LANconfig:
- WLAN network enabledThis switch enables or disenables the corresponding logical WLAN.
- Network name (SSID) Specify a unique SSID (the network name) for each of the required logical wireless LANs. Only network cards that have the same SSID can register with this wireless network.
- Suppress SSID broadcastYou can operate your wireless LAN either in public or private mode. A wireless LAN in public mode can be contacted by any mobile station in the area. Your wireless LAN is put into private mode by activating the closed network function. In this operation mode, mobile stations that do not know the network name (SSID) are excluded from taking part in the wireless LAN.
With the closed-network mode activated, WLAN clients that use an empty SSID or the SSID "ANY" are prevented from associating with your network.
The option Suppress SSID broadcast provides the following settings:
- No: The access point publishes the SSID of the cell. When a client sends a probe request with an empty or incorrect SSID, the access point responds with the SSID of the radio cell (public WLAN).
- Yes: The access point does not publish the SSID of the cell. When a client sends a probe request with an empty SSID, the device similarly responds with an empty SSID.
- Tightened: The access point does not publish the SSID of the cell. When a client sends a probe request with a blank or incorrect SSID, the device does not respond.
Note: Simply suppressing the SSID broadcast does not provide adequate protection: When legitimate WLAN clients associate with the access point, this transmits the SSID in plain text so that it is briefly visible to all clients in the WLAN network. - MAC filter enabled
The MAC addresses of the clients that are allowed to associate with an access point are stored in the MAC filter list (). The MAC filter enabled switch allows you to switch off the use of the MAC filter list for individual logical networks.
Note: Use of the MAC filter list is required for logical networks in which the clients register via LEPS with an individual passphrase. The passphrase used by LEPS is also entered into the MAC filter list. The access point always consults the MAC filter list for registrations with an individual passphrase, even if this option is deactivated here.
- Maximum number of clientsHere you set the maximum number of clients that may associate with this access point. Additional clients wanting to associate will be rejected by the access point.
- Minimum client signal strengthThis value sets the threshold value in percent for the minimum signal strength for clients when logging on. If the client's signal strength is below this value, the access point stops sending probe responses and discards the client's requests. A client with poor signal strength will not detect the access point and cannot associate with it. This ensures that the client has an optimized list of available access points, as those offering only a weak connection at the client's current position are not listed.
- Client-bridge supportEnable this option for an access point if you have enabled the client-bridge support for a client station in WLAN client mode ().
Note: The client-bridge mode operates between two LANCOM devices only.
- Allow traffic between stations of this SSIDCheck this option if all stations logged on to this SSID are to be able to communicate with one another.
- (U)APSD / WMM Power Save activatedEnable this option to signal stations that the power saving function (U)APSD ([Unscheduled] Automatic Power Save Delivery) is supported. (U)APSD is established in the 802.11e standard, and helps VoWLAN devices to increase their battery life. The related devices switch to power saving mode after login on a (U)APSD-capable access point. If the access point receives data packets for the related devices thereafter, it temporarily stores the data and waits until the VoWLAN device is available again. It then forwards the data. Afterwards, (U)APSD increases the latency time of the radio module, whereby it ultimately consumes less power. The individual rest periods may be so short that a VoWLAN device can still use the power saving function in the call state itself. However, the relevant devices must also support (U)APSD. WWM (Wi-Fi Multimedia) Power Save is a power saving function of the Wi-Fi Alliance and is based on U-APSD. Certain LANCOM access points are WMM® Power Save CERTIFIED by the Wi-Fi Alliance.
- Only transmit unicasts, suppress broadcast and multicastsMulticast and broadcast transmissions within a WLAN cell cause a load on the bandwidth of the cell, especially since the WLAN clients often do not know how to handle these transmissions. The access point already intercepts a large part of the multicast and broadcast transmissions in the cell with ARP spoofing. With the restriction to unicast transmissions it filters out unnecessary IPv4 broadcasts from the requests, such as Bonjour or NetBIOS. The suppression of multicast and broadcast transmissions is also a requirement from the HotSpot 2.0 specification.
