802.11g Wireless Gaming Adapter and Ethernet Bridge User Guide
The Status page displays the particular status of, amongst other informative details, the network you�re associated to, including the SSID name, what channel you�re broadcasting on, and what firmware version your are using.
Note: If the MAC address field displays a �Device not associated� message, this indicates your 5430 is not associated to your wireless network. If, however, the MAC address field displays a valid MAC address, this indicates that your 5430 is associated to your wireless network.
Wireless Menu Options
Use the Wireless menu to change your mode from Client to Ad Hoc Mode and enter a Network Name (SSID) or select a unique channel for Ad Hoc Mode. If you are not sure of the SSID of your network, use the Site Survey feature under Tools to locate a network near the 5430.
Security: Using a secure wireless network
A wireless network offers you the freedom to roam without the burden of cables but it also means that your data is accessible to anyone else in range of your wireless grid. If you are concerned about a neighbor or someone within range of your wireless network using your wireless connection for malicious activity, we strongly recommend that you enable wireless security to prevent unauthorized connection or someone from eavesdropping to listen in on your network traffic. Today, many wireless routers provide several mechanisms for securing a wireless network and it is recommended that you first enable security on your wireless router and then match the method you have selected on your clients.
USRobotics recommends any one or both of the following two methods:
WEP (Wired Equivalent Privacy)
Your 5430 supports 64-bit and 128-bit WEP security. If available on your wireless router, we recommend you enable the higher bit security. When you enable WEP, it uses a key to encrypt the data and this specifically formatted data can only be understood by another wireless device that knows of this key. Since both ends use the same key, any users who do not know the key cannot connect to your network and use your Internet connection.
MAC Address filtering
Many wireless routers provide a mechanism for creating a list of devices that can participate in your wireless network. Refer to your wireless router or access point�s documentation to learn if MAC Address filtering is supported.
Enabling security on your 5430
Enabling WEP
After you have obtained your network name (SSID configured on your wireless router or access point and its security settings), you can use the Security menu located on the Web User Interface pages to program your 5430 for WEP security.
If you select WEP, you have the option to enforce Shared Key Authentication (Forced) or let the 5430 send it only when a wireless router requests it (Open System).
It is important that you match the Network Keys with those of your wireless routers. If you have multiple Network Keys, you can enter up to four keys.
Note: Network Keys are case sensitive. When entering a Network Key, be sure you insert the key exactly as it appears in your wireless router or access point.
Wireless MAC Filtering
You can use MAC Address filtering to connect only to a specific wireless router or access point. You can add the MAC Address of your wireless router or access point and change the �Wireless MAC address filtering� field to Allow. In doing so, your 5430 will only �talk� to your wireless router or access point and cannot be accessed by other devices.
Advance Menu Options
Radio
Use the Radio menu to enable and disable wireless signal transmission. If you want to shut down the signal of your unit (disconnect from the wireless network), select Radio Off.
Channel
802.11b and 802.11g use channels to limit interference from other devices. If you are experiencing interference with another 2.4Ghz device such as a baby monitor, security alarm, or cordless phone, change the channel on your 5430 as well as your wireless router. The channel feature will be used mostly in Ad Hoc Mode. In Client Mode, the 5430 automatically switches the channel to match the one from the wireless router or access point.
54g Mode
If you are having difficulty connecting to an 802.11b wireless only router, try switching your 5430 to 802.11b only mode and do the same with your wireless router. This will ensure you are connecting to 802.11b devices only. Set the mode to 54g Auto for the widest compatibility. Set the mode to 54g Performance for the fastest performance among 54g certified equipment.
54g Protection
The 802.11g standards provide a protection method so 802.11g and 802.11b devices can co-exist in the same network without �speaking� at the same time. Do not disable 54g Protection if there is a possibility that a 802.11b device may need to use your wireless network. In Auto Mode, the wireless device will use RTS/CTS to improve 802.11g performance in mixed 802.11g/802.11b networks. Turn protection off to maximize 802.11g throughput under most conditions.
54g+ (Xpress)
54g+ is a technology that utilizes standards based on framebursting to achieve higher throughput. With 54g+ enabled, aggregate throughput (the sum of the individual throughput speeds of each client on the network) can improve by up to 25% in 802.11g only networks and up to 75% in mixed networks comprised of 802.11g and 802.11b equipment.
