When initially setting up a wireless interface in RouterOS, administrators often encounter a question that many people either guess at or leave at the default setting. country code (country code) in the Wireless section affects available frequencies, maximum transmitter power, and the list of permitted channels. An incorrect selection may result in your equipment operating illegally or not being able to communicate with client devices.
Many users mistakenly believe that this parameter is only necessary for legal compliance, but the technical side of the issue plays no less a role. Different regions use different radio frequency spectrum standards, and ignoring this fact causes problems with roaming and connection speed. In this article, we'll take a detailed look at how to choose the optimal locale for your equipment. MikroTik and why automatic mode is not always the best solution.
It's worth noting that radio module settings directly impact the physical availability of the network in your location. If you select a region with strict power restrictions, the coverage range may be insufficient for a large office or home. On the other hand, choosing a region that's too "liberated" may interfere with neighboring equipment and violate the laws of your country.
Legal aspects and standards of radio regulation
Each country has its own regulatory body that determines the rules for the use of the radio spectrum. In the United States, it is FCC, in Europe - ETSI, and in Russia, the State Commission on Radio Frequencies. These organizations set limits on the maximum radiation power and determine which channels can be used in the 2.4 GHz and 5 GHz bands. When you select a specific country in the settings Wireless, you are actually downloading a restrictions profile that complies with the laws of that state.
Using a different country profile, such as installing United States While operating equipment in Germany or Russia is technically a violation, in practice this is rarely monitored in private homes, in the corporate sector, or when used outdoors, it can result in fines. Furthermore, equipment operating at power levels above the permitted level can create critical interference to other services, including aviation or military frequencies in some regions.
⚠️ Warning: Using a country profile different from your actual location may result in legal liability and disruption to critical infrastructure. Always check local laws before changing your regulatory domains.
Technically, RouterOS blocks the ability to select channels and power levels that are prohibited by the selected profile. If you attempt to manually set a power level higher than the permitted level for the selected location, the system will either ignore the command or automatically reduce the value to the maximum permitted level. This is a firmware-integrated protection mechanism that cannot be bypassed without violating the license or using modified versions of the software.
Impact of Country Code on Available Channels and Power
The main reason administrators change the default settings is channel availability. In the 2.4 GHz band, the situation is relatively simple: in most countries, 13 channels are available, but in some countries, such as the US, only the first 11 are allowed. If you live in a densely populated area and select a profile united-states, you will lose the ability to use channels 12 and 13, which may be free of interference.
The situation with the 5 GHz band is much more complex and dramatic. It contains so-called DFS (Dynamic Frequency Selection) channels, which are used by radar (meteorological) and military applications. Depending on the selected region, the number of available non-DFS channels may vary. For example, the profile russia or europe Provides access to a wide spectrum of frequencies, while other regions may have significant limitations. This is critical for deploying high-density networks, where access points need to be distributed across non-overlapping frequencies.
Transmitter power (Tx Power) is also strictly tied to the selected code. Some regions allow transmission of up to 30 dBm (1000 mW) in certain bands, while others limit it to 20 dBm (100 mW). It is important to understandIncreasing power doesn't always solve the coverage issue, as client devices (smartphones, laptops) have limited response power. However, for directional antennas (CPE), choosing the right region allows you to get the most out of the hardware.
When switching country profiles, the wireless network interface often restarts, causing a brief connection loss. This is normal behavior, as the radio module needs to adapt to the new frequency ranges. It is recommended to make these changes during a maintenance window or off-peak hours.
Client device compatibility issues
One of the most common issues users encounter after changing regions is the disappearance of network connectivity on mobile devices. This occurs because client devices also have their own regional settings and can ignore channels considered illegal in their current location. For example, if an access point MikroTik operates on channel 13 (permitted in Russia and the EU), but an iPhone with US settings will not see this network at all.
The issue of the 5 GHz band and channel width support is particularly pressing. Some older or low-end devices may not support 80 MHz or 160 MHz channel widths in certain frequency bands if they are not permitted in their region. This results in the device either not connecting or dropping to 802.11a/n speeds, ignoring ac/ax standards. Selecting the correct country helps avoid situations where a "smart" router and a "dumb" client cannot agree on connection parameters.
⚠️ Important: If your client devices no longer see the network after changing countries, check that you're not using channels prohibited in the region where these devices were manufactured. Resetting to default settings or selecting the "no_country_set" profile (with caution) often helps.
Also worth mentioning is the problem roamingFor fast and seamless client transfer between access points, it is desirable that all access points in the network broadcast the same set of parameters and be in the same regulatory domain. If one access point is configured to latvia, and the other one on germany, this may cause conflicts when the client tries to switch, since the lists of available frequencies and power limits will differ.
