Enable connection to Ad-Hoc WiFi networks

• thanks to cicada, johnopsec, and silivrenion

By default, the Nook Color will not connect to ad-hoc wifi networks. This will allow you to connect to those ad-hoc wifi networks, such as another android phone hotspot or computer.

What you need

• adb access
• The new wpa_supplicant file from http://forum.xda-developers.com/attachment.php?attachmentid=461427&d=1292048964
• A program that disables/enables wifi when the screen is shut off/on. Recommended is http://www.appbrain.com/app/setting-profiles-full/com.probeez.profiles

The Process

• Unzip the file to a work directory on your computer.
• Turn OFF WiFi on the Nook Color
• Run the following commands:

$ 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 adhoc

• At this point you could stop, however you will find erratic behavior when sleeping from wifi. Stability will be greatly improved if you follow the below.

• Install an application that will turn WiFi on/off if the screen is turned on/off. The rest of this guide will assume you used Setting Profiles Full.

• In Setting Profiles, create two profiles, one for Wifi Off and one for Wifi On.

• Create two rules, one to activate Wifi Off when Screen turns off, and another activating Wifi On when the screen turns on.

Result

After this is done, you can switch back and forth between the original and the adhoc enabled wpa_supplicant by starting a shell on the Nook Color and running the following commands:

To switch to adhoc mode:

su
adhoc

To switch to infrastructure mode:

su
infrastructure

You shouldn't have to switch between profiles if you installed an application to turn off/on wifi automatically.
