How to Adjust the NOOK Color for an Adhoc WiFi

Get online with the Nook Color in restaurants, airports and stores.

The Nook Color, an e-reader that lets you flip through the pages of digital books and magazines, also allows you to connect to the Internet in places such as bookstores and coffee shops. The Nook Color only connects to Wi-Fi infrastructure networks; it normally cannot connect to ad hoc, or peer-to-peer, networks. The "wpa_supplicant" file, though, lets you run commands on a rooted Nook Color. Using the Nook Color command line, it is possible to force the device to connect to ad hoc networks.

Things You'll Need

• Rooted Nook Color
• USB cable

Instructions

1. Open your Internet browser and download the Easy USB ADB Installer from the Xda Developers website. Double-click the downloaded file to extract it to the computer. This file automatically installs drivers on the Nook Color so you do not need to do it manually.

2. Connect the Nook Color to the computer via USB cable. If Windows prompts you to use Windows Update, click "No." Allow the Nook Color to search for and install the drivers you downloaded.

3. Verify that the drivers installed properly. Click "Start" and type "cmd" in the search box. Press "Enter."

4. Type "cd\" and press "Enter." Type "cd android-sdk-windows\platform-tools." Press "Enter." Type "abd kill-server" and press "Enter." Type "abd devices." Press "Enter." If you correctly installed the drivers, your Nook Color's serial number appears.

5. Download and install the Battery Booster app from the AppBrain website. When you enable ad hoc on the Nook Color, the device may behave erratically. Battery Booster fixes this problem.

6. Launch Battery Booster on the Nook Color. Select "Battery Tweak." Select "Turn off WiFi" under "On Device Lock." Select "Turn on WiFi" under "On Device Unlock." Exit Battery Booster.

7. Download the "wpa_supplicant" file from the Xda Developers website. Extract the file to any folder on your computer.

8. Tap the Wi-Fi icon on the Nook Color. Tap "Airplane mode." This temporarily disables Wi-Fi.

9. Open the Android SDK folder on the Nook Color. Run ADB. Use the keyboard to type the following commands, pressing "Enter" after each line:
   $ adb shell mount -o remount rw /system
   $ adb push wpa_supplicant.infrastructure /system/bin
   $ adb push wpa_supplicant.adhoc /system/bin
   $ adb push adhoc /system/bin
   $ adb push infrastructure /system/bin
   $ adb shell chmod 755 /system/bin/wpa_supplicant.infrastructure
   $ adb shell chmod 755 /system/bin/wpa_supplicant.adhoc
   $ adb shell chmod 755 /system/bin/adhoc
   $ adb shell chmod 755 /system/bin/infrastructure
   $ adb shell mount -o remount,ro /dev/block/mmcblk0p5 /system
   $ adb shell adhoc

   These commands enable ad hoc Wi-Fi connections on the Nook Color.

10. Type the command "$adb shell." When you want to switch to ad hoc, type "su." Press "Enter" and type "adhoc." To switch back to infrastructure, type "infrastructure."

Tips & Warnings

• Rooting your Nook Color and installing these files voids your warranty. Do not attempt this process if you do not wish to void the warranty.

• Use caution when entering commands on the Nook Color. An improperly entered command can have negative effects, such as rendering the device inoperable.
