D-Link DIR-850L User Manual

The following parameters will be available for conﬁguration:

Wireless Band:

Displays the wireless band being conﬁg-

ured. In this option we ﬁnd that the fol-

lowing parameters will be regarding the

5GHz band.

Enable Wireless:

Check the box to enable the wireless func-

tion. If you do not want to use wireless,

uncheck the box to disable all the wireless

functions. Select the time frame that you

would like your wireless network enabled.

The schedule may be set to Always. Any

schedule you create will be available in

the drop-down menu. Click New Schedule

to create a new schedule.

Wireless Network Name:

The Service Set Identiﬁer (SSID) is the name of your wireless network. Create a name using up to 32 characters. The

SSID is case-sensitive. Enable Auto Channel

802.11 Mode:

Here the user can manually select the preferred frequency band to use for this wireless network.

Enable Auto Channel Scan:

The auto channel selection setting can be selected to allow this device to choose the channel with the least

amount of interference.

Wireless Channel:

By default the channel is set to 36. The Channel can be changed to ﬁt the channel setting for an existing wireless

network or to customize the wireless network. If you enable Auto Channel Selection, this option will be greyed out.

Transmission Rate:

Select the transmit rate. It is strongly suggested to select Best (Automatic) for best performance.

Channel Width:

When using the 802.11n frequency band, the user have an option to choose between a 20 MHz, 20/40 MHz, or

20/40/80 MHz bandwidth.

Visibility Status:

The Invisible option allows you to hide your wireless network. When this option is set to Visible, your wireless

network name is broadcasted to anyone within the range of your signal. If you are not using encryption then they

could connect to your network. When Invisible mode is enabled, you must enter the Wireless Network Name (SSID)

on the client manually to connect to the network.

By default the wireless security of this router will be disabled. In this

next option the user can enabled or disable wireless security for the

frequency band 2.4GHz. There are two types of encryption that can be

used. WEP or WPA/WPA2.

Wireless Security Mode: WEP

Wired Equivalent Privacy (WEP) is the most basic form of encryption

that can be used for wireless networks. Even though it is known as a

‘weak’ security method, it is better than no security at all. Older wireless

adapter sometimes only supports WEP encryption and thus we still ﬁnd

this encryption method used today.

The following parameters will be available for conﬁguration:

WEP Key Length:

Here the user can specify to either use a

64Bit or a 128Bit encrypted key.

Authentication:

Authentication is a process by which the

router veriﬁes the identity of a network

device that is attempting to join the wire-

less network. There are two types authen-

tication for this device when using WEP.

Open System

allows all wireless devices

to communicate with the router before

they are required to provide the encryp-

tion key needed to gain access to the

network.

Shared Key

requires any wire-

less device attempting to communicate

with the router to provide the encryption

key needed to access the network before

they are allowed to communicate with the

router.

WEP Key 1:

Enter the WEP key used here. For 64-bit keys you must enter 10 hex digits into each key box. For 128-bit keys you

must enter 26 hex digits into each key box. A hex digit is either a number from 0 to 9 or a letter from A to F. You

may also enter any text string into a WEP key box, in which case it will be converted into a hexadecimal key using

the ASCII values of the characters. A maximum of 5 text characters can be entered for 64-bit keys, and a maximum

of 13 characters for 128-bit keys.

D-Link DIR-850L User Manual

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.

RADIUS Server IP Address:

When the user chooses to use the EAP

authentication framework, the RADIUS

server’s IP address can be entered here.

RADIUS Server Port:

When the user chooses to use the EAP authentication framework, the RADIUS server’s port number can be entered

here.

RADIUS Server Shared

Secret:

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.
