The information in this page is updated in accordance with firmware version RUT36X_R_00.07.10.2.

Summary

The Wireless section of the Network tab can be used to manage and configure WiFi Access Points, WiFi Stations (clients) and WiFi devices. This chapter of the user manual provides an overview of the Wireless section for RUT360 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 "Advanced" button, located at the top of the WebUI.

Wireless

RUT360 devices support IEEE 802.11b/g/n and 802.11e_WMM wireless technologies.

SSIDS

The SSIDs section is used to configure your wireless access points (AP) and wireless clients (STA).

Above is the overview of the SSIDS 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.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.

Radio

The Global Settings section is used for configuring the country code which is used for regulatory purposes (different areas allow different maximum transmit power and operating frequencies) and WiFi hardware parameters. You can change parameters by clicking the 'Edit' button next to a wireless device (not an interface) in the Network → SSIDS page:

Field	Value	Description
Country code	country code; default: US - United States	SO/IEC 3166 alpha2 country codes as defined in ISO 3166-1 standard.

General Setup

The General Setup section is used to turn a wireless device on or off, select the operating frequency (WiFi mode, channel and channel width) and transmit power.

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.

Field	Value	Description
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.

Advanced Settings

The Advanced Settings section is used to configure how the wireless Access Point will work from a hardware perspective.

Field	Value	Description
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.

Configuration examples

Client Mode

RUT360 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.

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 wifi1 instead of LAN

Click Save & Apply and if you configured correctly, you will have Wireless Client working.

Mesh Mode

RUT360 can also be configured as a mesh gateway or as a node (router) connecting to a mesh gateway.

When RUT360 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.

Mesh Gateway

When configuring RUT360 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

Mesh node is configured the same way as mesh gateway. Node has to match gateway's wireless mesh interface configuration. Additionally, WAN interface has to be setup as DHCP client:

1. Access router‘s WebUI. Navigate to Network → WAN.

2. Press edit button on the right of the WAN interface.

3. Change Protocol to DHCP and select necessary device . Click Save & Apply and If everything was setup correctly, mesh node should be ready use.

Multi AP

The Multi AP feature is used to configure access to multiple wireless access points from one page. To create Multi AP wireless interface click the 'Add' button below of wireless interface in the Network → Wireless page:

In General Setup tab change Mode to Multi AP, select desired Network which will be attached to the interface. You can also select scan time and upload file with Access Points list.

Access Points

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.

Field	Value	Description
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.

WiFi QR codes

Each WiFi interface has a specially designed QR code that contains information about the SSID and password of the WiFi network. After pressing the button , a QR code appears with the network's SSID and password, which you can download locally by pressing the 'Download' button. If you only want a QR code without additional information, uncheck the 'Include credentials' box.

Relay Configuration

The Relay Configuration section is used to relay and dynamically redirect incoming connections to a target host. Its main purpose is extending the wireless network. For example, when the device is in Wireless Station (client) mode, it can be used to bridge WAN and LAN interfaces to create a larger wireless network.
You can find a detailed usage example here.

Note: Relay is additional software that can be installed from the System → Package Manager page.

Field	Value	Description
Enabled	off \| on; default: off	Turns the relay configuration on or off.
Interface	network interface; default: none	Network interface associated with the wireless interface.
Wireless interface	network interface; default: none	Wireless interface associated with the relay configuration.
