How to switch your Wi-Fi network to 5 GHz: Complete instructions for all router brands

Have you noticed that your Wi-Fi is slow, despite your high-speed plan? Or do you want to reduce interference from neighboring networks? Switching frequencies 5 GHz This band may be the solution—it offers greater throughput, less congestion, and a more stable connection for modern devices. However, not everyone knows how to properly configure a router to work in this band, especially if they previously only used a standard one. 2.4 GHz.

In this article, we'll cover not only the basic steps for changing frequencies, but also the nuances that are often overlooked: from checking the compatibility of your devices to optimal channel settings for maximum speed. You'll learn why sometimes 5 GHz works worse, than expected, and how to fix it without calling a technician. And if your router doesn't support dual-band mode, we'll tell you what to do.

What's the difference between 2.4 GHz and 5 GHz: which is better to choose?

Before switching, it's important to understand the key differences between the bands. Frequency 2.4 GHz — is a "veteran" of wireless networks: it penetrates walls better, has a large coverage area, but suffers from congestion (especially in apartment buildings). While 5 GHz offers:

  • 🚀 High speed — up to 1300 Mbps versus a maximum of 600 Mbps at 2.4 GHz (when using the standard 802.11ac).
  • 📶 Less interference — fewer devices operate in this range (microwaves and Bluetooth headsets do not interfere).
  • 🔄 More channels — 23 non-overlapping channels versus only 3 in 2.4 GHz.

However, 5 GHz There are also some downsides: shorter range (the signal passes worse through obstacles) and incompatibility with older devices (For example, some smartphone models from 2015-2017 or budget smart light bulbs). If you need coverage over a large area (like a country house), it might be worth leaving both bands on.

Checking device compatibility with 5 GHz

Before setting up your router, make sure your devices support it. 5 GHzHere's how to check:

  • 📱 Smartphones/tabletsGo to your Wi-Fi settings and look at the list of available networks. If there are any networks marked 5G or 5GHz — your device is compatible. Android You can also install the application WiFi Analyzer for detailed information.
  • 💻 Laptops/PCs: IN Windows open Device Manager → Network Adapters. If the adapter name contains Dual Band, 802.11ac or 802.11ax — there is support. On Mac check in About This Mac → System Report → Network → Wi-Fi.
  • 🖥️ TVs/set-top boxes: There should be an option to select a band in the Wi-Fi settings menu. For example, on Samsung Smart TV 2018+ and Apple TV 4K 5 GHz support is by default.

Attention! Some budget devices (eg. Xiaomi Mi Band, cheap IP cameras or printers) only work on 2.4 GHzIf you use such gadgets, you will either have to leave both ranges or buy adapters (for example, TP-Link TL-WA850RE to expand the 2.4 GHz network).

List of popular devices with 2.4 GHz ONLY

  • Smart light bulbs Yeelight (models before 2020)
  • Fitness bracelets Honor Band 4/5
  • Prefixes Amazon Fire TV Stick Lite
  • Most budget IP cameras (TP-Link Tapo C100 and similar)

Step-by-step instructions: how to enable 5 GHz on a router

The setup process varies depending on the router model, but the general process is the same. We'll cover a universal algorithm with examples for popular brands.

  1. Log in to the router's web interface:
    • Connect to the router's network via cable or Wi-Fi.
    • Open your browser and enter in the address bar 192.168.0.1 or 192.168.1.1 (the exact address is indicated on the router sticker).
    • Enter login/password (usually admin/admin or admin/password from sticker).
  2. Find the wireless network section:
    • On TP-Link: Wireless → Wireless Settings.
    • On ASUS: Wireless Network → General.
    • On Keenetic: Wi-Fi → Hotspot.
  • Activate 5 GHz:
    • Select mode 802.11a/n/ac or 802.11ax (Wi-Fi 6).
    • Specify a separate network name (SSID) for 5 GHz, for example, MyWiFi_5G.
    • Select the channel manually (recommended) 36, 40, 44 or 48 - they are less busy).
    • Save the settings and reboot the router.

    Is there a separate SSID for 5 GHz?|Is the channel selected manually (not Auto)?|Is the channel width no more than 80 MHz (for stability)?|Is WPA3 or WPA2-PSK enabled (not WEP!)?

    -->

    Attention! If there is no option to select a range in the settings, your router does not support 5 GHzIn this case, you will either have to update the firmware (if the manufacturer has added support in new versions) or buy a new router with support. Dual Band.

    Optimal settings for maximum speed on 5 GHz

    Easy to turn on 5 GHz It's not enough - you need to configure the parameters correctly to avoid connection drops and use the full potential of the range.

    Parameter Recommended value Explanation
    Network mode 802.11a/n/ac or 802.11ax Ensures compatibility with all modern devices.
    Channel width 40 MHz or 80 MHz 160 MHz gives maximum speed, but can be unstable in urban conditions.
    Channel 36, 40, 44, 48 (DFS) Channels 52-144 can be automatically switched off when radars are detected (at airports).
    Transmission power 100% or High Reduce only if the router is overheating.

    Critical error: If you select a channel in the DFS range (52-144), the router may periodically "drop" for 1-5 minutes when detecting radar. This is normal behavior, but it is inconvenient for online gaming or video calls. For stability, it is better to use channels 36-48, even if they are a little busier.

