Guide me for buying the Ethernet shield

hai,

kduin:
you want to run a webserver on your arduino, which you can access from your laptop in your wifi, do you?

yes, you are right.

-> If not, you will have to buy a WiFly-Shield. (It connects with your router just like your Laptop or smartphone does)

i am already using wifly-shiled v2.0. My shiled doesnt works in infrastructure mode. i couldnt diagonise the problem. so i shifted to eternetshiled and wifi router. If you can please help me to work my wifly shield work in infrastructure mode.

What kind of project are you building?
