Hi I need the nedtuino mini to connect to the Wifi to call a webApi on internet.

 

How can I achieve that?

 

What is the cheapest module that I can use with the mini to connect to internet?

 

Thanks

It's not reliable yet, but you can use the WRL-3000 hardware and the cc3000.codeplex.com driver.  But, if you want something reliable, it probably won't be that cheap.  There are a few vendors (like bluegiga, murata, and digi) that make wifi chips with UART interfaces that will be more reliable, but you'll have to write a library to control it from C#.

You might look at these cheap serial to WiFi modules,

Some practical usage,

These are pretty easy to use on the Mini COM1 port. The Picaxe doesn't have string handling capabilities so forming message strings should
be a snap on the Mini. I have a HLK-RM04, but have never hooked it up. The TLG10UA03 looks to be more user friendly.

 

EDIT:
Some of those supplier links showed a RS232 serial interface. I would look for TTL serial for COM1.
