Ok! Nice (in a way, anyway) to hear that this is happening to someone else. The problem is that it works fine with my PB G3. My boss also has airport at home where it works fine, just like slapdash explained.

I really wonder about interference though. Since it works flawlessly with my PB G3.

It is a bit annoying that there is no simple solution to this. I've tried to zap the pram and then it worked for a while. Maybe until he switched to his home network and back to the office. That is a possibility.

If I want to change the frequency, how do I do?

Very much thank you
