Installation & Basic Configuration
Configure the Ethernet Interface
1. Click Configure > Interfaces > Ethernet.
2. Set the Speed and Transmission Mode for the AP’s Ethernet interface.
• This is the speed and duplex at which the AP communicates with your Ethernet network. By default, the AP
automatically detects the settings of the hub or switch to which it is connected. If you are having problems
communicating with the AP over the Ethernet, manually set the mode to match your hub or switch’s settings.
Options include:
— 10 Mbits/sec and half-duplex
— 10 Mbits/sec and full-duplex
— 10 Mbits/sec and auto-duplex
— 100 Mbits/sec and half-duplex
— 100 Mbits/sec and full-duplex
— Auto-speed and auto-duplex (the default setting)
3. Click OK.
Set WEP Encryption for each Wireless Interface
The IEEE 802.11 standards specify an optional encryption feature, known as Wired Equivalent Privacy or WEP, that is
designed to provide a wireless LAN with a security level equal to what is found on a wired Ethernet network. WEP
encrypts the data portion of each packet exchanged on an 802.11 network using an Encryption Key (also known as a
WEP Key).
When Encryption is enabled, two 802.11 devices must have the same Encryption Keys and both devices must be
configured to use Encryption in order to communicate. If one device is configured to use Encryption but a second
device is not, then the two devices will not communicate, even if both devices have the same Encryption Keys.
•
The AP-2500 supports 64-bit and 128-bit encryption (for both 802.11a and 802.11b), depending on the type of
cards inserted into the AP’s slots.
–
For 64-bit encryption, an encryption key is 10 hexadecimal characters (0-9 and A-F) or 5 ASCII characters
(see
ASCII Character Chart ).
– For 128-bit encryption, an encryption key is 26 hexadecimal characters or 13 ASCII characters. Note that
some 802.11b cards do not support 128-bit encryption.
NOTE
64-bit encryption is sometimes referred to as 40-bit encryption; 128-bit encryption is sometimes referred to as
104-bit encryption.
Keep in mind that if you enable WEP encryption on the wireless interfaces, you will need to inform your subscribers of
these settings and they will need to reconfigure their wireless cards with these settings before gaining access to the
network (and before they are prompted to logon to the hotspot).
Follow these steps to configure WEP:
1. Click Configure > Security > Encryption.
2. Place a check mark in the Enable Encryption (WEP) boxes as necessary.
• If you only have one wireless card installed, only one box will appear; two boxes appear if you have two cards
installed.
• If two cards are installed, you can enable encryption for either or both of the wireless slots (Slot A and/or
Slot B).
3. Enter one to four Encryption Keys in the fields provided. Keep in mind the following:
• If entering more than one Key, use the same number of characters for each Key. All Keys need to be the same
Key Size (64 or 128-bit). The card must support the Key Size that you specify (some 802.11b cards do not
support 128-bit encryption).
• You can enter the Encryption Keys in either hexadecimal or ASCII format.
• You need to configure your wireless clients to use the same Keys in order for the clients and the AP to
communicate. Subscribers that do not have the same encryption settings will be unable to login at the hotspot.
4. Set Deny Non-Encrypted Data to Enable if you want to prevent clients that do not have WEP enabled or the
proper keys configured from communicating with the network. Enabled is the recommended settings.
