Modern MGTS tariff plans, especially those based on GPON technology, offer speeds of 500 Mbps, 1 Gbps, and even higher. However, many subscribers experience a situation where the actual wireless speed is significantly lower than stated in the contract, and the cause lies in the frequency range.
The thing is that the standard range 2.4 GHz, which is the default on most devices, has limited bandwidth and is heavily polluted by neighboring routers, microwaves, and Bluetooth devices. Therefore, to unlock the full potential of fiber optic internet, it is necessary to activate and configure 5 GHz.
In this article, we'll take a detailed look at how to make MGTS 5 GHz WiFi available to all your devices, explore the nuances of setting up equipment from various vendors (Huawei, ZTE, Keenetic), and help you troubleshoot common high-frequency connection issues.
Benefits of moving to 5 GHz
The transition to high-frequency bands isn't just a marketing ploy, but a technical necessity for high-speed internet users. Unlike the "old" band, which is often compared to a narrow road clogged with traffic jams, the frequency 5 GHz provides a wide free corridor for data transmission.
The main advantage is that absence of channel intersectionsThe 2.4 GHz band has only three non-overlapping channels, which can cause speed drops in apartment buildings even with a strong signal. The 5 GHz band has up to 23 non-overlapping channels, allowing your router to operate in "clear air."
⚠️ Please note: The 5 GHz signal range is shorter than that of 2.4 GHz because high-frequency waves are less able to bypass obstacles. This is normal and does not indicate a hardware malfunction.
In addition, the standard 802.11ac (WiFi 5) and new 802.11ax (WiFi 6) operate primarily or exclusively in this band, ensuring maximum data transfer speeds. If your smartphone or laptop supports these standards, you'll be able to download large files and watch 4K video without buffering.
Checking the compatibility of MGTS equipment
Before you begin setting up your equipment, you need to ensure that it's technically capable of operating in high-frequency mode. MGTS offers subscribers a variety of router models, from older single-band devices to modern dual-band systems.
Most often, the provider provides devices from companies Huawei (series HG8245, HG8145), ZTE (F660, F670) or EltexThere is usually a marking on the router body. Dual Band or logo AC, which indicates support for two bands. If the router is old and only supports 802.11n, it is not possible to enable 5 GHz programmatically - the hardware will need to be replaced.
It's also important to check the receiver (client device). Laptops manufactured before 2013-2014 and budget smartphones may not have a 5 GHz module. In the Windows Device Manager, under "Network Adapters," the model should be listed. 802.11ac or Dual Band.
For a more accurate diagnosis, you can use specialized utilities that will display available networks and their characteristics. This will help you determine whether your adapter can see your neighbors' high-bandwidth networks.
- 📱 WiFi Analyzer (Android): shows a graph of channel load and the presence of 5 GHz networks.
- 💻 AirPort Utility (iOS): Apple's built-in signal quality assessment app.
- 🖥️ InSSIDer (Windows/Mac): professional tool for analyzing the broadcast environment.
Login to the router's web interface
To make changes to your wireless network configuration, you need to access the router's control panel. This can be done through any browser, connected to the device via cable or WiFi. The login address is often located on a sticker on the bottom of the device.
Standard addresses for MGTS equipment are usually as follows: 192.168.1.1, 192.168.100.1 or domain name 192.168.0.1In the login and password field you are most often required to enter admin / admin or admin / password, if you haven't changed them before.
Important: When logging in via WiFi, the connection may be interrupted when changing frequency settings. Therefore It is better to configure the channel and bandwidth from a device connected via a LAN cableto avoid losing access to the admin panel.
If the default data doesn't work, your provider may have changed it remotely. In this case, you should contact MGTS technical support or try resetting your router to factory settings (press the Reset button), keeping in mind that this will delete your customized PPPoE/VLAN settings if they aren't saved automatically.
Setting up 5 GHz on Huawei and ZTE routers
The interfaces of the equipment provided by MGTS may differ, but the setup logic remains similar. Let's look at the algorithm for popular models.
For routers Huawei (for example, HG8245Q, HG8145V5) after logging in, you need to go to the tab WLANHere you'll see a division between 2.4G Basic Network Settings and 5G Basic Network Settings. We're interested in the latter.
In the section 5G Basic Network Settings you need to tick the box Enable WLAN. Next, you should select the operating mode (Mode). The optimal choice would be 802.11ac or 802.11an/ac mixedto ensure compatibility with all modern devices.
