Since the release of Android 2.2 (Eclair) the Android OS has had the ability to turn your phone into a hotspot. Because different manufacturers style the OS differently so exact instructions might be a little different for you (for the record I wrote these instructions using a Nexus One with CyanogenMod 7.1).
Always check with your carrier as different companies handle data limits and charges for tethering differently.
- Go into your Settings
- Choose Wireless & Networks
- Choose Tethering & Portable Hotspot
- Choose Portable Wi-Fi Hotspot Settings
- Choose Configure Wi-Fi Hotspot
- Name your hotspot, choose WPA2 PSK as your security and enter a password, then Save
- Tap the box next to Portable Wi-Fi Hotspot
- Turn on you Kindle Fire and go to the Wi-Fi settings.
- Select your hotspot by it’s name and enter your password.
- You’re connected!
