WLAN functionality

• The Wi-Fi is available in the devices "Black Dwarf", "RC100" and "RC200" from the time of delivery or as a retrofit kit.
• The devices/retrofit kits can only be obtained from Securepoint GmbH or Wortmann AG.

Foreign products are not supported.

• Detailed instructions for retrofitting can be found here.
  

Attention: This WiFi setup guide is not a bridge configuration. The Wi-Fi IP circle must be in an independent subnet.
As with any DMZ, rules and HideNATs may need to be created to allow access to the Internet/local network.
If a bridge is to be set up in which the Wi-Fi and the internal network are in the same IP network, the corresponding Instructions for Bridging must be used.

Call up the Wi-Fi configuration in the → Network →Network configurationTab WLAN menu.

Setup
Operation mode:	802.11g	Sets the speed and, if necessary, the frequency of the transmission.
	Operation mode: Description: 802.11a 54 MBit/s, 5 GHz 802.11b 11 Mbit/s, 2,4 GHz 802.11g 54 MBit/s, 2,4 GHz 802.11an 802.11n with up to 300 MBit/s, 5GHz Depending on the settings of the HT Capabilities of the client    802.11gn 802.11n with up to 300 MBit/s, 2,4GHz Depending on the settings of the HT Capabilities of the client
Country code:	DE	The country code is used to determine which frequencies and which signal strength may be used. Die genutzten Frequenzen und die Sendeleistung lassen sich in einem Wikipedia-Artikel nachlesen.
Channel:	AUTO	The channel can be set individually or selected automatically, depending on the mode.
Save		Saves the settings and closes the input dialogue.
Print WLAN QR codes Print WLAN QR codes		Creates an html page with access codes in QR format for the WLANs and opens the print dialogue of the browser.
WLAN Wizard Add WLAN		Opens the Wi-Fi wizard Depending on the WLAN hardware available, up to 4 WLANs may be possible.
Step 1 - IP address Step 1 - IP address
BSS:	wlan0	Interface Name - is predefined and cannot be changed. (is part of the Basic service Set)
IP address:	192.168.177.1/24	IP address of the Wi-Fi interface. The address of the interface also automatically determines the network used for the WLAN. The network selected for the WLAN (in this case 192.168.177.0/24) must under no circumstances match any other network on the appliance!
Step 2 - SSID Step 2 - SSID
Network Name (SSID):	TTT-Point-WLAN	The name of the network with which the WLAN is displayed on other devices.
SSID-Broadcast:	On	When activated, the WLAN is displayed for other devices.
Step 3 - Authentication Step 3 - Authentication
Security Mode:	WPA	Considered unsafe and only present for backwards compatibility.
	WPA2	Standard with increased safety
	WPA3 from v12	Standard with highest available safety.
Management Mode:	PSK	Pre Shared Key. The base station and mobile device must have the same PSK (≙password). The security of the encryption depends directly on the length and complexity of the PSK! Short or easily guessed PSKs jeopardise network security. A secure PSK is automatically suggested, which can be regenerated with .
	SAE	Simultaneous Authentication of Equals: (Only with WPA3) . Also uses a PSK, but uses an improved method for key exchange. A unique but different Pairwise Master Key (PMK) is derived from the password for each client. Despite the use of a password that is the same for all clients, each client receives its own PMK. Pairwise Transient Keys (PTK) are derived from the PMK by means of a four-way handshake between the WiFi client and the authentication server.
	EAP	Extensible Authentication Protocol / WPA Enterprise: Authentication via a Radius Server. (This is set under → Authentication →Radius Authentication).
	OWE	Opportunistic Wireless Encryption: Encrypted connections without a password. Can be used for the Captive Portal, for example.
Step 4 - Zones Step 4 - Zones
New Zone:	On	Creates a new zone for the Wi-Fi. Each Wi-Fi needs its own zone. A separate zone (with its own port filter rules) can be created for each WLAN
Auto-generate rules:	On	Creates a port filter rule set for this interface with {spc any These are only used to temporarily put the network into operation and should definitely be replaced by dedicated port filter rules! (Menu → Firewall →Portfilter) If the transparent mode of the HTTP proxy is to be used, this must also be configured: → Applications →HTTP ProxyTab Transparent Mode Button Add Transparent Rule
Generate DHCP Pool:	On	Creates a DHCP pool with the selected network and the interface IP al router address. Edit in the DHCP Pools tab.
Finish	Completing the wizard and saving the settings
Edit WLAN settings Edit WLAN settings
Tab General
BSS	Anyideas	Interface Name - is predefined and cannot be changed. (is part of the Basic service Set)	List of configured WLANs (max. 2) Depending on the WLAN hardware available, up to 4 WLANs may be possible.
Network Name (SSID)	TTT-Point-WLAN	The name of the network with which the WLAN is displayed on other devices.
SSID-Broadcast	On	When activated, the WLAN is displayed for other devices.
Tab Authentication
Settings as in wizard step 3 Additionally for WPA or WPA2:
Encryption:	CCMP	Encryption protocol based on the Advanced Encryption Standard (AES). A 128-bit key with a 48-bit initialisation vector is used.
	TKIP	Uses simple encryption. Use is strongly discouraged! Not available when using WPA3.
Tab Options
AP Isolate:	On	End devices can only reach the firewall in the WLAN network. Clients in the same WLAN network cannot reach each other.
Wi-Fi Multimedia (WMM):	On	End devices can tag their frames, which affects the priority.
Management Frame Protection (MFP):	Deaktiviert Optional Erforderlich	Enables encryption of the communication for the establishment and operation of the data connection according to IEEE 802.11w Increases network security and prevents e.g. Man in the Middle attacks. Requires WPA2 or WPA3
WPA Group Rekeying:	600(default)	The entered value indicates the time interval in seconds by which the encryption is renegotiated.
Beacon-Interval::	100(default)	Frequency in ms with which the base station transmits general information and management packets with identification data, to inform about its presence In fact, the value given is kμs (kilomicroseconds). One kμs corresponds to 1.024 milliseconds or 0.001024 seconds
