MikroTik equipment configuration is made through the program called Winbox. You can download it via the link: http: //router_address/winbox/winbox.exe (where router_address is device address, respectively). Also you can go to the device through the web interface and download winbox through the link. The first thing we do - reset factory settings.
1. If you are connected to the device for the first time, the corresponding window titled RouterOS Default Configuration will appear immediately and you need to reset the settings by clicking on Remove Configuration.
2. If you have already visited the device once, the default window won’t appear. Go to the New Terminal menu and with the system reset-configuration command restart the device (after reboot window with settings reset will appear).
Or go to the System menu, then - into Reset Configuration. Then tick No Default Configuration and click on Reset Configuration. Factory configuration had reset.
Adding ports so the traffic can be transmitted through MikroTik equipment on a wired and WiFi interface. Otherwise, our devices will only talk to each other. To do this, click + button in the Bridge menu (opens a window like in the image below), assign name for the bridge and click OK.
Go to the Ports tab, click on + and add the Wlan1 port on Interface line. On the Bridge line chose our previously createdbridge1. Hit OK. Click + again and create Ether1port:
Assign IP-address for the bridge:
IPmenu => Adresses submenu => + button, enter bridge address and subnet mask. Filling lines after Network is optional.
Select Wireless, then open Wlan1.
Wireless interface parameters are set here:
Mode - Now we are interested in:
There is also a mode for client workstations:
Band - The first part of the value, up to a dash - is the frequency of operation, the second - supported standards. For the standards it is recommended to select only-N value, to raise the maximum speed.
On the client device, you can choose several options for standards, for example, expose 2GHz-B / G / N, then when you change settings on the BS customers you will reconnect automatically.
Channel Width - By default, put 20MHz. If you plan more than 100 Mbit / s and using Gigabit device - then you can use a 40MHz bandwidth.
Frequency - Select from the list or write manually.
SSID - The network name. It will be seen by the subscriber units.
Radio Name - The device name. For example, kv_Titova_d_8.
Scan List - Default, while using only the standard channels. You can specify a single frequency, multiple (separated by a comma), the range (with a dash), and can be combined. For example, a value of 2424, 2300-2500 will mean that the first device will start searching for the BS on the channel in 2424, in the absence of a response will go to the range 2300-2500, and will be looking there.
Wireless Protocol - equipment working protocols.
Security Profile - Normally - default.
Frequency Mode - Selection Mode for available frequencies and capacities
Country - Select a country to determine the list of frequencies that it is available.
Antenna Gain - Often not used, put 0 in field.
WMM Support< b> - Radio priorities.
Bridge Mode - Always - enabled.
Default Authenticate - When exposed tick – all devices can connect, tick removed - only those that are in the Allow list.
Default Forward - Exposed tick - restriction of data exchange between the connected client devices. This setting only works in 802.11 mode for laptops and devices without WDS support.
Hide SSID Exposed tick hides the name of the network (the network does not appear in the list if scanned). To connect, you must manually register the name of the client device.
If we choose N-only mode for our devices, all the checkboxes on this tab will be removed. Other - see settings below.
Rate Selection - Put the Advanced for our best configuration for devices.
Supported Rates - remove the ticks so devices will be using only a high-speed standard G and N.
Supported Rates A / G Expose all ticks.
Basic Rates B - remove all ticks.
Basic Rates A / G - Install only 6 M.
Max Station Count - The maximum number of client connections
Distance - The maximum distance to the subscriber stations
Noise Floor Threshold - The most common values are set ... -92 -107. You can also define it by yourself: to measure the noise level and reduce this figure by 5-10 units. For example: If the sound level -107, therefore, the value we put is -100.
Periodic Calibration - It is recommended to always include this option (enabled), so the device will automatically adjust to increase / decrease the noise level.
Calibration Interval - recommended to set for 10 seconds. Default is 1 minute.
Hw. Retries - The amount of data sent repeats unless the acknowledgment of receipt.
On this basis, for the base station preferably exhibit average values (5-7) and put the maximum channel-to-point - 15.
Hw. Protection Mode - Always put out RTS / CTS.
Adaptive Noise Immunity - It is recommended to activate the option AP and client mode for protection against interference when multiple base stations are close by.
Disconnect Timeout - The time period over which the client does not respond to the request, it will be disabled.
On Fail Retry Time - It is recommended to leave the 100 ms.
If our devices use MIMO (which is desirable since such equipment bandwidth is higher), then you need to pay attention to the appropriate setting antennas on the HTtab:
On the HT MCS tab it is recommended to leave the default values.
On the WDS tab we are interested in two parameters:
Here we set the parameters of the MikroTik NV2 protocol (by the way, setting NSTREME Protocol and the relevant tab we do not consider because it is outdated and almost never used).
More often is set to Default. If you select Manual, the field with the settings will appear and you can manually adjust radio card power.
In the Wireless section, go to Security Profiles tab:
Most of the settings are identical, with the exception of:
If we set up all correctly, you can see parameters in the Status tab:
Band - The frequency and standard of work points (Mode)
Frequency - The channel frequency of the device
Tx/Rx Rate - transmission and reception modulation
SSID - network name
BSSID - second device Mac address
Radio Name - second device name
Tx/Rx Signal Strenght - Signal level transmit / receive. If two antennas are used, the data is summed.
Tx/Rx Signal Strenght Ch0 - Signal level transmit / receive on zero antenna (channel)
Tx/Rx Signal Strenght Ch1 - Signal level transmit / receive on first antenna (channel)
Noise Floor - Noise level
Signal To Noise - the signal to noise ratio. Standard considered that values from 5 to 15 - low, 15 to 30 – average, 30 to 60 - high. Higher the value in this field - better.
Tx/Rx CCQ - channel transmit / receive quality.
Distance - The distance to the second device
Router OS Version - Firmware version of the second device
Last IP - Last IP-address recorded in the device
WDS Link - Shows the work in WDS.
