Many users of the equipment Mikrotik Many people face a situation where the default wireless network settings don't provide the desired coverage. It's tempting to change the region in the settings to a country with more liberal radiation standards, believing this will instantly solve the weak signal problem. However, the question of "which country to choose" doesn't have a universal answer, as it is directly related to the hardware limitations of your device and the laws of the specific region.
Changing a parameter country The wireless interface configuration does affect the maximum transmit power and available frequency channels. However, blindly copying the "US" or "Israel" settings on a router located in Russia or Europe can lead not only to fines from regulatory authorities but also to network instability due to interference from neighboring access points.
In this article, we will examine in detail the technical aspects of power regulation, the impact of country selection on the operation of protocols 802.11ac And 802.11axWe'll also explain why, in some cases, changing the region won't improve speed at all. You'll understand the difference between a software limitation and the device's physical inability to deliver more power.
How Country Selection Affects WiFi Transmission Strength
The main reason why users search for the "best" country in the settings Mikrotik — is the desire to circumvent restrictions on radiation power. Each state has its own standards determining the maximum effective radiated power (EIRP). These standards are prescribed in legislation and are translated into the operating system's software code. RouterOS.
When you select a specific country from the menu Wireless, the router applies a profile that limits the transmit power on each channel. For example, in some regions of Europe, the power is limited to 20 dBm (100 mW) on certain frequencies, while in the US or Israel this limit may be higher. Changing the country to a region with less stringent regulations allows the router to use higher power values if the hardware allows it.
However, it's important to understand that changing the country's software won't turn a budget model into a professional antenna. If your device's hardware, including signal boosters (PA) and antenna design are designed for a maximum of 23 dBm, then choosing a country with a 30 dBm resolution will have no effect. The router simply won't be able to physically deliver more power than its circuit design allows.
⚠️ Attention: Increasing the transmit power beyond your country's permissible limits may cause the wireless module to overheat and reduce the device's lifespan. Always monitor the processor and radio chip temperature using the menu.
System -> Health.
Additionally, the country you select determines the available channels. In some regions, certain frequencies may be reserved for radar or military use, and the router will be required to support this feature. DFS (Dynamic Frequency Selection), avoiding these channels or switching when interference is detected.
Comparing Regulatory Profiles: The United States, Israel, and Europe
When setting up Mikrotik Three main profiles are most often considered: European (no_country_set or specific EU countries), American (united-states), and Israeli (israel). Each has its own characteristics in frequency distribution and maximum power.
Profile united-states Traditionally considered one of the most powerful, it allows channels up to 160 MHz wide in the 5 GHz band and allows high EIRP values. This is why many users choose this region to maximize coverage. However, using this profile outside the US may violate local radio spectrum laws.
Profile israel is also known for its liberal settings, particularly in the 2.4 GHz band, where high power is permitted on all channels. Meanwhile, European profiles (such as Germany or France) often have stricter restrictions, particularly on channels 36-48 in the 5 GHz band, where power can be artificially reduced by software.
Below is a comparison table of the features of the regulatory profiles available in RouterOS:
| Region / Country | Max. power (approx.) | Available 2.4 GHz channels | 5 GHz Features |
|---|---|---|---|
| united-states | Up to 30 dBm (depending on model) | 1-11 | Wide channels, high limits |
| israel | Up to 30 dBm | 1-13 (high power) | High powers are allowed |
| no_country_set | Limited by standard | 1-13 | IEEE Basic Limits |
| European Union | Up to 20-23 dBm | 1-13 | Strict limits, DFS is mandatory |
It is worth noting that in the latest versions RouterOS v7 company Mikrotik Tightened security policies. Now, when selecting a country other than your current location or attempting to set the power level higher than the hardware's specifications, the system can issue warnings or automatically adjust the settings.
Hardware limitations and the "secret tuning" myth
There's a persistent myth that changing the country is a "secret button" that unlocks the router's hidden potential. In reality, it all comes down to the physical characteristics of the radio module. If your model's specifications hAP ac² or RB951Ui If the output power is stated to be 23 dBm, then no country will make it 30 dBm.
Chip manufacturers (Qualcomm Atheros, MediaTek) set maximum values that are flashed into the device's EEPROM. RouterOS It simply reads this data and applies the selected country's regulatory restrictions on top of it. If the country allows 30 dBm, but the chip only supports 23 dBm, the router will output 23 dBm.
Why might the power be lower than stated?
