The Wireless section of the Network tab can be used to manage and configure WiFi Access Points and WiFi Stations (clients) . This chapter of the user manual provides an overview of the Wireless section for RUT900 devices. If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Basic" button under "Mode", which is located at the top-right corner of the WebUI.
RUT900 devices support IEEE 802.11b/g/n and 802.11e_WMM wireless technologies.
WiFi 2.4 GHz
The WiFi 2.4 GHz section is used to configure your wireless access points (AP) and wireless clients (STA).
Above is the overview of the Wireless Overview window. It displays active access pointsand stations. Here you can turn on or off your WiFi interfaces, remove them or start configuring by clicking on Edit button on the right side of interface. You can also configure your WiFi devices by clicking Edit button in the right side of each table header. To configure your Wireless device as Client press Scan button to scan the surrounding area and attempt to connect to a new wireless access point.
The Global Settings section is used for configuring WiFi hardware parameters. You can find this section by clicking the 'Edit' button next to a wireless device (not an interface) in the Network → Wireless page:
The General Setup section is used to turn a wireless device on or off, select the operating frequency (WiFi mode and channel), transmit power and define a country code.
A wireless 2.4 GHz WiFi channel requires a signaling band roughly 22 MHz wide, radio frequencies of neighboring channels numbers significantly overlap each other. Choose a WiFi channel according to the busyness of other channels. You can download a free WiFi analyzer app on your phone, laptop or other WiFi device and check which channel is the least populated.
Many home networks utilize routers that by default run on channel 6 on the 2.4 GHz band. Neighboring WiFi home networks that run over the same channel generate radio interference that can cause significant network performance slowdowns for users. Reconfiguring a network to run on a different wireless channel helps minimize these slowdowns. Therefore, pick a channel with no other active Access Points and preferably one that has no active Access Point on two adjacent channels on each side as well. If you don't feel like doing this, set the 'Channel' field to Auto and the device will pick the least busy channel in your location automatically.
|Enable||off | on; default: on||Turns Wireless device on or off.|
|Operating Frequency (2.4 GHz)|
|Mode||N | Legacy; default: N||Wireless N (802.11n) supports a maximum theoretical transfer rate of 300mbps with 2 antennas. It can reach up to 450 Mbps with 3 antennas. Though typical speeds are more accurately around 130 Mbps. The legacy standards include 802.11a, 802.11b, and 802.11g.|
|Channel||Auto | 1 (2412 MHz) | 2 (2417 MHz) | 3 (2422 MHz) | 4 (2427 MHz) | 5 (2432 MHz) | 6 (2437 MHz) | 7 (2442 MHz) | 8 (2447 MHz) | 9 (2452 MHz) | 10 (2457 MHz) | 11 (2462 MHz); default: Auto||A wireless 2.4 GHz WiFi channel requires a signaling band roughly 22 MHz wide, radio frequencies of neighboring channels numbers significantly overlap each other. Therefore, pick a channel with no other active Access Points and preferably one that has no active Access Point on two adjacent channels on each side as well.|
|Width||20 MHz | 40 MHz; default: 20 MHz||A 40 MHz channel width bonds two 20 MHz channels together, forming a 40 MHz channel width; therefore, it allows for greater speed and faster transfer rates. But not if those channels are crowded with noise and interference. In crowded areas with a lot of frequency noise and interference, a single 20MHz channel will be more stable. 40MHz channel width allows for greater speed and faster transfer rates but it doesn’t perform as well in crowded areas.|
|Transmit Power||[5%...100%]; default: 100 %||The transmit power of an access point radio is proportional to its effective range – the higher the transmit power, the more distance that a signal can travel, and/or the more physical materials that it can effectively penetrate and still have data successfully resolved at the receiver.|
|Country code||country code; default: US - United States||SO/IEC 3166 alpha2 country codes as defined in ISO 3166-1 standard.|
The Advanced Settings section is used to configure how the wireless Access Point will work from a hardware perspective.
|Operating Frequency (2.4 GHz)|
|Allow legacy 802.11b rates||off | on; default: on||Turn on to enable connections that uses legacy 802.11b standard.|
|Distance Optimization||integer [0..65535]; default: none||HT Distance to farthest network member in meters.|
|Fragmentation threshold||integer [256..2346]; default: none||The smallest packet size that can be fragmented and transmitted by multiple frames. In areas were interference is a problem, setting a lower fragment threshold might help reduce the probability of unsuccessful packet transfers, thus increasing speed|
|RTS/CTS threshold||integer [0..2347]; default: none||RTS/CTS (Request to Send/Clear to Send) are mechanisms, used to reduce frame collisions introduced by the hidden node problem. It can help resolve problems arising when several access points are in the same area, contending|
|Force 40MHz mode||off | on; default: off||Always use 40MHz channels even if the secondary channel overlaps. Using this option does not comply with IEEE 802.11n-2009!|
|Beacon interval||integer [15..65535]; default: none||Beacon signal interval in seconds.|
The WiFi Scanner provides you with the possibility to scan and collect information about connected devices and surrounding access points. The collected data is sent using the Data to Server functionality with Kinesis argument.
