In today's world, where wireless technology has become an integral part of everyday life, many users face the same problem: their router broadcasts two identical networks, and it's unclear which one provides the highest speed. This is often due to the fact that a dual-band router by default creates two SSIDs (network names) for the 2.4 GHz and 5 GHz bands. Understanding 5 GHz Wi-Fi designations is critical for properly connecting devices that require high bandwidth, such as Smart TVs or gaming consoles.
Default naming settings vary by equipment manufacturer and specific model. Typically, certain suffixes or prefixes are added to the base name to indicate the frequency range. If you see networks ending in _5G, _5GHz or _AC, know that this is exactly the high-speed range you need for stable 4K work and online gaming.
In this article, we'll take a detailed look at all the possible designations, review the settings for popular router brands, and explain why it's important to distinguish between these frequencies. You'll learn not only how to find the right network but also how to correctly configure the network name (SSID) in your router's interface to avoid future confusion.
Basic principles of naming wireless networks
The name of the wireless network, technically known as SSID (Service Set Identifier), created by the equipment manufacturer at the factory. By default, most routers use a combination of the brand and a random set of characters, for example, TP-Link_2A4BHowever, when it comes to dual-band devices that support 802.11ac (Wi-Fi 5) and 802.11ax (Wi-Fi 6), the system must somehow differentiate between the bands for the user.
The most common method is to add a postfix to the main name. If your router is called HomeWiFi, the 2.4 GHz network may remain unchanged, but a suffix will be automatically added for the 5 GHz frequency. This is done so that the user can visually identify the faster channel. It is critical to understand that physically this is one router, but the radio modules operate on different frequencies, hence the separation of names for manual selection.
Some manufacturers are implementing the function Smart Connect or Band SteeringIn this case, the router combines both bands under a single SSID. The device automatically decides which frequency to connect to based on signal strength and standard support. However, for manual troubleshooting or forced connection of older devices, separate SSIDs are often required.
⚠️ Attention: If you rename a network in your router settings, make sure you use Latin characters. Cyrillic characters or special characters may prevent some devices (especially printers and smart plugs) from seeing the 5 GHz network.
Standard designations for different router manufacturers
While there's no single global standard for suffixes, major vendors adhere to certain rules to make life easier for users. Knowing these patterns will help you instantly determine what signal your smartphone or laptop is receiving. Let's take a look at the most popular brands.
Devices from TP-Link And Tenda most often use the addition _5G or simply _5G at the end of the name. For example, if the base name MyHome, then the high-speed network will be MyHome_5GProducts from ASUS often marked with a suffix _5G or _5GHzIn some firmware versions Keenetic you can find the addition _5G by default, unless the "Unified Network" feature is enabled.
Routers from providers such as Sagemcom or Sercomm, often have more complex designations that include the device model. For example, RT_5G_2A. It is also important to pay attention to Wi-Fi standards: sometimes a _AC or _AX, which also indicates support for high-speed 5 GHz bands.

How to distinguish frequencies in Windows and Android settings
Operating systems display information about a connected network differently. In Windows 10 and 11, if you click the Wi-Fi icon in the system tray, you'll see a list of available networks. However, to find out exactly what frequency you're using, you need to go to the connection properties. Click Properties active network and scroll down to the "Properties" line. It will say: Range: 5 GHz.
On devices with Android The situation is similar, but depends on the OS version and the manufacturer's shell (Samsung One UI, Xiaomi MIUI, stock Android). In most cases, simply tap the name of the connected network in the Wi-Fi settings. The menu that opens will contain a line labeled "Frequency" or "Band," indicating 5 GHz or 2.4 GHzOn some smartphones, the frequency is displayed directly in the list of available networks in small print under the name.
Users iOS (iPhone, iPad) are at a disadvantage. Apple hides technical information about the frequency in the standard interface. To find out how 5 GHz Wi-Fi is designated on an iPhone and which network you're connected to, you'll have to use third-party utilities, such as AirPort Utility (requires debug mode to be enabled in phone settings) or Wi-Fi analysis apps that show channel and bandwidth.
