Miscellaneous Troubleshooting

Steps	Notes and Detailed Instructions
When there is no Internet connection while updating software (i.e. no network connection)	First, double check that your ethernet cable is securely plugged into both your system and the wall jack. Next, right-click the Network icon on the top panel, next to the time and date, and ensure that Networking is listed as Enabled. Then left-click the Network icon and see if an option appears under Wired Connections (it should say something like auto eth0). If nothing shows up, check the BIOS settings to ensure that the on-board networking feature is enabled (there are several types of BIOS environments, so you may have to do some investigating). If all looks well and you still don't have a connection, try installing a network card. Installing a network card will usually disable the on-board, but reboot and check the BIOS setting to ensure that on-board networking is disabled
"I have optical drive issues"	In most cases, if an optical drive isn't being recognized in a system, or isn't being responsive in some way, the most expedient thing to do is shut down the system, yank out the optical drive, and replace it. If it's a rewritable drive (CD/DVD-RW), mark a small X in Sharpie on the drive and put it back into its appopriate crate. If it's just a readable drive (CD/DVD-ROM), go ahead and put it in the recycle bin underneath the workbench. If you are still having issues after having replaced the optical drive, then grab a build instructor to look over your connections and help you further troubleshoot the problem, or look through the Optical Drive troubleshooting page on the wiki.
"The system will not complete a reboot. It just hangs on the Ubuntu screen. Shutdown works fine."	GRUB is the boot loader package responsible for starting up and shutting down your computer. Try editing the following GRUB configuration file and see if it makes a difference. HINT: if you hit the Esc key while your computer is booting up or shutting down during the Ubuntu splash screen, you may get more text information about what your computer is doing. If you're not comfortable working in a terminal, grab some help on this one. In a terminal, type: sudo gedit /etc/defaults/grub Find the line GRUB_CMDLINE_LINUX_DEFAULT="splash quiet" and edit it to read: GRUB_CMDLINE_LINUX_DEFAULT="reboot=bios splash quiet" Save and exit. In a terminal, type: sudo update-grub Shut down the computer, power on again and try rebooting. Is fixed, no?
