It is recommended to use iPoll protocol for simple Point to Point network configuration.

Follow the steps to create a  simple Point to Point link between Access Point iPoll and Station (iPoll):

Step 1.  Access Point iPoll configuration: change device’s default IP address (can be static or dynamic), enable IP alias if necessary:

ptmp-step1

Step 2.     Configure wireless  settings for Access Point iPoll:

- Select wireless mode: Access Point iPoll
- Define SSID
- Set channel: Auto
- Enable Security for secure traffic on link
all other settings should be left default:

PTP-wireless

Step 3.    Station iPoll configuration: change device’s default IP address (can be static or dynamic), enable IP alias if necessary:

PTP-network

Step 4.     Configure wireless  settings for Station iPoll:

- Select wireless mode: Station (auto iPoll)
- Define SSID, or use “Scan” button to find iPoll Access Points automatically
- Enable Security for secure traffic on link
all other settings should be left default:
Note that Station iPoll security settings must conform the settings configured on the Access Point iPoll that station is associated with.

PTP-wireless-station

Step 5.     It is highly recommended to change default administrator’s password for each unit:

PTP-password

Step 6. Verify the PTP link  connection.  Navigate to the Status | Information page. The Information page will display wireless information of the link.

The status page of the Access Point iPoll must indicate that one peer (Station iPoll) is connected and information about connection must be displayed as follows:

PTP-status-APiPoll

The status of the Station iPoll must be displayed as Connected and progress bars indicating the quality of the connection must be displayed:

PTP-status-StationiPoll

Point to Multipoint bridged network configuration

PTMP

 

In a bridged (layer 2) network could be used in WDS or ipoll modes. Ipoll mode should be used when AP and all stations are Deliberant products otherwise select WDS mode. Recommended maximum stations per AP can be from 60 to 70.
Configuration
Change device’s IP address (can be static or dynamic), enable IP alias if necessary. Default ip address could be left because it is used for device management.

Station Wirelles section configuration steps:

-Select country code
-Select wireless mode: Station WDS

According to access point:

-Define SSID
-Choose IEEE mode
-Set Max data rate N to “Auto”
-Enable Security if necessary
-Set ACK timeout based on max distance from the station
-Leave all other settings as default

stationPTMP

Observe signal levels at Access point and at Station. Recommended signal level range is from -35 to -60 dBm.

 

If the device is MIMO, there are two signal streams. One of them is called as “Main” (Antenna 1), another is “Aux”
Main stream is mandatory. If main signal is very weak, the link will not be stable or will not work at all. It is necessary, to align the antennas for the best main signal. If Aux stream is weak, the link will work at lower data rate. Check if SNR is  good on AP and Station and it is over 20/20.

The HotSpot scenario is popular in the various public places like an airport, shop, bar or stadium. The APC allows user authentication through external or internal Web portal. This authentication method is called UAM. User provides login credentials and then Web portal attempts to authenticate and authorize the client using the provided information. Client will not send any authentication requests directly to the APC, the Web portal will do this. On success, APC will allow access to the Internet; otherwise Web portal will display failure notice.

Hot-spot-zone

Follow the steps to configure a Hotspot  UAM authentication through external Web portal, for wireless clients.

Step 1.   Configure network settings: the HotSpot with UAM authentication is available only if APC operates as Router.

hotspot-network

Step 2.   Setup wireless  settings for HotSpot:

- Select wireless mode: Access Point (auto WDS)
- Define SSID
- Set channel: Auto
- Choose wireless security: UAM
hotspot-wireless
Step 3.   Setup UAM authentication with External web/login page (hosted on separate web server):
-Add at least one RADIUS server settings: IP addres, RADIUS secret, authentication and accounting ports

-Setup the External UAM fields: login page URL, welcome page URL, blacklist URL and logout URL

-UAM configuration can be automatically updated from the server at scheduled time

-UAM supports Hotspot description according to WISPr 1.0 recommendation: WISPr location name, operator name, network name, ISO country code, E.164 country code, E.164 area code

-UAM supports traffic limitation and has fields for default bandwidth definition. These parameters/attributes can be overridden per user from the RADIUS.

hotspot-external-uam

Step 4.   Additionally the following settings can be configured for the UAM autrhentication:
-WPA-PSK encryption can be used on UAM for a stronger security
-UAM supports white/black list which can be configured statically on the device or can be updated automatically from the server
-UAM has an option for AP monitoring through HTTP URL

hotspot-uam-optional

Step 5.   After the UAM authentication is successfully configured on the APC, all wireless clients will be redirected to the External Web portal for authentication.

Virtual AP
Virtual AP functionality is available only in Access Point (auto WDS) wireless mode.

Use the Configuration | Virtual AP page to configure to create up to 7 additional Virtual AP interfaces. The Virtual AP defines a logical wireless network, and the APC can be configured to provide additional 7 wireless networks on each device radio. All the VAPs may be active at the same time meaning that client devices can associate to the APC using any of the VAP SSID.

The Virtual AP table displays a summary of all virtual radio interfaces running on the APC:

VAPS1

To create a new Virtual AP, click on + button to add new entry on the VAP table, then select this entry and specify required parameters:

SSID – specify the unique name for the VAP [string].