Huawei/ZTE Setup Checklist
On devices ZTE (F660, F670) the path may look like Network -> WLAN -> 5G. Here you also need to activate the radio interface. Pay attention to the parameter Channel Width (Channel width). For maximum speed, select 80 MHz, but if the signal is unstable, you can reduce it to 40 MHz or 20 MHz.
Don't forget to set a unique network name (SSID) for the 5 GHz band, for example, by adding the suffix "_5G" to the main name. This will help you visually distinguish networks when connecting devices.
Configuration of dual-band Keenetic routers
If you are using a router Keenetic (which is also often found among MGTS subscribers or purchased separately), the setup here is most convenient and flexible. The Keenetic OS interface allows for fine-grained control of the radio modules.
Go to the menu My Networks and Wi-Fi -> Home networkYou'll see settings for the 2.4 GHz and 5 GHz bands. Make sure the 5 GHz switch is enabled. Keenetic can group networks under a single name by default (Band Steering), but for diagnostic purposes, it's best to separate them.
In the section Additional settings For 5 GHz, you can select a specific channel. The recommended mode is Auto, but if you experience interruptions, select one of the free channels (36, 40, 44, 48). The transmitter power is also adjusted here.
A unique feature of Keenetic is the ability to create a guest network or a separate network for IoT devices in the 5 GHz band, which increases the overall security and stability of the home network.
What is Band Steering?
Band Steering is a technology that allows the router to automatically direct the client device to the most appropriate frequency (2.4 or 5 GHz) depending on signal quality and load. The router automatically "switches" the phone to 5 GHz when you get close, and to 2.4 GHz when you move away.
Selecting a channel and bandwidth
Choosing the right channel is key to stable WiFi performance. In the 5 GHz band, channels don't overlap as much as in 2.4 GHz, but interference from radar (DFS) or powerful neighboring routers is still possible.
Channel width determines the "thickness" of the pipe through which data travels. Standard values are 20, 40, 80, and 160 MHz. The wider the channel, the higher the speed, but the shorter the range and the greater the sensitivity to interference. For most apartments, the optimal width is 80 MHz.
DFS (Dynamic Frequency Selection) is a mechanism that forces the router to avoid channels used by radar services. If the router detects radar, it may temporarily switch channels, causing a brief connection interruption. If you are near an airport or military installation, you may want to manually select channels outside the DFS range (for example, 36-48 or 149-165, if these are permitted in Russia).
| Parameter | Recommended value | Impact on the network |
|---|---|---|
| Mode | 802.11ac / ax | Maximum speed and support for new devices |
| Channel width | 80 MHz | Balance between speed and stability |
| Channel | Auto / 36, 40, 44 | Avoiding intersections with neighbors |
| Power | 100% (or High) | Increasing the coverage radius |
Use WiFi analyzers on your smartphone to find the least congested channel and manually select it in your router settings, disabling automatic selection if the network is unstable.
Typical problems and solutions
Even after enabling 5 GHz, users may encounter a number of issues. The most common problem is that the device doesn't detect the new network. This almost always indicates that the device's network adapter is incompatible with the 5 GHz band.
The second common scenario is low speed or constant disconnections. This can be caused by the router being in a metal enclosure, behind a TV, or in a distant room. High frequencies don't penetrate concrete walls with rebar very well.
⚠️ Please note: MGTS router interfaces may be updated by the provider. Button locations and tab names may differ slightly from those described in the instructions.
It's also worth checking the WiFi adapter drivers on your computer. Visit the laptop or motherboard manufacturer's website and download the latest driver. Older drivers may not work correctly with new encryption standards or channel bandwidth.
If your router overheats and reboots under load, it may be lacking ventilation. Overheating of the WiFi processor often leads to a drop in speed or the disappearance of the 5 GHz network.
Frequently Asked Questions (FAQ)
Why doesn't my phone see the 5 GHz network, even though my router is dual-band?
Most likely, your smartphone or tablet is a budget model or was released several years ago and does not physically have a module for receiving the 5 GHz frequency. Check the device's specifications on the manufacturer's official website.
Do I need to change my MGTS router to get 5 GHz working?
You only need to upgrade your router if your current model is single-band (2.4 GHz only). If the router says "Dual Band" or "AC" on the case, simply enable the feature in the settings.
What is the actual speed at 5 GHz through a wall?
Through a single brick or concrete wall, speed can drop by 30-50%. Through two or more solid walls, the 5 GHz signal can be completely lost. In such cases, a mesh system or repeater is recommended.
Can 5 GHz be harmful to health?
No, WiFi router radiation is classified as non-ionizing radiation and is within safe limits established by international standards. The power of a household router is hundreds of times lower than the maximum permissible limits.
