    Posted on Sun January 13, 2013

    The wires is not in fashion now. There is uncomfortable conducting wires in the apartment. It is not clear how to hold the wires in the garden. Yes, There is WiFi but the WiFi modules for Arduino is very expensive: https://ksdu.in/o/2l.

    About TP-LINK TL-WR702N:

    There is a low-cost and excellent performance router TP-LINK TL-WR702N which can be used with Arduino and Ethernet Shield.

    TL-WR702N is the smallest wireless router in the world and very easy to use. A traveler need simply plug a hotel room’s WAN cable into the port provided and enter a default password to instantly create a wireless hotspot in the room.

    The TL-WR702N is designed for use with tablets, smart phones, handheld game consoles and other portable electronic wireless devices. The device, which can be powered by an external power adapter or USB connection to a computer, can conveniently connect to the internet and share the connection around an average sized room at 150Mbps.The device’s tiny size makes it ideal for use on the road and is powerful enough to satisfy almost any basic wireless application requirement.

    See more information at the official TP-LINK website.

    Where to by TP-LINK TL-WR702N:

    You can find it in:

    Or look it in your local shops.

    The price is around $20. Plus the Arduino Ethernet shield w5100: http://ksdu.in/o/2o. The sum will be cheaper than price of one Arduino WiFi module.

    If you’ll take the enc28j60 module it will be even cheaper.
    See price for enc28j60: http://ksdu.in/o/2q.
    See the article: KSduino can connect your Arduino with Enc28j60.

    So if you’ll be use the Enc28j60 Ethernet Shield and the TP-LINK TL-WR702N Router the total WiFI cost will be about $25.

    How to use TP-LINK TL-WR702N:

    The WR702N Router is very easy to use. It has good documentation and intuitive Web interface. To get started:

    • You need to connect the router to your computer and configure it to Client Mode first. After this TP-LINK will be connect to your WiFi network.
    • Then you need to connect your Arduinu Ethernet Shield to TP-LINK Ethernet port and control Arduino as it is connected to the regular local network. You do not have to make any changes in the Arduino program to work with TP-LINK TL-WR702N Route.
    See the “Enc28J60 and Arduino (11)” article to detail instruction how to connect TP-LINK TL-WR702N.