Actual output power sometimes depends on ambient temperature and supply voltage. If the chip overheats, it can automatically reduce power (thermal throttling) to protect against damage, regardless of country settings.
Moreover, increasing the router's transmit power doesn't mean client devices (smartphones, laptops) will be able to reach it with the same strength. Wi-Fi is a two-way communication. A powerful router will "shout" to a phone from across the apartment, but a weak phone transmitter won't be able to send a response packet back. As a result, you'll see full signal strength, but the internet won't work.
For real signal amplification, it is more effective to use external antennas with a high gain (dBi) or organize a Mesh network, rather than chasing numbers in the country settings.
Legal aspects and user liability
The use of the frequency spectrum is regulated by government agencies (Roskomnadzor in the Russian Federation, the FCC in the US, and the relevant national regulators in the EU). Established standards (SanPiN, GOST) define maximum permissible radiation levels to ensure electromagnetic compatibility and health safety.
By selecting the "united states" country on a router installed in Moscow or Berlin, you're technically violating radio frequency usage regulations. While the likelihood of someone coming to you with a direction finder because of a single router is extremely low, in densely populated areas, your "amplified" signals could interfere with critical infrastructure or your neighbors.
⚠️ Attention: In the event of complaints from neighbors about interference or inspections by regulatory authorities, using an incorrectly set region may result in a fine and confiscation of equipment.
Additionally, some countries (such as Japan or China) have unique frequency ranges whose use is prohibited in other regions. Activating these ranges may cause interference with airport security systems or military installations if you are near them.
Always check your settings against local regulations. If you're unsure of the permissible power, it's safer to leave the default value. no_country_set or choose your real country of residence.
A practical guide to changing the region in Mikrotik
If you have weighed all the risks and decided to change the region for testing coverage, do so in RouterOS It's quite simple. The procedure is the same for the web interface. WinBox and command line.
First, you need to log in to your router. Open WinBox, go to the menu Wireless. Double-click on the name of your wireless interface (usually wlan1 or wifi1 (in new versions). In the window that opens, find the tab Wireless and field Country.
☑️ Check before changing the region
After selecting a new country from the drop-down list, click OK or ApplyThe router will restart the wireless interface, and the changes will take effect. Please note that changing the country may reset some settings, such as channel width or a specific frequency channel, if they are not supported in the new profile.
For those who prefer the terminal, the command looks like this:
/interface wireless set wlan1 country=united-statesAfter executing the command, check the field tx-powerIf the value has increased, then changing the region has worked. If the value remains the same, then you've hit the device's hardware limit.
Alternative ways to improve WiFi coverage
Instead of risky region manipulation, it's often more effective to optimize other network parameters. The first step is choosing the right frequency channel. Use the built-in scanner. Scan on the menu Wirelessto find the least loaded channel.
The second important aspect is channel width. In the 2.4 GHz band, it is often better to use channel width. 20MHz instead of 40MHzThis will reduce the speed, but will significantly increase the stability and penetration of the signal in noisy conditions.
The third method is updating the firmware. New versions RouterOS often contain improvements to wireless signal handling algorithms and driver bug fixes.
⚠️ Attention: Interfaces and menu names may vary depending on the RouterOS version (v6 or v7) and wireless package type (legacy or wifi-qcom). Always check the documentation for your specific software version.
It's also worth checking the physical location of the router. Elevating the device, removing metal obstructions, and properly orienting the antennas (vertically for Omni antennas) often provide a greater boost than software fixes.
Frequently Asked Questions (FAQ)
Does choosing a country affect internet speed?
Indirectly, yes. Choosing a country can open up access to wider channels (for example, 80 or 160 MHz) or less noisy frequencies, which will increase the actual data transfer speed. However, signal strength alone doesn't increase speed; it only expands coverage.
Is it safe to set the country as "united-states" in Russia?
Technically, this is safe for the router (as long as temperature limits are not exceeded). Legally, you're violating Russian Federation radio spectrum regulations. The risks are minimal for home use, but they do exist.
Why didn't the power change after changing the country?
This means your device has a hardware limitation. The wireless chip physically can't deliver more power, regardless of the software region settings. Also, check if the limitation is enabled. max-txpower in the settings.
Do I need to reboot my router after changing country?
Typically, restarting the wireless interface is sufficient, which occurs automatically when applying the settings. However, to ensure that all settings, especially DFS, are applied, a full device reboot is recommended.
