Great news everyone! </farnsworth>

ADHOC Wifi Support for Nook Color (stock)!

[EDIT] There appears to be an issue reconnecting when wifi sleeps and comes back on. Researching a permanent fix, in the meantime go to settings -> Wireless and toggle wifi off/on to correct it

This fix will allow you to connect to ADHOC wireless networks ( such as to a laptop or with wifi-tether on an android phone )

Like most other fixes, this requires your nook to be rooted and usb adb working, please follow the guides here and/or at the nook dev wiki first!:


HOWTO enable ADHOC tethering:

1. Download and unzip the attached zip file below, this should give you a wpa_supplicant-adhocfix file


3. Make a backup of your current wpa_supplicant:
adb pull /system/bin/wpa_supplicant  wpa_supplicant.backup

4. Remount the /system partition RW:
adb shell mount -o remount,rw /dev/block/mmcblk0p5 /system
5. Push the new wpa_supplicant:
adb push wpa_supplicant.adhocfix /system/bin/wpa_supplicant
6. Fix permissions:
adb shell chmod 755 /system/bin/wpa_supplicant
7. Remount the /system partition RO:
adb shell mount -o remount,ro /dev/block/mmcblk0p5 /system
8. Enable WIFI on your NC, you should now be able to see ADHOC networks in the list! ( they'll be displayed with a (*) prefix )

[edit] Credit where credit's due, this was taken from a wpa_supplicant IBSS patch I found via a Google search, if anyone knows the party responsible, let me know so I can credit them properly!

This is compiled against TI's Omapedia Eclair sources ( ) - since this is a different framework than the B&N stock build, I can't guarantee this will work, won't brick your device, etc. Use at your own risk!

If you encounter any problems, please use this thread to let us all know.

That's all there is to it, enjoy!

I can confirm that this will allow you to connect you Nook Color to an adhoc network created by a Jailbroken iPhone 4 and MyWi.

Cool you figured this out! For some reason, I've been able to use the adhoc network on my Androidized HTC Leo (HD2) since the first time I tried, even before rooting.

My NC is stuck at trying to obtain an IP address from my Droid 1. I'm using Barnacle.

Any ideas?


It took several attempts but it finally connected. Being able to get connected anywhere is awesome. Thanks for posting this!