Rate
You may force a lower data rate if you are having trouble getting connected or losing data at a higher rate. It is important to know that some data rates belong only to one 802.11 standard but not the other which will force your 5430 to connect to only that network. 802.11g rates; 6, 9, 12, 18, 24, 36, 48, 54 Mbps 802.11b rates: 1, 2, 5.5, 11 Mbps
Basic Rate Set
You have the option of supporting all rates as listed in the Rate section above or using the 1, 2 Mbps rates which will support only older 802.11b implementations.
Fragmentation Threshold
This threshold is used to fragment packets which help improve performance in the presence of RF interference.
RTS Threshold (Request to Send Threshold)
The RTS threshold determines the packet size of a transmission and, through the use of an access point, helps control traffic flow.
DTIM Interval
The DTIM Interval sets the Wake-up interval for clients in power-saving mode.
Beacon Interval
A beacon is a packet of information that is sent from a connected device to all other devices where it announces its availability and readiness. A beacon interval is a period of time (sent with the beacon) before sending the beacon again. The beacon interval may be adjusted in milliseconds (ms).
Preamble Type
Preambles are a sequence of binary bits that help the receivers synchronize and ready for receipt of a data transmission. Some older wireless systems like 802.11b implementation use shorter preambles. If you are having difficulty connecting to an older 802.11b device, try using a short preamble. You can select short preamble on if the 54g mode is set to 802.11b Only in the 54g Mode field.
Changing Between Client and Ad Hoc Modes
To change between Client and Ad Hoc Modes, simply access the Web User Interface, select Setup, and follow the on-screen instructions as demonstrated in the graphics below:
Or, you can also switch between modes by selecting the Wireless tab, selecting the appropriate mode from the Wireless Mode field, and selecting Apply.
Upgrading Your Adapter
Download and place the firmware file to a local directory. Place the 5430 in Configuration Mode (insert a pin or paperclip to press the reset button momentarily — less than 2 seconds). Connect the Ethernet cable to your computer�s Ethernet port and release and renew your computer�s IP address (refer to the Accessing the 5430�s Web User Interface pages in this User Guide for more information). Launch an Internet browser and enter http://192.168.1.201 in the address line. Enter the username (the default username is admin) and the password (the default password is admin) to access the Web User Interface. Select the Tools tab. From the New Firmware line, select Browse and locate where the downloaded firmware file was placed. Select Upgrade to start the upgrade. It is important that you do not unplug the cable or interrupt the upgrade. Allow several minutes for the adapter to reboot after the upgrade.
Tools Menu Options
Site Survey will search for all networks (SSID) in range of the adapter and allow you to select one for association. In case the selected network uses encryption, you first need to setup encryption on your 5430 using the Security tab (refer to your wireless router or access point documentation for specific networking security information).
Use the Tools menu to change the 5430 login account, modify the 5430�s management IP address and subnet mask, and restore the 5430 to factory defaults.
Advanced Properties
The Advanced tab from the USRobotics Properties allows you to view and change the values of the available properties.
To access the Advanced tab:
- Windows Vista: Click Windows Start >Control Panel >Network and Internet > Network and Sharing Center >Manage Wireless Networks >Adapter Properties. In Wireless Network Connection Properties, click Configure. In the Network Adapter Properties, click the Advanced tab.

BSS PLCP Header
The BSS PLCP Header property is used to set the header type used for CCK rates. The type can be Long or Auto (short/long).
Auto (Short/Long) (default)
Long
Fragmentation Threshold
The maximum size in bytes at which packets are fragmented and transmitted a piece at a time instead of all at once. Available values range from 256 to 2346. The default value is 2346.
IBSS 54g Mode
IBSS 54g Mode is used to set the connection type in an ad hoc network. The following options are available:
54g — Auto (default)
54g — Performance
802.11b Only
IBSS 54g Protection Mode
A mechanism of prefixing each OFDM data frame with a request to send/clear to send (RTS/CTS) complimentary code keying (CCK) frame sequence. The duration fields of the RTS and CTS frames should allow the IEEE 802.11b node to correctly set its network allocation vector (NAV) and avoid collisions with the subsequent OFDM frames. As required for Wi-Fi®, protection mechanisms are enabled automatically whenever an IEEE 802.11b STA joins the BSS. If no IEEE 802.11b STA joins, then no protection mechanism is used and full IEEE 802.11g performance is attained.
Auto (default)
Disabled
IBSS Channel Number
The IBSS Channel Number property selects the independent basic service set (IBSS) channel number on which to operate when WZC is managing your wireless networks. The default setting is 11.
Locally Administered MAC Address
Locally Administered MAC Address is used to override the MAC address of the . The Locally Administered MAC Address is a user-defined MAC address that is used in place of the MAC address originally assigned to the network adapter. Every adapter in the network must have its own unique MAC address. This locally administered address consists of a 12-digit hexadecimal number.
