Nv2 protocol is proprietary wireless protocol developed by MikroTik for use with Atheros TDMA media access technology solves hidden node problem and improves media usage, thus improving throughput and latency, especially in PtMP networks. Nv2 is supported for Atheros This means that both - 11n and legacy devices can participate in the same network and it is not required to upgrade hardware to implement Nv2 in network. Media access in Nv2 network is controlled by Nv2 Access Point.
Nv2 AP divides time in fixed size "periods" which are dynamically divided in downlink data sent from AP to clients and uplink data sent from clients to AP portions, based on queue state on AP and clients. Uplink time is further divided between connected clients based on their requirements for bandwidth.
At the begginning of each period AP broadcasts schedule that tells clients when they should transmit and the amount of time they can use. In order to allow new clients to connect, Nv2 AP periodically assigns uplink time for "unspecified" client - this time interval is then used by fresh client to initiate registration to AP. Then AP estimates propagation delay between AP and client and starts periodically scheduling uplink time for this client in order to complete registration and receive data from client.
Nv2 implements dynamic rate selection on per-client basis and ARQ for data transmissions. This enables reliable communications across Nv2 links.
Nv2 protocol is not compatible to or based on any other available wireless protocols or implementations, either TDMA based or any other kind. This implies that only Nv2 supporting and enabled devices can participate in Nv2 network.
Regular In the same way other networks may disturb Nv2 network, because every other signal is considered noise. As of version 5. This setting controls which wireless protocol selects and uses.
Note that meaning of this setting depends on interface role either it is AP or client that depends on interface mode setting. Find possible values of wireless-protocol and their meaning in table below.Zabbix docker monitoring
Note that wireless-protocol values Nv2-nstreme Using these values can help in migrating network to Nv2 protocol. The following settings are relevant to Nv2 AP:. Using wireless-protocol setting aids in migration or evaluating Nv2 protocol in existing networks really simple and reduce downtime as much as possible. These are the recommended steps:. This feature will let multiple MikroTik Nv2 APs on the same location to coexist in a better fashion by reducing the interference between each other.
That allows to reuse the same wireless frequency on the location for multiple APs giving more flexibility in frequency planning. QoS in Nv2 is implemented by means of variable number of priority queues. Queue is considered for transmission based on rule recommended by In practice this means that at first all frames from queue with higher priority will be sent, and only then next queue is considered. Therefore QoS policy must be designed with care so that higher priority queues do not make lower priority queues starve.
Nv2-queue-count parameter specifies number of priority queues used. Mapping of frames to queues is controlled by Nv2-qos parameter.We consider the scenario for wireless network, when only clients from User Manager database are able to establish communications with 'Access Point' router.
To make this setup, you must have running Access Point. Let us consider configuration steps for Access Point and User Manager routers.
Jump to: navigationsearch. Introduction We consider the scenario for wireless network, when only clients from User Manager database are able to establish communications with 'Access Point' router.
Note, first local router database is consulted, then User Manager database. Wireless client will be unable to connect to Access Point, if Access Points router does not contain any entry in the 'interface wireless access-list' for the particular configuration and User Manager server will not have any information about user's data. Note that when using a version 3. Navigation menu Personal tools Log in. Namespaces Page Discussion. Views Read View source View history.

You will see some wireless cards listed here, they might be disabled - to turn them on, click on the blue Enable button. Make sure that the interface is configured and the antennas are connected before you enable an interface.Cb test certificate
To configure an interface, double-click it's nameand the config window will appear. To set the device as an AP, choose " ap bridge " mode. Close the wireless setting window with OK if you are done, and move to the Security Profiles tab of the Wireless interface window. There, make a new profile with the Add button and set desired WPA2 settings.
You can choose this new security profile back in the Interface configuration. Just connecting is probaly not enough, as your AP needs an IP address. This can be configured in the IP menu. Make sure that your stations also have IP addresses from the same subnet, or set up a DHCP server in this Router not covered in this tutorial.
If your ISP doesn't know about your new local network and hasn't set up proper routes to it, you need to configure SRC-NAT so that your stations have access to the internet via their private IP addresses. They will be masqueraded by the router's NAT functionality not covered in this tutorial.

