RUTX11 Wireless

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 is an overview of the Wireless section of RUTX11 routers.

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.

Wireless technology #

RUTX11 routers support IEEE 802.11ac (WiFi 5) with data transmission rates up to 867 Mbps (Dual Band, MU-MIMO), 802.11r fast transition.

Wireless Overview #

The Wireless Overview window provides you with the possibility to configure your wireless access points and wireless clients in both, 2.4GHz and 5GHz, bands.

Networking rutxxx manual wireless overview window v2.png

Above is the overview of the Wireless Overview window. It displays active access points and 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 under chosen band (2.4 GHZ or 5 GHZ) to scan the surrounding area and attempt to connect to a new wireless access point.

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 Wireless device for specific radio band, select the operating frequency and transmit power. Transmit Power.

Choose a WiFi channel according to the busyness of other channels. While RUTX11 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 and check which channel is least used. RUTX11 routers WiFi works on the 2.4 GHz and 5 GHz bands. 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.

Field NameValueDescription
Enableoff | on; default: onToggle Wireless device on or off.
Operating Frequency (2.4 GHz)
ModeN | Legacy; default: NWireless N (802.11n) supports a maximum theoretical transfer rate of 300mbps with 2 antennas. It can reach up to 450mbps with 3 antennas. Though typical speeds are more accurately around 130mbps. The legacy standards include 802.11a, 802.11b, and 802.11g
ChannelAuto | 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: 11(2462 MHz)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.
Width20 MHz | 40MHz; default: 20MHZA 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.
Operating Frequency (5 GHz)
ModeN | AC; default: ACChoose between 802.11n and 802.11ac standards.
ChannelAuto | 36(5180 MHz) | 40(5200 MHz) | 44(5220 MHz) | 48(5240 MHz) | 52(5260 MHz) | 56(5280 MHz) | 60(5300 MHz) | 64(5320 MHz) | 68(5340 MHz) | 72(5360 MHz) | 76(5380 MHz) | 80(5400 MHz) | 84(5420 MHz) | 88(5440 MHz) | 92(5460 MHz) | 96(5480 MHz) | 100(5500 MHz) | 104(5520 MHz) | 108(5540 MHz) | 112(5560 MHz) | 116(5580 MHz) | 120(5600 MHz) | 124(5620 MHz) | 128(5640 MHz) | 132(5660 MHz) | 136(5680 MHz) | 140(5700 MHz) | 144 (5720 MHz) | 149 (5745 MHz) | 153 (5765 MHz) |157 (5785 MHz) | 161 (5805 MHz) | 165 (5825 MHz); default: 36(5180 MHz)A wireless 5 GHz WiFi channel also requires a signaling band roughly 22 MHz wide, but since its channel with is 20 MHZ ir overlaps less with neighboring channels, but it is still recommended to 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.
Width20 MHz | 40 MHz | 80 MHz; default: 80MHZA 40 MHz channel width bonds two 20 MHz channels together, forming a 40 MHz channel width, 8 MHZ channel bonds four 20 MHz cannels; 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. 80 MHz width channel is faster than 40MHz which is faster than 20 MHz 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 codecountry code; default: US – United StatesSO/IEC 3166 alpha2 country codes as defined in ISO 3166-1 standard.

Client Mode #

RUTX11 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 press Scan button under chosen band (2.4 GHZ or 5 GHZ) 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.
