Problem
The Above bug, or the absence of battery indicator on the upper panel is a commonly found issue with ubuntu 11.10 installations. cause of this issue is different machine to machine
Solutions
There are a handful of ways to solve the battery indicator problem. and my solutions are listed below

1.  Purge and re-install indicator-power
     
    sudo apt-get purge indicator-power

     sudo apt-get install indicator-power

2. Change theme to  'Radiance'.or change away from Radiance,

    to  Make sure this is not an icon issue.

3.  Remove revenants from Unity if any,

1. (get settings, for curiosity's sake)
   gsettings get com.canonical.Unity.Panel systray-whitelist
   
   (should look something like:)
   ['JavaEmbeddedFrame', 'Wine', 'scp=-dbus-service', 'Update-notifier']
   
   (clear whitelist)
   gsettings set com.canonical.Unity.Panel systray-whitelist "['all']"

  4. Try an alternative battery monitor package

Ubuntu 11.10 wireless problem: Solved

Ubuntu 11.10 is awesome but the following issue is found in many installations

Problem: When I try to connect to the internet using wi-fi a pop-up message asks the password as usual and after I type it correctly it shows a notification box telling me that I'm disconnected. If I connect the cable directly it works perfectly


Solution: This issue is hardware dependent .most of the machines are coming with wireless device which will require installation of additional drivers, once you update the ubuntu 11.10 OS , it will start prompting you to install additional drivers for wireless device. click OK, and authenticate the request the OS will automatically find the appropriate driver. after a restart the issue will be fixed.
