field. The DPH650 supports multiple SSIDs. You may enter up to 3 SSIDs in the
fields provided.
Broadcast Network Name(SSID): You may enable/disable the broadcasting of
your SSID. If you choose to disable the SSID, you will not see the DPH650 when
you use site survey to search available wireless networks.
BSSID: Identifies the Basic Service Set Identifier.
Frequency: Selects the channel for your wireless network.
Wireless Distribution System (WDS): You may extend your wireless networks
by connecting several networks.
Wireless Advanced
The following Wireless Advanced settings provide additional settings for your
wireless functionality.
Beacon Interval: Displays the time interval that the DPH650 uses to announce
itself to remote devices. Leave the Beacon Interval at 100ms for compliance with
most client cards. The Beacon Interval specifies how often packets are sent by
the DPH650 to synchronize a wireless network and its clients.
DTIM Interval: Delivery Traffic Indication Message (DTIM) displays the time
interval between broadcast/multicast transmissions. The DTIM interval is a
countdown informing the wireless clients of the next window for listening to
broadcast and multicast messages. When the DPH650 has buffered broadcast or
multicast messages for associated clients, it sends the next DTIM with a DTIM
Interval value. The DPH650 clients hear the beacons and awaken to receive the
broadcast and multicast messages. Leave the DTIM Interval at 3ms for
compliance with most clients cards.
Fragmentation Threshold: Sets the fragmentation threshold. The threshold
should be set equivalent to the maximum Ethernet frame size allowable on the
link including overhead (1536 bytes). Lesser settings can damage data
throughput as large frames could be fragmented or collisions could occur. The
factory default is 2346.
RTS Threshold: Determines at what packet size beyond which the ready to
send/clear to send (RTS/CTS) mechanism is invoked. The factory default is
2347.
22 4027494 Rev A
Configure the DPH650
Wifi-multimedia
You can enable Wi-Fi Multimedia (WMM) support to help improve the Quality of
Service (QoS) for your wireless traffic. We recommend that you leave the settings
unchanged if you are not sure with your configuration. Changing the values may
lead to unexpected blockages of traffic on your wireless LAN; the blockages may be
difficult to diagnose.
The WMM screen provides two separate menus to set up the parameters: one is for
the DPH650 and the other one is for Wireless Stations.
Typically, voice and video traffic types are delay-sensitive, but are tolerant of some
frame losses. On the other hand, data traffic type is delay-tolerable, but requires loss
free transmission. So you may adjust these parameters with regard to the
characteristics of these types of data to better manage your network flow.
AC (Access Category): Uses the following access categories, which are listed
from high to low:
- VO: Voice
- VI: Video
- BE: Best Effort
- BK: Background
AIFS (Arbitrary Interframe Space): An Interframe Space for different Access
Category
TXOP (Transmission Opportunity): WMM (Wireless Multimedia)
Transmission Opportunity: Defined by IEEE 802.11e, the TXOP is the interval of
time when a particular STA (station) has the right to initiate transmissions.
ACM (Admission Mandatory): Advertised in the EDCA parameter set element
to indicate the admission control is required for each of the ACs.
EDCA AP Parameters: The values of AIFS, CWmin, and CWmax are announced
by the DPH650 via beacon frames. The DPH650 can adapt these parameters
dynamically depending on the network conditions. Basically, the smaller AIFS
and CWmin, the shorter the channel access delay for the corresponding priority,
and hence the more capacity share for a given traffic condition. However, the
probability of collisions increases when operating with smaller CWmin.
4027494 Rev A 23
Configure the DPH650
EDCA STA Parameters: Each station maintains a Contention Window (CW),
which is used to select the random back off counter. The BC is determined as a
random integer drawn from a uniform distribution over the interval (0, CW). The
CW size is initially assigned CWmin, and increases when a transmission fails,
i.e., the transmitted data frame has not been acknowledged. After any
unsuccessful transmission attempt, another back off timer is performed, with an
upper bound of CWmax. This reduces the collision probability in case there are
multiple stations attempting to access the channel.
CW min: Should be smaller for delay-sensitive data
CW max: Should be smaller for delay-sensitive data
AIFSN: Should be smaller for delay-sensitive data
24 4027494 Rev A
Configure the DPH650
TXOPLimit: Allows multiple MAC frames consecutively as long as the whole
transmission time does not exceed the TXOP limit. For delay-sensitive date, keep
this limit larger.
ACM: Admission Mandatory; could be turned on to mandatory execution of the
contention control.
Wireless Security
You may setup the encryption method for your wireless network to better protect
you wireless networks.
Security Mode
Open: For this type of security mode, your wireless connection is unprotected. This
is strongly not recommended.
WEP: This security mode is defined in the original IEEE 802.11. This mode is not
recommended now due to its weak security protection. Users are urged to migrate to
WPA or WPA2.
Default Transmit Key: Select the key to be used for data encryption.
WEP Encryption: Select a level of WEP encryption, 64 bits (10 hex digits) or 128 bits
(26 hex digits). Key 1-4. If you want to manually enter WEP keys, then complete the
fields provided. Each WEP key can consist of the letters "A" through "F" and the
numbers "0" through "9". It should be 10 characters in length for 64-bit encryption or
26 characters in length for 128-bit encryption.
WPA-PSK: This is the WPA Algorithm. WPA offers you two encryption methods,
TKIP and AES for data encryption. Select the type of algorithm you want to use,
TKIP or AES. The default is TKIP.
WPA PreShared Key: Enter a PassPhrase Key of 8-63 characters.
WPA2-PSK: This is the WPA2 Algorithm. WPA2 offers you two encryption
methods, TKIP and AES for data encryption. Select the type of algorithm you want
to use, TKIP or AES. The default is TKIP.
WPA PreShared Key: Enter a PassPhrase Key of 8-63 characters.
802.1x: The 802.1x security method features a use in coordination with a RADIUS
server. This should only be used when a RADIUS server has already been setup in
the LAN.
IP Address: Enter the address of the RADIUS server.

If your DPH650 does not perform as expected, the following tips may help. If you
need further assistance, contact the technical assistance.
Verify that the plug to your DPH650 AC power is properly inserted into an
electrical outlet.
Verify that your DPH650 AC power cord is not plugged into an electrical outlet
that is controlled by a wall switch. If a wall switch controls the electrical outlet,
make sure the switch is in the ON position.
Verify that the ONLINE LED status indicator on the front panel of the DPH650 is
illuminated.
Verify that your cable service is active and that it supports two-way service.
Verify that all cables are properly connected, and that you are using the correct
cables.
Verify that your TCP/IP is properly installed and configured if you are using the
Ethernet connection.
If you are using a cable signal splitter so that you can connect the DPH650 to
other devices, remove the splitter and reconnect the cables so that the AP is
connected directly to the cable input. If the DPH650 now functions properly, the
cable signal splitter may be defective and may need to be replaced.
