Options on this page allow you to control security features that can protect your privacy. Remember that
all devices connected to the wireless network must share the same security settings.
Basic > Advanced > Admin > Status > Shortcuts > Help
• SSID: (Default at&t) The Service Set Identifier is the name of your wireless local area network. The
factory default name is "at&t". For privacy, you should change this to a unique name. If you leave the
default name, users of other wireless networks nearby may have access to your computers or your
Internet access (if they are using the same SSID). Remember that all computers on your network
must share the same SSID.
• Channel: (Default 6
) The router uses radio signals to communicate with other devices on the network.
You can change the frequency by selecting a different channel. Remember that all computers on your
network must use the same channel. Devices using AT&T Plug&Share™wireless adapters will automatically detect the channel used by the router and change to it.
You may have to change the channel if you are experiencing problems such as intermittent connection and disconnection. You can perform a site survey on your wireless adapter to find out which
channels are being used by other wireless networks nearby. If other networks use the same channel
(or an adjacent one), change yours to one as far away as possible from the others in use. (For example,
if other networks use channels 6, 9 and 11, try changing yours to channel 1.)

router or access point (see settings below).
• WEP Encryption: (Default 64 bit
) This option sets the encryption strength (you can choose 64, 128 or
256-bit encryption). Higher numbers provide more protection, but slower network performance.
Remember that all computers on your network must use the same encryption strength.
• Key Type: (Default ASCII
) You should leave this setting as it is if you want to use alphanumeric
characters as security phrases (see description below). The HEX setting allows you to use hexadecimal
code as security phrases.
• Security Phrases: (No default) Enter a security phrase. If you choose the Hex Key Format (see above),
you must use hexadecimal digits (0-9, a-f). If you choose the ASCII Key Format you can use letters, numbers, spaces, and punctuation marks. You must enter five characters for 64-bit, 13 characters for 128-bit
or 29 characters for-256 bit encryption. All devices on your wireless network must use the same security
phrase you enter here. You can create up to four different security phrases, for different wireless networks.

Filters
Filters allow you to control Internet access from networked computers. Options allow you to restrict
access to specific web sites, restrict access to all web sites except those you designate, or restrict
access to other computers on your local area network (LAN). There are four types of filters:
• IP filters: Prohibit Internet access by particular LAN IP addresses (see below).
• MAC filters: Prohibit Internet access or LAN access by specific computers (see page 25).
• URL blocking: Prohibit access to groups of web sites by key word (see page 26).
• Domain blocking: Prohibit access to web sites specified by name (see page 27).
