Cheapest way to connect to WiFi

What is the cheapest way to connect to WiFi?

The Arduino wifi shield costs a lot, which really puzzles me.

Probably the cheapest way to connect to a WiFi network with Arduino (compatible) hardware is to use a Seeeduino Ethernet and a TPlink WiFi router (TL-WR702N). You get both together for under 50€.

Actually cheaper is to get a standard Arduino and then use a USB/TTL breakout to connect the TPLink (i prefer the WR703N) to the Arduino Serial port

True, but then you have to program the TPLink too (and you have to change it's firmware), it's not sufficient to make a sketch on the Arduino.

Huh ?? The TPLink comes with OpenWRT pre installed and ready to go.

You can find Thousands of basic examples of a linux serial monitor/capture daemon

OK, excuse me, I didn't know that, I expected a proprietary firmware pre-installed. But you still have to make some code if you want to have web access to your Arduino variables, that's what I wanted to express with my post.

Yes you are right there - although depending on what you wanted to do it could be really simple or really complex.
