Here is my set up: 1 Mac powerpc 1 dell desktop running vista 1 macbook pro Airport express and Netgear 5 port fast ethernet switch I am using the airport express for the wireless for my mbp and iphone. However, since I dont have wireless cards on my my mac and PC, I need to use a LAN line. so right now I have a connection from the modem --> netgear hub --> airport express which give me wireless. But if I use ethernet cables to connect from the netgear hub to both of the powerpc and dell, then they don't get connections. I believe it has to be with the settings and Ip adresses. I'm not sure how to set that up. Currently my airport utility shows: Wireless mode: create a wireless network wpa/wpa2 personal using DHCP IP address: 24.30.x.x Sharing: share a public Ip address any help is appreciated. Hope I wasnt too confusing.