⚠️ Attention: Operating system interfaces and router firmware are subject to update. The location of the "Properties" or "Frequency" menu items may change in new versions of iOS, Android, or Windows. If you don't find the information immediately, use the settings search.
Range characteristics comparison table
Understanding the differences between frequencies helps not only choose the right network but also optimize your home internet. Below is a comparison of key parameters that influence network selection.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Transfer speed | Up to 150-450 Mbps | Up to 1300 Mbps and higher |
| Range of action | High (better through walls) | Average (poor at overcoming obstacles) |
| Workload | High (a lot of interference from neighbors) | Low (many free channels) |
| Device support | All devices (including old ones) | Only modern gadgets (Wi-Fi 5/6) |
The table shows that for devices located far from the router or behind several walls, the 2.4 GHz network may be more stable, despite the slower speed. However, for streaming video and gaming, 5 GHz should always be prioritized.
Why is 5 GHz worse at passing through walls?
Wave physics dictates that the higher the signal frequency, the shorter its wavelength. Short waves (5 GHz) are more easily absorbed and reflected by dense materials such as concrete, metal, and water (found in walls and plants) than long waves (2.4 GHz).
Setting up network naming in the router's web interface
If you're not happy with the default designation, you can always change the network name (SSID) manually. To do this, you need to log into the router's web interface. This is usually done by entering the address 192.168.0.1 or 192.168.1.1 in the browser. The login and password are often located on a sticker on the bottom of the device.
After logging in, find the section related to wireless network. It may be called Wireless, Wi-Fi, Wireless mode or WLANInside, you'll see settings for both ranges. They're often located in different tabs or have a range selector switch.
☑️ Network renaming algorithm
In the field SSID Name or Network name Enter the desired name. It is recommended to add a descriptive suffix, for example, _5G_FAST or _Gaming, so you can immediately see where you're connecting. Don't forget to click the button Save or ApplyAfter this, the router will restart the wireless module, and you will need to reconnect all devices using the new password (if you changed it) or simply selecting a new network.
Problems with 5 GHz network visibility
It happens that you are looking for a network with an ending _5G, but it's simply not listed. The first and most common reason is that your device doesn't support this band. Older laptops (manufactured before 2013-2014) and budget smartphones often only have 2.4 GHz Wi-Fi modules. In this case, you won't physically see a 5 GHz network, no matter how hard you search.
The second reason is region. Wi-Fi standards are regulated by law in different countries. Some channels in the 5 GHz band may be banned in your country, and a router configured for a different region may hide the network or cause instability. Check the region settings in the router interface (usually in the Advanced -> Wireless -> Advanced Settings).
The third reason is the operating mode. If the router's 5 GHz settings are set to support only older standards (e.g., 802.11a/n only), and your device is searching for ac/ax, the network may not display correctly. It is recommended to select mixed mode. 802.11 a/n/ac/ax mixed.

⚠️ Attention: Changing the region in your router settings may be illegal in your country, as it affects radio spectrum usage. Use this feature only if you are sure it complies with regulations or if you are traveling.
Frequently Asked Questions (FAQ)
Is it possible to combine 2.4GHz and 5GHz network names into one?
Yes, this feature is called Smart Connect, Band Steering, or simply "Combine 2.4 GHz and 5 GHz Networks." It's available in the settings of most modern routers. When enabled, the router will automatically direct the device to the most suitable frequency. However, if you have specific needs (for example, a smart home that only works on 2.4 GHz), it's better to keep the networks separate.
Why does the 5GHz speed drop when I move to another room?
The 5 GHz signal has a shorter wavelength, so it bends less around obstacles and fades faster in space than 2.4 GHz. A single solid wall can reduce the speed by half. To solve this problem, use a mesh system or a repeater that supports 5 GHz.
How do I know if my laptop supports 5GHz?
In Windows, click Win + R, enter cmd and press Enter. In the black window, enter the command netsh wlan show driversFind the line "Supported radio module types." If it mentions 802.11a, 802.11ac, or 802.11ax, it's supported.
Does the network name affect internet speed?
No, the name (SSID) itself is simply an identification label. It has no effect on the technical data transfer rate. Speed depends on the Wi-Fi standard (n, ac, ax), channel width, and signal strength.
