sometimes fast, sometimes slow
Problem Solution
• Another network nearby may be using the same channel, and
causing interference. Change the Channel to a different setting
on all devices connected to your network (see page 8).
Troubleshooting
If your wireless network adapter does not work properly, try the following suggestions before seeking
repair assistance.
Cannot connect to the Internet • Verify that your cable or DSL modem is properly connected
and is receiving electrical power.
• Turn off your modem, leave it off for 15 seconds, then turn it
back on and check for Internet access.
• Confirm that your ISP account information is entered correctly
on the router you are using for your Internet connection.
• Do you have Internet access at the computer connected to
your router or access point? If not, you will not be able to
connect until the router fault is corrected. Consult the user
manual for the router or access point.
• If your router or access point is connected to the Internet, try
rebooting the computer in which the adapter is installed.
• Check the communication between the adapter and the
router. If you are using an AT&T Plug&Share
™
router, open
your Internet browser on the computer that has the adapter
installed. Enter A
TT.Router or http://192.168.0.1 in the address
line. If you see the router page, there may be a problem with
your network settings. See next page for instructions.
No access to other devices on
the network
• Make sure the router power light is on. If not, check the AC
power adapter connections at the router and at the wall outlet.
• Make sure all devices connected to the network are assigned
the same SSID
and the same Channel
(see page 8).
• If you have enabled WEP encryption, make sure all devices
use the same encryption settings (see page 9).
• If you have difficulty with file sharing or printing, you must
configure your Windows
®
operating system properly for all
devices connected to the network (see page 10).
