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.

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 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.

If you experience a problem playing DVDs or BDs, you may be 
able to fix the problem yourself. 

For general problems playing a DVD or BD title, try the following 
steps:

Verify that the disc is in a format that the drive supports.

Ensure that the disc is properly inserted in the drive tray.

Use the DVD or BD player software that came with your computer 
to view DVD or BD movies.
