Password error
I have an iMac G4 and I’ve tried to connect it to my router (Zyxel from Telefonica, Spain) but without any success. Other devices (PC & iPhone) do connect correctly, so now I have an Airport Express that right after connecting it both to power and router (via cable), my imac recognizes it and I’m able to surf the Internet. However, one LED shows that it is not configured, in fact I have been unable to protect the wifi with a password. It shows the following message: “Password Error. It seems that the selected file is not a valid firmware image for an AirPort base station". Why is this error due? Can someone help me through the configuration? Please take into account that this is the first time I use a Mac. Thanks
