If your connection problem disappears, the problem lies in the Wi-Fi® part of your network. ❖ 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. 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.