Why do some devices ignore channels 12 and 13?
Many devices (especially those from the US and Japan) scan only channels 1-11 in the 2.4 GHz band by default. This is due to FCC certification. If your access point operates on channel 12 or 13, these devices are simply "unaware" of the network's existence on that frequency and won't attempt to connect.
Comparison of popular country profiles
The choice of a specific profile depends on your needs and location. Below is a comparison of the most commonly used settings in RouterOS to help you make an informed decision. There is no "best" country for all situations, but there are optimal solutions for specific scenarios.
| Country profile | 2.4 GHz Band (Channels) | 5GHz Band (Features) | Max. power (approx.) |
|---|---|---|---|
| no_country_set | All (1-14) | All channels, high limits | Maximum (up to 30 dBm) |
| russia / europe | 1-13 | Wide spectrum, DFS allowed | Standard (20-23 dBm) |
| united-states | 1-11 | Limited spectrum, strict DFS | High, but fewer channels |
| japan | 1-14 (partially) | Specific frequencies | Low/Medium |
Profile no_country_set Often chosen by enthusiasts who need to unlock all possible channels and maximize power, this mode disables DFS mechanisms and other protections, which can lead to interference with radar and unstable operation in noisy environments. It's the choice for isolated laboratory networks or point-to-point networks in remote areas.
For home use in Europe and Russia, the optimal choice remains the profile europe or russia (if available separately). They provide a balance between the number of available channels and regulatory compliance. In office scenarios where multiple access points need to be deployed, it's important to properly distribute channels within the permitted profile to avoid interference.
Instructions for changing the region on MikroTik
Changing your Wi-Fi country is fairly simple, but requires careful attention. Changes take effect immediately, so make sure you're connected to the Wi-Fi network or use a wired connection while setting up the settings.
To configure the settings via the WinBox graphical interface, follow these steps:
- 📡 Open the menu
Wirelessin the left control panel. - ⚙️ Double-click on the name of your wireless interface (usually wlan1 or wifi1).
- 🌍 In the window that opens, find the field Country and select the desired region from the drop-down list.
- ✅ Click
Applyand thenOKto save changes.
If you prefer the command line (Terminal), use the following command. It allows you to quickly change a parameter without having to navigate through menus.
/interface wireless set [find] country=latviaIn this team latvia can be replaced with any other country code supported by your version of RouterOS. After executing the command, the interface may briefly go into a state disabled and turn it on again. If you are using the package wifiwave2 or new drivers wifi-qcom In RouterOS v7, the path to the settings may be slightly different, but the logic remains the same: look for the parameters country in the radio interface configuration.

Features of working in RouterOS v7 and new standards
With the release of the seventh version of the MikroTik operating system and the introduction of the standard Wi-Fi 6 (802.11ax), the approach to spectrum management has become more flexible, but also more complex. New driver packages, such as wifiwave2 And wifi-qcom-ac, have their own tables of regulatory domains. In some cases, old country codes may be replaced with new formats or require the installation of additional packages.
New software versions now offer more granular DFS tuning. The system can now dynamically switch channels upon detection of radars, provided the appropriate country profile is selected. This improves network stability in urban areas where the airwaves are oversaturated with signals. However, it's important to remember that DFS algorithms require scanning time (usually up to 60 seconds at startup) before the network becomes available to clients.
⚠️ Note: Interfaces and available options in RouterOS may change with updates. If you don't see the Country parameter in the usual location, check the documentation for your specific software version or the WiFi driver package you're using.
Channel width management has also been improved in the new versions. While in v6, wide channel selection (80/160 MHz) could be blocked by the country profile, in v7 the system more intelligently selects primary and secondary channels, trying to avoid occupied spectrum areas even within the same regulatory domain.
What happens if you choose the wrong country?
In the worst case, you could break the law and interfere with intelligence agencies. In the best case, you'll experience unstable WiFi, clients will drop, and speeds will be low due to interference or the use of prohibited channels that devices simply ignore.
Is it possible to increase WiFi strength by changing countries?
Technically, choosing a profile with less stringent restrictions (for example, no_country_set) can remove software power limits. However, this doesn't guarantee a better signal, as the physical limits of the antenna and chip remain the same, and the risk of interference increases.
Why did 5 GHz disappear after changing countries?
The selected country profile may not support 5 GHz operation or may limit the specific channels your network operates on. Check your channel and bandwidth settings after changing your region.
How do I find my MikroTik country code?
Codes are usually written in English in lowercase letters (for example, us, de, ru). The full list of supported codes can be found in the drop-down list in the interface or in the MikroTik documentation for your version of RouterOS.
