Организация Wi-Fi-системы
With Netcraze routers, it is possible to set up Mesh Wi-Fi System with centralised management and monitoring.

Let's say you already have one Netcraze device working as a standalone router, and you want to expand your Wi-Fi coverage. Make your router the Main Router with the Wi-Fi System Controller functionality and add another Netcraze device (as a Wi-FI range extender) to your network by connecting it to the router via Ethernet cable or wireless Mesh Wi-Fi technology. You can add as many extenders to your network as you like.
Важно
To get the best performance from your Wi-Fi System, connect extenders over Ethernet.
Примечание
Wi-Fi System Controller functionality is supported by all current Netcraze models (with KN-XXXX index) from Starter to Titan except Buddy models, which work in Extender Mode only.
Any Netcraze model supports Extender Mode.
We recommend using the same version of the NDMS operating system on the main router and extenders to ensure the correct operation of the Wi-Fi System.
Важно
Configure the Wi-Fi seamless roaming settings before enabling the Wi-Fi System and connecting extenders to the Controller. These settings will automatically be applied to the extenders once the Wi-Fi System is switched on.
В настройках бесшовного роуминга рекомендуем включить 802.11r для обоих диапазонов 2.4 и 5 ГГц, 802.11kv и в параметрах Band Steering установить Предпочитать 5 ГГц. Как правило, указанные параметры являются самыми оптимальными и универсальными для работы большинства современных беспроводных устройств.
For Wi-Fi System to work, the Wi-Fi System controller component must be installed on the main router. You can check it on the General System Settings page in the NDMS Update and Component Options by clicking on Component options.
This component does not need to be installed on Extenders.
Set the operating mode switch to Extender or enable this mode in its web interface on the router you want to turn into Extender. Then connect the Extender to the main router using the included Ethernet cable. Use any free network port on the Extender.
Важно
An Extender connected via cable must be connected to the network port of the controller that belongs to the Home network.
Plug the Extender into the mains using the supplied power adapter. Make sure that the 
(Internet) LED on the device to be connected is lit steadily.

The Controller function is to be configured in the web configurator on the Mesh Wi-Fi System page. Once connected, the Extender will appear on the Devices tab in the Nodes available for adding to the Wi-Fi system list.
Важно
Before adding a new device to the Wi-Fi System, perform a factory reset on the Extender using the Reset button on the device's body.
The Controller will automatically detect the version of the Extender operating system and, if there is an update, will install the latest version of the device operating system. Click the Acquire button to add the Extender to the Wi-Fi System. Wait for the process to complete.
After a capture, the device will appear in the list of Extenders.
Подсказка
If for some reason, the Extender does not appear in the list of available to add or is not captured in the Wi-Fi System, we recommend that you perform a factory reset on it and then reconnect and catch.
After adding Extender to the Wi-Fi System, you can access its web interface. Click on the Extender's IP address link.
Важно
When connecting to the Extender interface, use the administrator account password set on the Controller.
You can only use the built-in administrator account to manage the Wi-Fi System — admin.

When you connect to the web interface of the Extender, you will see the message This device is administered by the Wi-Fi System controller.
Важно
On the Extender, the basic wireless network settings — Network name (SSID), Network protection (security protocol), Password (security key), seamless roaming settings, number of the wireless channel (if the Extender is connected by Mesh Wi-Fi technology), IP parameters, access control lists (White / Black) will not be available for editing. They can be changed only on the Wi-Fi System Controller (Main Router).
On the Mesh Wi-Fi System page, the Devices tab displays all Extenders – new, available for addition, and previously captured, already part of the Wi-Fi System.
Подсказка
By default, the Wi-Fi System Extenders are assigned a random IP address from the Controller, but you can manually set a specific fixed address if necessary. This is shown in the instructions Назначение постоянного IP-адреса на ретрансляторах Wi-Fi-системы.
The Transition Log tab displays transitions of wireless devices between the Wi-Fi System members. The following events are registered:
Подключение;
Отключение;
Переход (стандартный переход без "ускорителей", клиент просто отключился от одной точки и подключился к другой);
Переход по PMK-кэшу (быстрый переход с использованием PMKID-кэша, идентификатора спаренных мастер-ключей Pairwise Master Key Identifier);
Быстрый переход (самый быстрый переход с 802.11r и режимом FT — Fast Transition).
Когда в журнале переходов много записей, можно воспользоваться фильтром.

Важно
If an intermediate switch is used to connect Extenders, it must pass traffic completely transparently at the L2 level. The Wi-Fi System uses the STP protocol, and if the switch has MSTP / RSTP / STP support, these settings must be disabled on the ports used for the Wi-Fi System. But some switches (e.g. SNR, Zyxel) may then discard BPDU packets. In such cases, you need to configure STP on the switch, giving it the lowest priority in the topology not to claim to be the root node.
Подсказка
Starting with NDMS 4.1, the command mws stp priority has been added to allow you to STP bridge priority value a controller. It must necessarily become the root node in STP and to work seamlessly on an existing network with managed switches. Command example:
mws stp priority 16384 system configuration save
