180 If Something Goes Wrong DVD operating problems ❖ If you have enabled any security provisions (closed system, MAC address filtering, Wired Equivalent Privacy [WEP], etc.), check the access point vendor's Web site for recent firmware upgrades. Problems with WEP keys, in particular, are frequently addressed in new firmware releases. The Windows® operating system wireless management facility does not work. If you are using an external Wi-Fi® adapter (an ExpressCard®, USB adapter, or other variety), check if the adapter comes with its own management utility. If it does, the utility may be disabling the Windows® operating system wireless management facility, in which case you must use the adapter's management utility. If the documentation that accompanies the adapter does not provide enough information to determine if this is the case, contact that vendor's support group for further advice. DVD operating problems If you experience a problem playing DVDs, you may be able to fix the problem yourself. For general problems playing a DVD title, try the following steps: 1 Verify that the disc is in a format that the drive supports. 2 Ensure that the disc is properly inserted in the drive tray. 3 Use the DVD Player software that came with your computer to view DVD movies. 4 Clean the disc and try again. A dirty drive can also cause audio problems. If you have tried several discs and all fail, consider sending your drive to an authorized service provider to get it cleaned. 5 Verify that your computer recognizes your optical drive by clicking Start, and then Computer. The optical drive should appear in the list. 6 See "Checking device properties" on page 165 for instructions on using Device Manager to view the optical drive properties. 7 Check the Toshiba Web site for new information on optical drives and their operation.
