Connect your computer directly to your router or broadband
modem, by plugging a standard CAT5 Ethernet patch cable
(sold separately) into your computer's RJ45 Ethernet port. 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.
