==Wireless Configuration==
 
The '''Wireless configuration''' window provides you with the possibility to configure your wireless access points and wireless stations. The Wireless Station Mode will become active only when WiFi is configured as an active WAN interface (either main or backup).

Above is the overview of the Wireless Configuration window. It displays active access points and stations. Here you can disable or enable your WiFi interfaces, remove unwanted access points or stations or enter a configuration window for each WiFi interface, where you can configure it more thoroughly.
 
==Wireless Access Point==
 
The Wireless Access Point configuration window is used to make changes to different access points. It is divided into two main sections – device and interface. One is dedicated to configuring hardware parameters, the other – software. To access this window, simply click the '''edit''' button next to the WiFi interface that you wish to configure:

===Device Configuration===
----
The '''Device Configuration''' section is used for configuring WiFi hardware parameters.
 
====General Setup====
----
The '''General Setup''' tab is used to '''Enable''' or '''Disable''' an Access Point and to select the wireless channel used by the Access Point.
 
Choose a WiFi channel according to the busyness of other channels. While RUT devices do not provide a function that lets you monitor the usage of nearby WiFi channels, you can download a free WiFi analyzer app on your phone, laptop or other WiFi device. In most countries there are 13 WiFi channels on the 2.4 GHz band (14 in Japan) to choose from. RUT routers' WiFi works on the 2.4 GHz band. 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. 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 router will pick the least busy channel in your location automatically.

====Advanced Setup====
----
The '''Advanced Setup''' tab is used to configure how the wireless Access Point will work from a hardware perspective.

The '''Interface Configuration''' section is used to configure wireless Access Points from the software perspective.
 
====General Setup====
----
The '''General Setup''' tab contains only two options. '''SSID''' is the name of your WiFi interface. When other WiFi capable computers or devices scan the area for WiFi networks they will see your network with this name. '''Hide SSID''' is used to make your Access Point invisible to other devices. To use a hidden WiFi Access Point, first un-hide it, connect your device to it, then hide it again.
 
[[Image:Network wireless interface general.PNG]]
 
====Wireless Security====
----
The '''Wireless Security''' tab is used to determine what kind of encryption your WLAN will use. You can choose between different types of '''WEP''' (Wireless Encryption Protocol) or '''WPA''' (WiFi Protected Access.) '''WPA''' provides better security because it uses improved data encryption through the temporal key integrity protocol (TKIP) but not all devices support '''WPA''' and will work only with '''WEP''' type of encryption.

The information in this page is updated in accordance with firmware version RUT2_R_00.07.06.16.


Note: click here for the old style WebUI (FW version RUT2XX_R_00.01.14.7 and earlier) user manual page.

Summary

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 RUT240 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

RUT240 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.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.


Global Settings

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 → SSIDS page:

General Setup

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.

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

RUT240 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

RUT240 can also be configured as a mesh gateway or as a node (router) connecting to a mesh gateway.

When RUT240 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 RUT240 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.

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.


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.
