The speed and stability of a Wi-Fi network directly depend on the selected frequency - 2.4 GHz or 5 GHz. Routers TP-Link While these settings allow for flexible configuration, not all users know how to properly switch between bands. In this article, we'll discuss why this is necessary, how to check the current frequency, and how to change it via the web interface or mobile app.
Frequency 2.4 GHz Provides better coverage over a large area, but suffers from interference (especially in apartment buildings). Range 5 GHz Faster and more stable, but less able to penetrate walls. The choice depends on your needs: 5 GHz is suitable for online gaming and 4K video, while 2.4 GHz is better for smart home devices and older devices.
Important: not all models TP-Link support both ranges. For example, budget routers of the series TL-WR840N work only at 2.4 GHz, and flagships like Archer AX6000 — on both. Check the specifications of your model before setting up.
Why change the Wi-Fi frequency on a TP-Link router?
Switching between 2.4 GHz And 5 GHz solves specific problems:
- 📶 Weak signal — If devices lose connection in remote rooms, switch to 2.4 GHz (it passes through obstacles better).
- 🎮 Lags in games — for online shooters and streaming, choose 5 GHz (less interference, lower ping).
- 📱 Old devices — gadgets before 2015 often do not support 5 GHz (for example, some models Samsung Galaxy S3 or iPhone 4).
- 🏠 There are many networks around — in urban conditions, 2.4 GHz is overloaded, and 5 GHz is freer.
Another reason is - load sharingIf you have a dual-band router (for example, TP-Link Archer C6), you can separate your devices: your TV and laptop can be on the 5 GHz band, while smart bulbs and cameras can be on the 2.4 GHz band. This will reduce mutual interference.
⚠️ Please note: Some devices (eg. Amazon Echo Dot 2nd generation or Xiaomi Mi Band 3) only operate at 2.4 GHz. Check the compatibility of your devices before changing frequencies.
How to find the current Wi-Fi frequency on TP-Link
Before changing settings, check which frequency is currently being used. There are three ways:
- Via the router's web interface:
- Open your browser and type
192.168.0.1or192.168.1.1(the address is indicated on the router sticker). - Enter login/password (default)
admin/admin). - Go to
Wireless → Wireless Settings. - Look at the field

Optimal channel settings for 2.4 GHz and 5 GHz
Besides the range, the speed is affected by the choice channelIn urban areas, 2.4 GHz channels are often overloaded, and on 5 GHz it is important to avoid DFS channels (they can cause connection drops).
| Range | Recommended Channels | Channels to avoid | Notes |
|---|---|---|---|
| 2.4 GHz | 1, 6, 11 | 2–5, 7–10 | These channels do not overlap. In Russia, use of up to channel 13 is permitted, but channels 12 and 13 can cause interference. |
| 5 GHz (low range) | 36, 40, 44, 48 | DFS channels (50–144) | DFS channels can be automatically switched off when radars are detected (for example, at airports). |
| 5 GHz (high band) | 149, 153, 157, 161 | 165 (may not be available) | The upper channels are less crowded, but some devices do not support them. |
To change the channel to TP-Link:
To analyze channel load, use the following programs:
- 🖥️ WiFi Analyzer (Android)
- 🍎 NetSpot (macOS/Windows)
- 📱 AirPort Utility (iOS)
Common problems when changing frequency and their solutions
Difficulties may arise after changing the range. Let's consider typical scenarios:
- 🔌 Devices are not connecting to 5 GHz.:
Check the compatibility of your gadget. For example, iPhone 4S And Samsung Galaxy S2 don't support 5 GHz. Solution: leave the 2.4 GHz network or buy an adapter (e.g. TP-Link TL-WN823N).
- 📶 Weak signal at 5 GHz:
The 5 GHz band has a harder time penetrating walls. Solution: Place the router closer to your devices or use Mesh system (For example, TP-Link Deco).
- 🔄 The router constantly reboots:
This may occur when selecting DFS channels on 5 GHz. Solution: Manually set channel to 36, 40, 44, or 48.
- 🔒 Settings are not saved:
Reset the router to factory settings (button
Resetfor 10 seconds), then repeat the setting.
⚠️ Note: On some models TP-Link (For example, Archer C7) When you enable 5 GHz, the guest network is automatically disabled. Check your guest access settings after changing the frequency.

FAQ: Answers to Frequently Asked Questions
Is it possible to use 2.4GHz and 5GHz on one router at the same time?
Yes, if your model supports it dual range (For example, TP-Link Archer C6 or Deco M9 Plus). In the settings, select the option Both (2.4GHz + 5GHz) or activate Smart Connect (automatic device distribution).
Please note: Some budget models (eg. TL-WR840N) work only at 2.4 GHz.
Which band is better for online gaming: 2.4GHz or 5GHz?
Definitely preferable for gaming 5 GHz, because:
- Less interference from neighboring networks.
- Lower ping (latency).
- Higher bandwidth (important for multiplayer shooters).
Exception: If your PC or console (PlayStation 4, Xbox One) is located far from the router, and the 5 GHz signal is weak, use 2.4 GHz, but choose the least crowded channel (1, 6 or 11).
Why do some devices not connect after switching to 5GHz?
This is because incompatibilitiesDevices released before 2012–2015 often only support 2.4 GHz. Examples:
- iPhone 4/4S, iPad 2/3
- Samsung Galaxy S2/S3
- Most smart light bulbs (Xiaomi Yeelight, Philips Hue first generation)
- Some TVs (LG 2013–2015)
Solution: Leave the 2.4 GHz network enabled or purchase a dual-band adapter for the problematic device.
How can I restore my old settings if I lost my internet connection after changing my frequency?
If you have lost access to your router:
- Connect to it via cable (via port
LAN). - Open the web interface at
192.168.0.1. - Restore the previous settings in the section
Wireless mode. - If it doesn't work, reset the router using the button
Reset(hold for 10-15 seconds).
After resetting, login/password will become admin/admin, and the network settings will be reset to factory settings.
Does Wi-Fi frequency affect internet speed from a provider?
No, Wi-Fi frequency affects only local network between the router and devices. The speed you get from your provider depends on your plan and connection type (e.g. 100 Mbps via cable or 500 Mbps via fiber optics).
However, if your tariff is - 300 Mbps, and the router operates at 2.4 GHz with a channel width 20 MHz, the actual Wi-Fi speed will not exceed 70–100 Mbps due to standard limitations. To fully utilize the plan, switch to 5 GHz with a channel width 80 MHz.
