BeamOS – Wireless

BEAM OS Logo

Summary

The Wireless section of the Network tab can be used to manage and configure WiFi Access Points (AP) and WiFi Stations (STA). This chapter is an overview of the Wireless section of BEAM routers.

Wireless technology

BEAM iSERIES routers support IEEE 802.11b/g/n and 802.11e_WMM wireless technologies.

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 Wi-Fi is configured as an active WAN interface (either main or backup).
Network wireless configuration
Above is the overview of the Wireless Configuration window. It displays active access points and stations. Here you can disable or enable your Wi-Fi interfaces, remove unwanted access points or stations or enter a configuration window for each Wi-Fi 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 Wi-Fi interface that you wish to configure.

Device Configuration

The Device Configuration section is used for configuring Wi-Fi hardware parameters.
General Setup

The General Setup tab is used 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 Wi-Fi 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 Wi-Fi 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.
Network wireless device advanced
Field Name
Value
Description
Mode
Auto | 802.11b | 802.11g | 802.11g+n; Default: 802.11g+n
Wireless protocol used. Different modes provide different wireless standard support which directly impacts the radio’s throughput performance
HT Mode
20 MHz | 40 MHz 2nd channel above; Default: 20 MHz
HT (High Throughput) mode allows you to specify channel width. 40 MHz bandwidth provides better performance but it overlaps 4 adjacent channels on each side, therefore, it might overlap with many other Access Points working in those channels. If that is the case, the router will switch back to 20 MHz mode automatically to reduce interference. 40 MHz is only available if the selected channel is not Auto
Country Code
country code; Default: 0 – World
SO/IEC 3166 alpha2 country codes as defined in ISO 3166-1 standard
Transmit power
100 % | 80 % | 60 % | 40 % | 20 %; Default: 100 %
WiFi signal power. Use lower power to reduce the router’s CPU usage
Fragmentation threshold
integer [256..2346]; Default: ” “
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: ” “
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

Interface Configuration

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 Wi-Fi interface. When other Wi-Fi capable computers or devices scan the area for Wi-Fi 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.

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 (Wi-Fi 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.

An algorithm for performing encryption or decryption
Key
string; Default: ” “

WPA-Enterprise (WPA-EAP, WPA2-EAP)
The Enterprise variants of WPA and WPA2 use a RADIUS server for authentication purposes instead of a password(s).

Wireless Station

The BEAM iSERIES can also work as a Wi-Fi client. Configuring client mode is nearly identical to AP, except for the fact that most of the options are dictated by the wireless access point that the router is connecting to. Changing them can result in an interrupted connection to that AP.

In addition to standard options you can also click the Scan button to rescan the surrounding area and attempt to connect to a new wireless access point.

Network wireless station step1
Pressing Start scan will initiate a scan for available Wi-Fi Access Points in the area. After the scan finishes, you will see a list of these Access points. Choose one according to your liking and press the Join Network button next to it.
