-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.

-Most desktop systems have on-board network capabilities.  Sometimes, this hardware can be bad.  In the case that you have the ethernet chord properly connected to the ethernet plug in the on-board outlet and you don't get a connection, 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.  You will be able to find one in the middle island with other cards, tools and drives. 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, and also ensure that the network card is recognized in BIOS.
+First, double check that your ethernet cable is securely plugged into both your system and the wall jack.

-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 safely shut down the system, yank out the optical drive, and replace it.  If its a rewritable drive, kindly mark an "X" by the "Tested by" sticker and place it where optical drives go under the work bench below the research station.  If its just a readable drive, please still mark an "X" somewhere on the optical drive, and place it back in the proper bin of the supplies island of the build area.  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.
