HP wireless print server

[rgn22]

I have an HP 100 wireless print server for Mac which has been functioning properly for a quite a while. Recently the 3rd LED has been blinking red, and my laptop cannot see the printer anymore. I tried switching out the wireless card, but that did not solve the problem. I can connect via USB and print just fine. I can't find any support documents for this product.

I have a G4 iBook running Tiger.

Any ideas?
