Wires are so last summer! To the rescue is the WiShield, a plug-and-play Wi-Fi module for the Arduino from Asynclabs.
As the name suggests, the WiShield enables WiFi connectivity (802.11b) with an onboard PCB antenna from ZeroG Wireless. The board itself includes stack-through headers to allow access to unused pins and a 9-pin breakout header space for prototyping. The WiShield can create and join secured and unsecured networks, achieving up to 2 Mbps throughput speeds.

Pin Usage.
- SPI
- Slave select (SS) : Arduino pin 10 (port B, pin 2)
- Clock (SCK) : Arduino pin 13 (port B, pin 5)
- Master in, slave out (MISO) : Arduino pin 12 (port B, pin 4)
- Master out, slave in (MOSI) : Arduino pin 11 (port B, pin 3).
- Interrupt (Uses only one of the following, depending on jumper setting)
- INT0 : Arduino pin 2 (port D, pin 2)
- DIG8 : Arduino pin 8 (port B, pin 0)
- LED : Arduino pin 9 (port B, pin 1)
- To regain use of this pin, remove the LED jumper cap
