OK, I have an Airport card in my eMac. My eMac sees it OK. I have an iMac connected to a wireless router. My eMac sees the router, but when I type in the password to connect I get a cannot establish connection error. THERE IS AN ERROR JOINING THE AIRPORT NETWORK " xxxxxxxxxxxxxx " (xxxxxxx being the name of my router. Just realised that even though the eMac sees the router it is getting no signal, all lines in airport icon in Menu Bar are grey and not black as when there is a signal of some strength.