    Common problems and solutions when switching to 5 GHz

    Even after proper setup, users still encounter common issues. Here are the most common ones and how to resolve them:

    • 🔌 The device does not see the 5 GHz network:
      • Check if the range is enabled in your router settings (sometimes it is disabled by default).
      • Update the Wi-Fi adapter driver on your device (especially relevant for laptops running Windows).
      • Make sure that your router does not have a MAC address restriction.
    • 📉 Speed ​​is lower than 2.4 GHz:
      • Try reducing the channel width with 80 MHz to 40 MHz - this will reduce the speed, but increase stability.
      • Check if there is a microwave or other device nearby that is causing interference.
      • Disable the feature Mu-MIMO or Beamforming in the router settings - sometimes they don't work correctly.
    • 🔄 Constant connection breaks:
      • Change the channel to a fixed one (not Auto).
      • Turn off Wi-Fi power saving in the Power Settings (Windows).
      • If your router is overheating, place it in a ventilated area or use a cooling pad.

    Attention! If after switching to 5 GHz The Internet has disappeared on all devices. Check if the settings have been reset. WAN (Sometimes resetting the configuration also affects the connection to the provider.) In this case, simply re-enter the provider data in the section Internet or WAN.

    How to improve 5 GHz coverage in a large home

    The main drawback 5 GHz - shorter range compared to 2.4 GHzIf the signal is weak or drops out in some rooms, try these tips:

    • 📡 Use Mesh systems: For example, TP-Link Deco or ASUS ZenWiFi automatically switch devices between ranges and access points.
    • 🔄 Set up roaming: If you have multiple routers, give the 5GHz networks the same name (SSID) and a password - devices will automatically connect to the nearest point.
    • 📶 Install a 5 GHz-capable repeater: For example, Netgear EX6150 or Tenda A18It is important that the repeater supports Dual Band.
    • 📍 Optimize your router's location:
      • Place it in the center of the house, not in a corner.
      • Avoid placing near metal objects or mirrors.
      • Raise the router to a height of 1-2 meters (for example, on a shelf).

    If you use Mesh system, pay attention to the setting Band Steering (automatic switching between ranges). This function is available in most modern systems (for example, Google Nest WiFi or Ubiquiti AmpliFi). However, sometimes it's better to disable it if devices are stuck on a less-than-optimal range.

    When should you not switch to 5 GHz?

    Despite all the advantages, 5 GHz It's not for everyone. Here are some situations when it's better to stay on 2.4 GHz or use both ranges:

    • 🏡 Large home/office area (more than 100 m²) without the possibility of installing additional access points.
    • 📱 Old devices (released before 2016) that do not support 5 GHz.
    • 🔌 Smart home with affordable devices (most sensors and relays only work at 2.4 GHz).
    • 🚗 Connection in the garage or outside — 5 GHz signal does not penetrate concrete walls well.

    Also keep in mind that some providers (especially in rural areas) may limit speed on 5 GHz Due to hardware issues. Please check with technical support if the speed hasn't improved after switching.

    📊 Have you tried switching to 5 GHz yet?
    Yes, everything works fine.
    Yes, but the speed hasn't increased.
    No, I haven't tried it.
    My router does not support

    FAQ: Answers to frequently asked questions

    Can I use the same network name (SSID) for 2.4GHz and 5GHz?

    Yes, but it's not always convenient. Many routers allow you to combine networks under a single name (function Smart Connect at ASUS or Band Steering at Netgear). However, in this case, the devices themselves select the range, which can lead to a connection to a less optimal network. For example, a smartphone may become stuck on 2.4 GHz, even if 5 GHz accessible and free.

    We recommend using different names (for example, MyWiFi And MyWiFi_5G) to manually select the desired range.

    Why is the 5GHz speed slower than expected?

    There are several reasons:

    1. Your device only supports 802.11n (maximum 450 Mbps), not 802.11ac (up to 1300 Mbps).
    2. The channel width is set to 20 MHz instead of 40/80 MHz.
    3. It's enabled in the router settings. QOS or Traffic Control, which limits the speed.
    4. The provider provides a tariff with a speed limit (for example, 100 Mbps), and even at 5 GHz you will not get more.

    Check the speed via cable - if it is the same, the problem is not with Wi-Fi.

    How do I know what frequency my device is connected to?

    The methods depend on the operating system:

    • Windows: Open Settings → Network and Internet → Wi-Fi, click on the network name → view properties. The protocol will be listed there (for example, 802.11ac means 5 GHz).
    • Android: Install the application WiFi Analyzer - it will show the frequency of the current connection.
    • MacOS: Hold down Option and click on the Wi-Fi icon in the menu bar - information about the standard will appear (for example, 802.11a = 5 GHz).
    • iOSThere are no native tools, but you can use an app Network Analyzer.
    Should I disable 2.4GHz after switching to 5GHz?

    Not necessarily. The best option is to leave both ranges, but with different names (SSID). This will allow:

    • Connect older devices that do not support 5 GHz.
    • Use 2.4 GHz for tasks that don't require high speed (such as smart home).
    • Automatically switch to 2.4 GHz if the 5 GHz signal weakens (for example, in the far corner of the apartment).

    If all your devices support 5 GHz and you are satisfied with the coverage area, you can turn it off 2.4 GHz to reduce interference.

    My router doesn't support 5 GHz. What should I do?

    There are several solutions:

    1. Buy a new router with support Dual Band or Tri-Band (For example, TP-Link Archer AX6000 or ASUS RT-AX88U).
    2. Use a 3G/4G router with 5 GHz (For example, Huawei B535) as the main one.
    3. Connect an external Wi-Fi adapter to the router via USB (if the model supports this function, for example, Keenetic with adapter TL-WN822N).
    4. Set up a 5 GHz guest network from your neighbor (if he doesn't mind) and connect to it for high-speed tasks.

    If buying a new router isn't an option, try renting equipment from your provider—many offer modern models for a small fee.
