Ubuntu 12.04 hotspot wifi network not visible to Android 4.1.2

androidUbuntuwifi

I'm running Ubuntu 12.04 LTS on my notebook, and I've got a Motorola Razr which I updated to Android 4.1.2. Before updating, I connected my smartphone to my hotspot wifi very quickly, but after the update it no longer works. Android 4.1.2 can't see the hotspot created by Ubuntu; it sees all other wifi networks and can connect to them, but not mine. What could be wrong?

You can use ap-hotspot from the webupd8 repository to create an infrastracture AP instead of adhoc. I am using this on Ubuntu Precise (12.04), but it is available for Saucy, Raring and Quantal as well.

$ sudo su -
# add-apt-repository ppa:nilarimogard/webupd8
# aptitude update
# aptitude install ap-hotspot
# ap-hotspot configure
# ap-hotspot start