Note: WiFi Scanner is additional software that can be installed from the Services → Package Manager page.
|Enable||off | on; default: off||Enables or disables WiFi scanner.|
|Interval||integer; default: 10||Interval between scans in seconds.|
The Interface Configuration section is used to configure the parameters of Wireless Access Pointsor Clients. You can find this section by clicking the 'Edit' button next to a wireless device (not an interface) in the Network → Wireless page:
The General Setup tab contains basic options for ESSID and network interface.
|ESSID||Factory ESSID is different for every device; default: none||Extended Service Set Identifier.|

|MAC-List||MAC; default: none||List of MAC addresses to be included or excluded from connecting to your Wireless Access Point.|
|Isolate Clients||off | on; default: off||Prevents client to client communication on the same subnet.|
|Short Preamble||off | on; default: on||Uses Short Preamble, it uses shorter data strings that adds less data to transmit the error redundancy check which means that it is much faster.|
|DTIM interval||seconds; default: none||Delivery Traffic Indication Message Interval.|
|Time interval for rekeying GTK||seconds; default: none||Period of time in between automatic changes of the group key, which all devices on the network share.|
|Disable Inactivity Polling||off | on; default: off||Inactivity polling can be disabled to disconnect stations based on inactivity timeout so that idle stations are more likely to be disconnected even if they are still in range of the AP.|
|Station inactivity limit||seconds; default: none||Station inactivity limit in seconds. If a station/client does not send anything in st time frame, an empty data frame is sent to it in order to verify whether it is still in range. If this frame is not acknowledged, the station will be disassociated and then deauthenticated.|
|Maximum allowed Listen Interval||positive integer; default: none||Association will be refused if a client/station attempts to associate with a listen interval greater than this value.|
|Disassociate On Low Acknowledgement||off | on; default: on||Allow AP mode to disconnect stations/clients based on low Acknowledgement condition.|
RUT900 can also work as a WiFi client. Configuring client mode is nearly identical to Access Point, except for the fact that most of the options are dictated by the WiFi Access Point that the router is connecting to. Changing them can result in an interrupted connection to that router.
To begin configuring WiFi Client first click the 'Scan' button to scan the surrounding area and attempt to connect to a new wireless access point.
After which you will be redirected to the window shown below, where you will see list of available WiFi Access Points in the area. Choose one according to your liking and press the Join Network button next to it.
You again will be redirected to following window, where you will need to enter WPA passphrase or other security password depending on AP that you are connecting to, name yours network (it will be name of your wireless WAN interface) and assign firewall rule.
Next window that opens will be Device Configuration. Values there, mostly, should be left unchanged to avoid connection problems, because they are dictated by Access Point. Other than that, only difference from Access Point settings are in Interface Configuration → General Setup section, where Mode is set to Client, and Network attached to this wireless interface is WAN instead of LAN
Click Save & Apply and if you configured correctly, you will have Wireless Client working.
RUT900 can also be configured as a mesh gateway or as a node (router) connecting to a mesh gateway.
When RUT900 is configured as mesh gateway it provides internet access to other mesh nodes. When configured as mesh node it acts as a mesh router which forwards traffic to and from mesh gateway. Nodes also connect other wireless devices to the network such as laptops and cellphones.
For complete wireless mesh network example please visit Wireless Mesh configuration example.
When configuring RUT900 as a mesh gateway internet connectivity is required.
To begin click the 'Add' button below of wireless interface in the Network → Wireless page:
In General Setup tab change Mode to Mesh, set Mesh ID (this number has to be the same in all nodes that connect to this wireless mesh network) and select desired Network which will be attached to the interface. Click Save & Apply.
Next navigate to Wireless Security tab and select WPA3-SAE encryption to add authentication layer. The password must match in all devices within the mesh network.
Lastly, in Advanced Settings tab enable Forward mesh peer traffic and set RSSI threshold for joining to -80. Leave the rest as set by default.
Click Save & Apply and if you configured correctly, you will have wireless mesh gateway ready.
Mesh node is configured the same way as mesh gateway. Node has to match gateway's wireless mesh interface configuration. Additionally, LAN interface has to be setup as DHCP client:
1. Access router‘s WebUI. Navigate to Network → Interfaces.
2. Press pencil icon on the right of the LAN interface.
3. Change Protocol to DHCP.
Click Save & Apply and If everything was setup correctly, mesh node should be ready use.
The Multi AP feature is used to configure access to multiple wireless access points from one page. To enter Multi AP configuration, click the 'Multi AP' button below other Wireless configurations:
Next, enter a name for the Multi AP network and assign a firewall zone (default: wan).
You may then start to configure General Settings for the Multi AP feature.
The General Settings section for Multi AP is used to turn it on or off and to change the frequency of scanning for WiFi APs.
|Enable||off | on; default: off||Turns Multi AP configuration on or off.|
|Scan Time (sec)||integer (30+); default: 60||Frequency (in seconds) of scans for WiFi access point availability.|
|Upload AP list||- (interactive button)||Uploads a list of access point configurations.|
You can either configure multiple access points from this page of the WebUI or you can upload a file with a list of access point configurations. The file should contains WiFi access point configuration options and values, which should be defined as option: value (for example, ssid: home_wifi). The SSID option is mandatory.
|SSID||string; default: none||SSID of an access point.|
|Key||string; default: none||Pre-shared key, a custom passphrase used for user authentication (at least 8 characters long).|
|Enable||off | on; default: off||Turns an access point configuration on or off.|
|Delete||- (interactive button)||Deletes the access point configuration next to the button.|
Option names in the file should be provided in lower case letters. AP list file example:
ssid: RUT_1 enable: 1 key: 12345678 ssid: RUT_2 enable: 0 key: 87654321
Once uploaded, the contents of the file should become visible in the Access Points list.
