Page 5(17)
•The wireless network you want to connect to has a DHCP server (it gives you an IP address
automatically).
•No wireless encryption is used.
How to connect to a network:
1. Ensure that the correct frequency range is chosen.
2. Press the Site Survey button in the Basic tab and wait 20-30 seconds until the scan is performed.
3. The network that your service provider has set up should be visible in the Site Survey window. Left
Click on the SSID of the network that you want to connect to. It will automatically be filled in the
SSID field under Radio Settings.
4. Press the Apply button.
When the signal strength is optimized, click the Refresh button in the lower, right corner of the screen until
your SU has received an IP address from the network. When this is done, the connection is established and
the connection is configured.
Received signal strength display methods in CPE
Signal levels and behaviour.
Received signal (dB)
Expected behaviour
0 – 15
Below 15 dB will in most cases not produce any good connection
15 – 20
Will cause a connection but not acceptable
20 – 25
Acceptable connection
25 - above
Good connection
The CPE has two basic methods to display the received signal strength from the base station.
Method 1: Measure through CPE web interface
In “Status” and “Basic” tabs you will find signal strength in percent and RSSI value.
28 dB in RSSI value is the measured signal level above noise floor (-95dB). The 84% signal strength bar is
a calculated percentage of a fix maximum signal strength level of 33 dB. Push “Refresh” to update the
information.
By performing a “Site Survey” the CPE will scan all frequencies for a very short time period and the
showed value is not very specific. When performing a fine-tuning, always use the “Refresh” function
instead of “Site Survey”

Page 6(17)
Method 2: Measure with CPE signal LED on the back of the unit
All outdoor units
The signal strength led can be set into 3 different ways and is set in the “Maintenance” tab. Off, Pulse and
Continues can be set where the Puls method is default.
The Pulse method shows the signal level in 7 steps:
No pulse
Not associated
1 pulse
1 -9 dB signal
2 pulses
10 -14 dB signal
3 pulses
15 – 19 dB signal
4 pulses
20 – 24 dB
5 pulses
25 – 29 dB
6 pulses
+30 dB

Software setting
Status tab
The status tab shows you the current connection and IP-status of the SU. Depending on the current
connection method the status tab shows different information. On the top you will find an indicator of the
current connection status and signal strength. Also you find statistics for the radio interface.
Status tab in Bridging Mode
Connection method
BRIDGING:The SU works as a transparent layer two switch
TCP/IP Settings
DATA VLAN: Indicates if and what VLAN all data traffic is associated with.
VLAN 0 means that no VLAN is used.
Traffic with no VLAN-tag received on the Ethernet port will
be tagged with this VLAN. Traffic with this VLAN
transmitted on the Ethernet port will be untagged.
LAN HW address: This is the SUs MAC address used on the Ethernet port. (In
bridge mode this is the only MAC address used by the SU)
IP address: This is the current IP address that the SU could be reached on
from the Ethernet port.
Netmask: This is the SUs current netmask defining the size of the
subnet.
Status tab in Routing mode
Connection method
ROUTING: The SU works as a router and performs NAT between the
WAN and LAN port.
LAN TCP/IP Settings
LAN HW address: This is the SUs MAC address used on the Ethernet
port.
LAN IP address: This is the current IP address that the SU could be reached on
from the Ethernet port. This is the IP address that user
equipment should set as gateway.
Netmask: This is the SUs current net mask defining the size of
the LAN subnet.
WAN TCP/IP Settings
WAN HW address: This is the SUs MAC address used on the
WAN port (radio).

Page 8(17)
VLAN: Indicates if and what VLAN all data traffic is
associated with. VLAN 0 means that no VLAN is
used. All traffic sent on the radio interface will be tagged with
this VLAN.
Method: Shows if the WAN IP is static or if it should get an
IP address with DHCP.
IP address: Shows the current IP address on the WAN port.
This is the IP-address delivered by or assigned by
the ISP.
Netmask: The current net mask for the WAN port.
Gateway: The current gateway address for the WAN port.
Primary/Secondary DNS: This is the DNS address used by the SU for
DNS queries.
Commands
DHCP Release: By pressing this button the SU will release its current IP-
address.
DHCP Renew: By pressing this button the SU will try to renew the IP-
address.
Refresh: By pressing this button the SU will update the status page.
Basic tab
The Basic tab holds configuration parameters regarding the connection. At the top you find the
“SiteSurvey” result area. Here the result of a SiteSurvey is presented. When the CPE isn’t connected with
an AP this area will present the CPEs current list of APs that it hears. If the CPE is connected to an AP and
you want to know what other APs that are in range you need to perform a SiteSurvey to update this list.
Left click with the mouse over the Site Survey button. To choose a particular AP to connect to click on the
BSSID and the fields will automatically be filled in with the correct values, then press apply.
Radio Settings
Frequency: Choose which frequency mode should be used. 802.11a means
5 GHz. 802.11b and 802.11g uses 2.4 GHz. (only SU5411abg)
Rate: Configures which rate the SU should use when transmitting
frames. Auto means that it automatically chooses the best rate
depending on the quality of the radio connection.
SSID: This is the SSID of the base station that the SU wants to
connect to.
BSSID: If several base stations have the same SSID you could force
the SU to connect to a particular base station by entering it
BSSID.

Page 9(17)
DATA VLAN: This is the VLAN that should be used for all data traffic;
traffic entering and leaving the LAN port will be
tagged/untagged with this information. 0 means that no VLAN
is used.
Force active Scan: Active Scan needs to be applied if the Base Station has hidden
SSID in 802.11a mode.
Preamble: Controls if transmitted frames should be preceded with a short
or long preamble. Not valid in all modes.
Guard interval:Controls the time between consecutive OFDM symbols. Only
valid in 802.11N mode.
Antenna: Choose between the primary (internal) and the Secondary (N-
connector) antenna. (Not on all types of units)
Encryption:
In the encryption section you configure the security settings of the SU
Encryption settings, the SU supports several encryption methods. WEP, WPA1 and WPA2 with PSK. Two
different cipher methods are available when using WPA, TKIP and CCMP. Choose the correct encryption
method and cipher from the drop down menus. Then enter either the correct WEP keys or pass phrase and
press apply.
WEP keys
If the wireless network makes use of WEP keys, the WEP keys settings must be configured in the SU. To
adjust the WEP settings, access the tab Security. Under Encryption settings, change the selection from
Disabled to either WEP 128-bit or WEP 64-bit depending on what details your ISP has given you.
The WEP key consists of hexadecimal numbers (0-9 and A-F), and the length of the key is depending on
the chosen key size (64 or 128 bits). If a 64-bit key is used, ten hex numbers shall be typed in the WEP key
field. If a 128-bit key is used, 26 hex numbers shall be typed in. The key shall be provided by the ISP.
The Authentication method used is Shared key. It is also important that the right WEP key number to use is
chosen. For example, if the base station uses WEP key #1, the SU also has to use this key number. Your
ISP should provide the number. To store the settings, press Save settings.
WPA
If the wireless network makes use of WPA you need to configure the correct settings here. Choose between
WPA1 and WPA2, also you need to choose which cipher method the CPE should use.
Encryption: You can choose between WPA1 and WPA2, the CPE supports
PSK method (PreSharedKey)
Cipher: Choose the correct cipher method supported modes are TKIP
and CCMP/AES.
Pre-Shared key: Enter the secret key used for the encryption.
If you are unsure about the encryption settings please consult the settings in you AP or the information
provided by the ISP.