Value Assigns a unique node address for the adapter.
Not Present (Default). Uses the factory-assigned node address on the adapter.
The appropriate assigned ranges and exceptions for the locally administered address include the following:
- The range is 00:00:00:00:00:01 to FF:FF:FF:FF:FF:FD.
- Do not use a multicast address (least significant bit of the high byte = 1).
- Do not use all 0s or all F’s.
Power Output
The power output property allows users to reduce the power output of the radio and therefore, the noise level, if excessive noise is a problem.
100% (default)
25%
50%
75%
Power Save Mode
Power Save Mode is used to put the enabled computer into the IEEE 802.11 Power Save mode. In Power Save mode, the radio is periodically powered down to conserve power. When the radio is in Power Save mode, packets are stored in the access point until the radio comes on. Power Save Fast allows full throughput with power savings.
Disabled
Enabled
Fast (default)
Rate
This property allows you to specify the rate (in Mbit/s) at which data is transmitted. The possible values are: 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36 48, and 54 . The default is set to Use best Rate. This setting automatically adjusts the transmission rate to the optimal rate based on the capabilities of the other wireless clients and access points.
Note: The default value for this property is set for maximum performance. Therefore, it is not recommended for home users to change the value. Only network administrators or technicians with wireless LAN experience should attempt to make any changes.
Roam Tendency
This property adjusts the roaming thresholds for the .
Aggressive Roams to wireless networks having a signal strength at least 10 dB greater than the current one.
Conservative Roams to wireless networks having a signal strength at least 30 dB greater than the current one.
Moderate (default) Roams to wireless networks having a signal strength at least 20 dB greater than the current one.
Roaming Decision
This property sets the behaviour of the when roaming among access points.
Default (default)
Optimize Bandwidth
Optimize Distance
RTS Threshold
RTS Threshold sets the maximum number of frames allowed in a data packet before the Request To Send/Clear To Send Handshake is used. When the RTS Threshold is exceeded, the adapter sends a Request To Send message to the access point prior to sending data. When the access point receives the the Request To Send message, it broadcasts a Clear To Send message. This message tells the requesting adapter to send its message while telling other adapters to refrain from sending data while the requesting adapter sends its message. In environments where there are frequent data collisions between wireless adapters, decreasing the RTS threshold can decrease collisions and improve network performance. However, each RTS/CTS handshake adds communication overhead that can decrease network performance.
The default value is 2347. The range is 0 to 2347.
WMM
Wi-Fi Multimedia (WMM™). The WMM property enables quality of service for audio, video, and voice applications over a wireless network by prioritizing streams of content and optimizing the way the network allocates bandwidth among competing applications.
Auto When the wireless client connects to the access point, and the access point has Unscheduled Automatic Power Save Delivery (UAPSD) enabled, the wireless client is allowed to enter Power Save mode.
Enabled (default) The wireless client enters Power Save mode for WMM associations independent of whether the access point has UAPSD enabled or disabled.
Disabled The wireless client does not have WMM association.
Режимы WiFi — a/b/g/n/ac/ax Стандарты в Работе Беспроводной Сети 2.4 и 5 ГГц — Что Это и Какой Выбрать?
Сегодня поговорим о понятии режимов сети WiFi (802.11). Наверняка при настройке роутера вы видели такой раздел, как «Беспроводной режим работы» с возможностью выбора между стандартами «a, b, g, n» для 2.4 ГГц и 5 ГГц. А в новых двухдиапазонных моделях к ним еще добавились смешанные режимы «ac и ax». Посмотрим, какой из них выбрать и где поменять в настройках роутера TP-Link, Zyxel Keenetic, Asus, Netis, Tenda, Upvel, Huawei и Mercusys
Что такое режимы работы WiFi на 2.4 и 5 ГГц — стандарты и скорость a/b/g/n/ac/ax
Для начала давайте разберемся, что же это такое за режимы wifi — a/b/g/n/ac/ax? По сути, эти буквы являются отображением этапов развития в скорости беспроводной сети. При появлении каждого нового стандарта вай-фай ему давали новое буквенное обозначение, которое характеризовало его максимальную скорость и поддерживаемые типы шифрования для защиты.
