My friend has a G4 powerbook with OS10 and has purchased an Airport card. (I'm a pc man.. so Mac knowledge a bit thin...) It came from an appple reseller in france, just an antistatic bag with card and no software. I plugged it into the slot on the side... and expected something to happen... but nothing. I found the airport stuff in networking and internet connect.. I can see an airport hex address (my pc speak MAC address) associated with the card but it does not pick up my linksys wireless router. I've got four PCs working happily.. no WEP, no MAC address filtering.. it's open.. totally. I've no way of knowing if the card is working ok. all the MAC networking stuff is configured for DHCP.. so is my router... stuck... can anyone help...
