I have an arduino uno with ethernet built in. It's setup right now to turn the Christmas tree lights off/on. The router of course is upstairs and the tree is downstairs. I have a Dell Mini connected to the wifi and sharing the connection via the ethernet port to the Arduino. It works on the Mini and that's it. I can not figure out how to share the ip address with the whole wireless network.
Arduino <-> Ethernet (Dell Mini) <-> Wireless (Dell Mini) <-> Wireless Network
So what have you done on the mini to make it act as an ethernet bridge to allow bidirectional ethernet traffic thru it?
Well, I've tried. I know I am not doing right. But yes, that's the idea.
If the mini is a windows machine, you might try setting up internet connection sharing for the arduino.
No such luck. I'm visiting my parents. I've Ubuntu 11 installed. The bridge appears to be working. The problem is I can't get both sides of the bridge to talk.

Hmmm..., from my brief foray into linux in the 90's, "recompile the kernel".
Ha. Well, here are my settings...
Arduino:
IP: 192.168.1.177
Subnet: 255.255.255.0
Gateway: 192.168.1.121
Dell Mini (Ethernet side):
IP: 192.168.1.121
Subnet: 255.255.255.0
Dell Mini (Wireless side):
IP: 192.168.1.60
Subnet: 255.255.255.0
I can't online from the Mini either. I am running Ubuntu and firestarter to share the internet.
hate to be the one to just post a google link and no other help, but it's what I have to offer you. the answer you're looking for is likely here Google
what you want to do is set up a bridge between the wireless and ethernet. I believe they'll have to be on different subnets. like, if your existing network is 192.168.1.x, the arduino/ethernet side of the bridge could be 192.168.2.x then you'll be able to talk over that bridge between the 2 networks.
an alternate method you may not have thought of, plug the arduino into the laptop using usb. there are programs available to bridge a tcp/udp connection to the com port.