Broadcast SSID – when this option is selected the particular SSID is visible during network scans on a wireless station. When unselected, the VAP SSID is not visible and not broadcasted to wireless stations.

Quality of service (WMM) – enable to support quality of service for prioritizing traffic.

Client isolation – enable the user Layer 2 isolation. The Layer 2 isolation blocks the wireless clients from communicating with each other.

Max clients limit – specify the maximum number of associated wireless clients per VAP.

Each VAP security is configured by default as an “open system”, which broadcasts a beacon signal including the configured SSID. For more secure network choose one of the security mechanisms for each VAP interface.

Security – choose the wireless security and encryption method from the drop-down list.

Wireless clients must be able to respond with a specific security configuration
VLAN to SSID mapping

Virtual Local Area Networks (VLANs) are logical groupings of network resources.

VLAN to SSID mapping – specify the VLAN ID for traffic tagging on required radio interface [2-4095]. The Station devices that associate using the particular SSID will be grouped into this VLAN. Configuration window is in Configuration/Network section.  When device interfaces are configured with a specific VLAN ID value in Management section, only management frames that matching configured VLAN ID will be accepted by device. Restrict management is used when stations have to be management via VLAN too.

vlantossid1

Network management is available only on Bridge network mode
For IP eth0 is mandatory because it is interface to the network
When you specify a new management VLAN, your HTTP connection to the device will be lost. For this reason, you should have a connection between your management station and a port in the new management VLAN or connect to the new management VLAN through a multi-VLAN router

repeaterpicture

Use Access Point Repeater mode in order to extend the range of the existing network infrastructure. The Access Point repeater’s wireless settings has possibility to scan SSID of the surrounding APs and choose the required one. Enable WDS when the main AP is working in WDS mode too. Do not forget to add security information which is needed to connect to main AP. Also country code should be the same on all devices.

Repeater Basic Wireless Settings

SSID – specify the SSID of the remote access point.

Enable/Disable WDS –  specifies Access Point Repeater mode WDS or non WDS

Scan – click this button to scan for surrounding wireless networks. Found network SSID’s will be available in drop down menu.

Peer Access Point MAC address – enter the MAC address of the remote access point.

Broadcast SSID – enable or disable the broadcasting of the SSID.

IEEE mode – specify the operating wireless mode.

Channel width – The default channel bandwidth for 802.11 radio is 20MHz. The 802.11n allow channel bonding in such way the total channel width becomes 40MHz.

1. Set wireless mode to Access Point Repeater and go into Peer AP settings

AP_repeater2_x95

2. Scan and choose AP SSID which is going to be repeated.

AP_repeater_x95

Both sides (AP and Repeater Peer) of the link must have the same security settings.

3. In Basic and Security sections there could be added the same as main AP SSID and Security information or created new one.

AP_repeater1_x95

WDS mode should be disabled when main AP is working in regular non WDS mode. Commonly used when trying to repeat simple wireless router.

Step 4. WAN Settings WAN network settings include settings related to the WAN interface. In this scenario WAN interface is from wireless side. The access type of the WAN interface can be configured as: Static IP, Dynamic IP, PPPoE client. WAN mode – choose Static IP to specify IP settings for device WAN interface:

Set static IP from the same subnet as is AP device. Then you could reach station from your netwrok

WAN1

Step 4. DHCP mode – choose server to enable DHCP server on LAN interface.

In IP address field set address with which you could reach device via wired LAN

Lan Wired1

IP address from – specify the starting IP address of the DHCP address pool.
IP address to – specify the ending IP address of DHCP address pool.
Subnet mask – specify the subnet mask.
Default gateway – specify DHCP gateway IP address.
Lease time – specify the expiration time in seconds for the IP address assigned by the DHCP server.

Step 5. Test the configuration.

How to configure PPPoE client

In router mode the DLB APC will receive internet through WAN port and will share it to the LAN ports that will be separated with a different IP range. The type of connection to the WAN interface can be made by Static IP, DHCP client or PPPoE.

WAN mode – choose PPPoE to configure WAN interface to connect to an ISP via a PPPoE. In main configuration should be added Username, Password all other settings should be left by default:

PPPoE

Parameters explanaition:

MAC address – specify the clone MAC address if required. The ISPs registers the MAC address of the router, and allows only that MAC address to connect to their network. In such case if there is need to change hardware (router), you need to notify your ISP about MAC address change, or simply set the router’s MAC address to the MAC address of the previously router/computer.

VLAN ID – specify the VLAN ID for traffic tagging on required radio interface [2-4095]. The Station devices that associate using the particular SSID will be grouped into this VLAN.

User name – specify the user name for PPPoE.

Password – specify the password for PPPoE.

MTU – specify the MTU (Maximum Transmission Unit). The default value is 1500 bytes.

Reconnect mode – specify PPPoE reconnection mode:

Always on – PPPoE connection automatically starts without timeout. The router will keep trying to bring up the connection if it is disconnected for some reason.
On demand – the PPPoE connection automatically starts when there is outbound traffic to the Internet, and it automatically terminates if the connection is idle based on the value specified in the Idle time [1-65535] setting.

DNS settings – allows selecting if automatically assigned or alternative DNS servers should be used.

Enable IP alias – specify the alternative IP address and the netmask for APC unit management.
