Urgent suggestion required for wireless connection to arduino mega

Projects General Guidance
1

Hi all,

My current setup is: arduino mega connected to ethernet shield and lcd shield . Web page is hosted on the sd card of the ethernet shield. Ethernet shield is connected to the modem. On any PC that is connected wirelessly to the modem will be able to browse to the webpage that is hosted on the sd card.

My prof now wants the connection between the arduino and the modem to be wireless. how can I modify the current setup to achieve this?

Base unit: PC
Dispensing unit: arduino mega with pressure sensor, buzzer and lcd shield

Objective is to allow the base unit to connect wirelessly to multiple dispensing unit. Example, on base unit I can select which dispensing unit I need and schedule the alarm.

Please advise.

Do you have a wireless modem and have you tried the Wifi shield yet?

Is your Prof paying for your equipment ? (E.g the WiFi shield ?)

...R

I have not tried the WiFi shield yet. Is there any code difference between using the ethernet shield and WiFi shield.

I was hoping that there are no major changes to the code.

Are you connecting to a wireless modem or wireless router? You could get another wireless router, put it in the bridging mode, and then connect it to the arduino with ethernet shield. The arduino wifi shields are flakey in operation.
