Follow these step-by-step instructions to set up an ad hoc WiFi network. A WiFi network in ad hoc (or peer) mode allows two or more devices to communicate with each other directly instead of through a central wireless router or access point.
Difficulty: Average
Time Required: < 1 hour
Here's How:
- For each computer (device), determine whether the device has WiFi capability.
- Purchase and install WiFi network adapter hardware in devices that do not possess WiFi capability.
- Configure each WiFi network adapter to run in ad hoc mode.
- Test each device's network connection.
Tips:
- When using ad hoc mode, be aware of several security issues and performance limitations of ad hoc WiFi networks.
- The most common sources of trouble in ad hoc mode networking are incorrect configuration and insufficient signal strength. Ensure your devices are located close enough to each other, and ensure configuration settings are made identically on each device.
