Connecting and Testing with a WiFi
Connection
On the back side of the Galileo is a Mini PCI Express slot that can hold a WiFi
module so that your project can connect to the Internet wirelessly.
In order to use a WiFi card, you must boot Galileo off of a MicroSD card that
has a more complete version of Linux than runs on Galileo by default. This is
because the drivers needed to work with WiFi Mini PCI Express cards do not
fit into Galileo's on-board flash memory. For information on how to load a
MicroSD card with Linux and have Galileo boot off of it, see
Appendix D
.
To test your wireless connection:
1. With the board disconnected from USB and power, insert your WiFi
module on the bottom of the board (
Figure 6-2
).
2. Be sure to attach an antenna if your WiFi module requires it.
3. Connect your Galileo to power.
