Query: Junk!

The software interface is awful, the instructions and customer support are bare minimum, and it causes my iBook g3 (10.4.11) to crash after about 1 hour of use. It also does not seem to have the ability to communicate a password to an encrypted network of the kind at my university, nor does it reliably detect fairly strong signals on a thoroughly wi-fi enabled campus. I find myself hunting for data line connections rather than using it. Of Macsense and of Apple (for not producing an affordable wifi option for those of us with "old" machines): A pox on both your houses!