- 802.11a — самый первый стандарт WiFi, который работал в диапазоне частот 5 ГГц. Как это ни странно сегодня видеть, но максимальная поддерживаемая скорость составляла всего 54 МБит/c
- 802.11b — потом wifi захватил частоты на 2.4 ГГц и несколько последующих режимов работы поддерживали именно данный диапазон. В их числе «b», скорость на котором равнялась до 11 Мбит/c
- 802.11g — более современный вариант и именно на нем работал мой роутер, когда я написал самую первую статью на данном блоге wifika.ru. Однако, и он уже безвозвратно устарел, так как ограничение по скорости равно 54 МБит/c
- 802.11n — это уже вполне себе рабочий режим wifi для 2.4 ГГц, под который до сих пор выпускается огромное количество беспроводных устройств. Максимальная скорость равна 600 МБит/с при ширине канала в 40 МГц, что достаточно для большинства не требовательных к высокой скорости задач. Хотя бюджетные роутеры или адаптеры чаще всего имеют ограничение в 150 или 300 mbps из-за технических особенностей экономичного железа
- 802.11ac — также современный стандарт беспроводной связи для диапазона 5 ГГц, в котором работает большинство относительно недорогих двухдиапазонных маршрутизаторов и других девайсов. В зависимости от своих характеристик (поддержки MU-MIMO, количества антенн) такие устройства могут достигать скоростей в 6 ГБит/c, что уже более, чем достаточно для выполнения подавляющего списка задач, таких как онлайн игр или воспроизведения видео в высоком качестве
- 802.11ax — самое новое поколение wi-fi, которое принято называть WiFi 6. Умопомрачительные скорости, которые на сегодняшний день избыточны, но уже завтра возможно станут такими же обыденными, как b, g, n и ac. Гаджеты с поддержкой wifi 802.11ax стоят очень дорого, и те, кто их приобретают, точно знают, для чего им это нужно
Какой выбрать режим работы WiFi a, b, g или n для 2.4 ГГц?
При настройке wifi сети роутера в диапазоне частот 2.4 ГГц мы имеем возможность выбора между режимами b, g и n. Это необходимо для установки максимально возможной скорости интернет соединения. Однако, если выбрать самый современный «n», то можем получить такую ситуацию, при которой какое-нибудь старое устройство не сможет подключиться к wifi сети.
Стоит отметить, что все роутеры, адаптеры и прочее сетевое оборудование, которое поддерживает более новый режим wifi, полностью совместимы и со старыми. Если на коробке написано «Wi-Fi 802.11 AC» или «802.11 AX (WiFi 6)«, то на 100% устройство подойдет для любого wifi в сетях 2.4 и 5 ГГц.
Поэтому в настройках роутера помимо отдельных чаще всего мы имеем в меню режима такой пункт, как «смешанный (b,g,n)» или «mixed» в английской версии панели администратора. Он позволяет предоставить маршрутизатору выбор, какой из предложенных лучше всего подходит для того или иного устройства — ноутбука, смартфона, планшета, ТВ и т.д. Тем самым обеспечивается максимальная совместимость стандартов wifi для работы любого девайса.
Какой выбрать режим wifi в настройках роутера?
Александр ВайФайкин
специалист по беспроводным сетям
При настройке роутера рекомендуется выбирать именно смешанный режим для максимальной совместимости при поддержке самой высокой скорости
При этом скорость беспроводного сигнала и интернета, с которой будет работать устройство, определяется не параметрами, указанными в панели маршрутизатора, а техническими возможностями отдельной конкретной модели. Например, однодиапазонный (2.4 GHz) роутер с 1 антенной сможет предоставить максимально 150 МБит/c, с двумя — 300 и так далее до 600.
Какой режим работы установить для wifi 5 ГГц — ac или ax?
Вопрос выбора режима работы wifi для диапазона частот 5 ГГц стоит не так остро. Потому что вряд ли обычному пользователю интернета вообще когда-либо в руки попадался маршрутизатор с поддержкой стандарта «ax». Самым ходовым сегодня является режим «ac», поэтому в большинстве моделей даже выбора между ними не предлагается. Чаще всего мы можем видеть все тот же смешанный тип «802.11 A + n + ac»
Если же стандарт «AX» поддерживается, то опять же, логичнее выбирать именно смешанный тип для наилучшей совместимости стандартов wifi между всеми подключаемыми к роутеру компьютерами, ноутбуками, смартфонами и ТВ приставками.
Настройка стандарта wifi на Keenetic
Для указания режима wifi на роутере Keenetic необходимо в панели управления перейти в раздел «Домашняя сеть» и открыть ссылку «Дополнительные настройки»
Здесь в пункте «Стандарт» ставим на «802.11bgn», а ширину канала обозначаем как 40 МГц