Navigation Main Page Recent changes. This page was last edited on 15 Marchat Sometimes it happens that router's configuration is changed in a way that will make the router inaccessible except from local console.
Usually this is done by accident, but there is no way to undo last change when connection to router is already cut. Safe mode can be used to minimize such risk.Kumkum bhagya 16 february episode
Safe mode is entered by pressing Ctrl-X. To exit without saving the made changes, hit Ctrl -D. Message Safe Mode taken is displayed and prompt changes to reflect that session is now in safe mode. In WinBox safe mode is enabled by toggling Safe Mode toggle button on the left side of the toolbar. All configuration changes that are made also from other login sessionswhile router is in safe mode, are automatically undone if safe mode session terminates abnormally.

You can see all such changes that will be automatically undone tagged with an F flag in system history:. If too many changes are made while in safe mode, and there's no room in history to hold them all currently history keeps up to most recent actionsthen session is automatically put out of the safe mode, no changes are automatically undone.
Thus, it is best to change configuration in small steps, while in safe mode. Pressing Ctrl - X twice is an easy way to empty safe mode action list.
System backup is the way to completely clone routers configuration in binary format. Backup file contains not just configuration, but also statistics data, logs etc. The backup file is best used to save and restore configuration on the same device, for moving configuration to other devices, use export files instead.
Backup files contain sensitive information passwords, keys, certificates. File can be encrypted, but even then backups should be stored only in secure location. Restoring backup file should be done only on the same router or on the similar router, when previous router fails. Backup must not be used to clone configuration on multiple network routers. RouterOS allows to export and import parts of configuration in plain text format.
This method can be used to copy bits of configuration between different devices, for example clone whole firewall from one router to another.Mikrotik Wireless Basic Configuration
For example, Ipsec default policy will not be exported, and if we change one property then only our change will be exported:. Root menu command import allows to run configuration script from specified file. Script file with extension ". It is also possible to automatically execute scripts after upload to the router with FTP. This command clears all configuration of the router and sets it to the factory defaults including the login name and password 'admin' with empty password.
For more details on default configurations see the list. Backup file of existing configuration is stored before reset.But default configuration sometimes makes you confused. So, I always suggest to reset and remove default configuration.
The following steps will show how to reset and remove RouterOS default configuration. Now created SSID will be found in wireless devices and wireless device can be connected providing password. You will find connected devices in Registration tab. But connection is not enough to get internet. IP address, default gateway and other network parameters have to provide to get internet to the connected devices.
So, we will now do MikroTik Router basic configuration with creating bridge interface. The following steps will show how to create bridge interface and add physical interfaces to it. The following steps will show how to do basic configuration in MikroTik Wireless Router.Funny inappropriate sentences
Now connect any wireless device or connect any LAN device. The device will get IP address, default gateway and other network parameters automatically and be able to get internet access. I hope it will reduce your any confusion. I hope you will now be able to configure MikroTik Wireless Router following the above steps properly.
However, if you face any confusion to follow the above steps properly, feel free to discuss in comment or contact with me from Contact page. I will try my best to stay with you. Your name can also be listed here. Have an IT topic? Submit it here to become a System Zone author. This way you can easily adjust the Tx power output of your AP by adding the antena gain.Wireless features compatibility table for different wireless protocols.
Wireless can operate in several modes: client stationaccess point, wireless bridge etc. Client will connect to AP only if it supports all basic rates announced by the AP. Allowed values depend on selected band, and are restricted by country setting and wireless card capabilities.
This setting has no effect if interface is in any of station modes, or in wds-slave mode, or if DFS is active. Station modes :. Since RouterOS v6. If this value isstation will initially use MAC address of the wireless interface.
Access to registration-table also triggers update of these values. Frame protection helps to fight "hidden node" problem. There are several types of protection:. Protection mode is controlled by hw-protection-mode setting of wireless interface.
User Manager/Wireless Example
Frame size threshold at which protection should be used is controlled by hw-protection-threshold setting of wireless interface. For example, to enable "CTS-to-self" based frame protection on AP for all frames, not depending on size, use command:. See the Nv2 documentation: NV2. TDMA is a channel access method for shared medium networks.
It allows several users to share the same frequency channel by dividing the signal into different time slots. The users transmit in rapid succession, one after the other, each using his own time slot. This allows multiple stations to share the same transmission medium e. Starting from RouterOS v5.
