You can select the types of messages that you want

to display from the log.

There are three levels of message importance:

Informational, Warning, and Critical. Select the

levels that you want displayed in the log.

Will ﬁlter the log results so that only the selected

options appear.

Clicking this button refreshes the display of log

entries. There may be new events since the last

time you accessed the log.

Clicking this button erases all log entries.

Select this option to save the bridge log to a ﬁle on

your computer.

Logs

The bridge automatically logs (records) events of possible interest in its internal memory. If there is not enough internal

memory for all events, logs of older events are deleted, but logs of the latest events are retained. The Logs option

allows you to view the bridge logs. You can deﬁne what types of events you want to view and the level of events to view.

This bridge also has external Syslog Server support so you can send the log ﬁles to a computer on your network that

is running a Syslog utility.

Section ³ - Security

Wireless Security

This section will show you the different levels of security you can use to protect your data from intruders. The

DAP-1555 offers the following types of security:

• WPA2 (Wi-Fi Protected Access 2)

• WPA2-PSK (Pre-Shared Key)

• WPA (Wi-Fi Protected Access)

• WPA-PSK (Pre-Shared Key)

• WEP (Wired Equivalent Privacy)

What is WEP?

WEP stands for Wired Equivalent Privacy. It is based on the IEEE 802.11 standard and uses the RC4 encryption

algorithm. WEP provides security by encrypting data over your wireless network so that it is protected as it is transmitted

from one wireless device to another.

To gain access to a WEP network, you must know the key. The key is a string of characters that you create. When using

WEP, you must determine the level of encryption. The type of encryption determines the key length. 128-bit encryption

requires a longer key than 64-bit encryption. Keys are deﬁned by entering in a string in HEX (hexadecimal - using

characters 0-9, A-F) or ASCII (American Standard Code for Information Interchange – alphanumeric characters) format.

ASCII format is provided so you can enter a string that is easier to remember. The ASCII string is converted to HEX

for use over the network. Four keys can be deﬁned so that you can change keys easily.

Section ³ - Security

What is WPA?

WPA, or Wi-Fi Protected Access, is a Wi-Fi standard that was designed to improve the security features of WEP (Wired

Equivalent Privacy).

The 2 major improvements over WEP:

• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys

using a hashing algorithm and, by adding an integrity-checking feature, ensures that the keys haven’t

been tampered with. WPA2 is based on 802.11i and uses Advanced Encryption Standard (AES) instead

of TKIP.

• User authentication, which is generally missing in WEP, through the extensible authentication protocol

(EAP). WEP regulates access to a wireless network based on a computer’s hardware-speciﬁc MAC

address, which is relatively simple to be sniffed out and stolen. EAP is built on a more secure public-key

encryption system to ensure that only authorized network users can access the network.

WPA-PSK/WPA2-PSK uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric

password between 8 and 63 characters long. The password can include symbols (!?*&_) and spaces. This key must

be the exact same key entered on your wireless bridge or access point.

WPA/WPA2 incorporates user authentication through the Extensible Authentication Protocol (EAP). EAP is built on a

more secure public key encryption system to ensure that only authorized network users can access the network.

Section ³ - Security

Conﬁgure WEP In AP Mode

It is recommended to enable encryption on your wireless access point before your wireless network adapters. Please

establish wireless connectivity before enabling encryption. Your wireless signal may degrade when enabling encryption

due to the added overhead.

1.

Log into the web-based conﬁguration by opening a web browser and entering the IP address of the access point

(192.168.0.50).

Click on

Setup

and then click

Wireless Settings

on the left side.

2. Next to

Security Mode

, select

WEP

.

3. Next to

WEP Key Length

, select the level of encryption (64

or 128-bit).

Hex

- (recommended) Letters A-F and numbers 0-9

are valid.

4. Next to

WEP Key 1

, enter a WEP key that you create. Make

sure you enter this key exactly on all your wireless devices.

You may enter up to 4 different keys.

5. Next to

Authentication

, select

Open or Shared Key

.

6. Click

Save Settings

to save your settings. If you are

conﬁguring the access point with a wireless adapter, you will

lose connectivity until you enable WEP on your adapter and

enter the same WEP key as you did on the access point.
