I also unplugged an old airport expresss I use in the basement (yes, another one of those Old Mac caves!!) as an extender for plugging in ethernet. Now when I try to connect to the wifi I am having a lot more success. I do need the Berg connector plugged in though for enough juice. I am going to button it up, take into a much better signal area and put it to the true test.
Things are still a bit buggy and while I have both user name and password in the ini file, it does not automatically log in. I have to select the network from the wifi control panel. Maybe that is how it is supposed to work.
Bottom line, I think it is signal strength and the concept of the usb cable helping may be true. Or maybe just a little more power.
thanks all for the hints.
