Ubuntu 11.10 problem: Waiting for network configuration : Solved

Hi all! Here is another critical problem solved.

Problem: Many of the newly installed ubuntu machines reporting the following issue. A message " Waiting for network conffiguration"  followed by “Waiting up to 60 seconds more for network”? This then might be accompanied by a black blank screen.


Solution:

• Press Ctrl+Alt+F1 at the blank screen to get you to a non-X terminal (tty1)

• enter your username and password when prompted
• Change to root with: sudo -i and enter your password when asked.
• then type each of the lines followed by enter.
• mkdir -p /run /run/lock
• rm -rf /var/run /var/lock
• ln -s /run /var
• ln -s /run/lock /var
• reboot your system and you should get your Ubuntu 11.10 back in action

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.
