❖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.

The Windows® operating system wireless management utility

does not work.

If you are using an external Wi-Fi® adapter (a 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 utility, 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:
1Verify that the disc is in a format that the drive supports.
2Ensure that the disc is properly inserted in the drive tray.
3Use the DVD Player software that came with your computer to view
DVD movi es.

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.
5Verify that your computer recognizes your optical drive by
clicking Start, and then Computer. The optical drive should
appear in the list.
