Wireless Security Mode: WPA-Personal

Wi-Fi Protected Access (WPA) is the most advanced and up to date wire-

less encryption method used today. This is the recommended wireless

security option. WPA supports two authentication frameworks. Personal

(PSK) and Enterprise (EAP).

The following parameters will be available for conﬁguration:

WPA Mode:

WPA is the older standard; select this op-

tion if the clients that will be used with the

router only support the older standard.

WPA2 is the newer implementation of the

stronger IEEE 802.11i security standard.

With the “WPA2” option, the router tries

WPA2 ﬁrst, but falls back to WPA if the

client only supports WPA. With the “WPA2

Only” option, the router associates only

with clients that also support WPA2 secu-

rity.

Cipher Type:

Select the appropriate cipher type to use

here. Options to choose from are Temporal

Key Integrity Protocol (

TKIP

), Advanced

Encryption Standard (

AES

), and Both (

TKIP

and AES

).

Group Key Update Interval:

Enter the amount of time before the group

key used for broadcast and multicast data

is changed.

Pre-Shared Key:

Enter the shared secret used here. This secret phrase needs to be the same on all of the wireless clients for them to

be able to connect to the wireless network successfully.

Section 4 - Security

Wireless Security

This section will show you the diﬀerent levels of security you can use to protect your data from intruders. The DIR-803 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)

What is WPA?

WPA (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 router 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 - Conﬁguration

This section will allow you to change the local network settings of the router and to conﬁgure the DHCP settings.

Network Settings

Enter the IP address of the router. The default IP address

is 192.168.0.1.

If you change the IP address, once you click

Save.Settings

,

you will need to enter the new IP address in your browser

to get back into the conﬁguration utility.

Enter the Subnet Mask. The default subnet mask is

255.255.255.0.

Enter a name for the router.

Enter the Domain name (Optional).

Uncheck the box to transfer the DNS server information

from your ISP to your computers. If checked, your

computers will use the router for a DNS server.

Section 3 - Conﬁguration

DHCP Server Settings

DHCP stands for Dynamic Host Control Protocol. The DIR-803 has a built-in DHCP server. The DHCP Server will automatically

assign an IP address to the computers on the LAN/private network. Be sure to set your computers to be DHCP clients by setting

their TCP/IP settings to “Obtain an IP Address Automatically.” When you turn your computers on, they will automatically load

the proper TCP/IP settings provided by the DIR-803. The DHCP Server will automatically allocate an unused IP address from

the IP address pool to the requesting computer. You must specify the starting and ending address of the IP address pool.

Check this box to enable the DHCP server on your router.

Uncheck to disable this function.

Enter the starting and ending IP addresses for the DHCP

server’s IP assignment.

Note:

If you statically (manually) assign IP addresses to your

computers or devices, make sure the IP addresses are outside

of this range or you may have an IP conﬂict.

The length of time for the IP address lease. Enter the Lease

time in minutes.

If all the computers on the LAN successfully obtain their

IP addresses from the router’s DHCP server as expected,

this option can remain disabled. However, if one of the

computers on the LAN fails to obtain an IP address from the

router’s DHCP server, it may have an old DHCP client that

incorrectly turns oﬀ the broadcast ﬂag of DHCP packets.

Enabling this option will cause the router to always broadcast its responses to all clients, thereby working around the problem, at

the cost of increased broadcast traﬃc on the LAN.

Check this box to allow the DHCP Server to oﬀer NetBIOS conﬁguration settings to the LAN hosts. NetBIOS allow LAN hosts to

discover all other computers within the network, e.g. within Network Neighborhood.

If NetBIOS announcement is switched on, it will cause WINS information to be learned from the WAN side, if available. Turn this

setting oﬀ to conﬁgure manually.
