Everyone here seems very knowledgeable about Macs and wireless connectivity. So I have a question. Here is the scenario, Pismo 500 with internal airport, and lucent silver pcmcia card. I use kismac to find the network. It is MAC filtered, so i boot up the lucent silver using the sourceforge driver. Kismac will sniff with this card, I change the mac address to one on the the network. I am given an IP address, but can NOT connect to the internet, or others on the network. The only thing that works is physically removing the Airport card. Why is this, I thought they were independent of each other (airport and other cards)?? Is this happening with anyone else? Thanks for any help!
