Hi,
My requirement is send serial data(using ATMEGA) via Ethernet and receive it from PC to data base. i do google the topic and found few details. Serial Device server, serial to Ethernet converter, serial to wifi module

it is better if can send data via wireless LAN. which is already installed. please help to start my project.

From your post it is not clear if you want to use the Ethernet cable to send serial data or if you want to use the Ethernet data services as per OSI model. Serial data is not compatible directly with the Ethernet data model

Take a look to this link so you clarify.

You can receive serial data through many more forms in the computer than Ethernet. You can use RS232 RS485 or even a USB FTDI.

You're not the first to want to do such things. Have you visited the Arduino sites to see how others have solved this problem. There are a number of solutions.

Here's one I was working on the weekend with:

TP-LINK TL WR3040 wireless router with openwrt firmware and a usb to serial dongle. $59 for the wifi unit and $3 for the usb serial dongle. Battery powered to boot.

We just finished a robotic project that has a Netgear wireless router installed. I designed my own CPU board with 3.3V outputs from one of the uarts (ATMega 2560) and fed the RX/TX lines into a netburner SBL2EX serial to Ethernet convertor. It works flawlessly - can communicate wirelessly with my PC over TCP/IP or UDP with no problems. No special protocol stacks required. The Netburner runs about $30.00.
