2. Set the channel bandwidth to default

Channel Bandwidth will affect your wireless speed performance and signal stability. In default, the ASUS router will adjust the channel bandwidth automatically.

  • Band 2.4 GHz : Default channel bandwidth [20/40 MHz]。
  • Band 5 GHz  / 5 GHz-1 /  5 GHz-2 : Default channel bandwidth  [20/40/80 MHz]。
  • Band 6 GHz  : Default channel bandwidth  [20/40/80/160/320 MHz]。

Note:

(1)  Some functions of wireless will be different due to firmware version.

(2) Currently, you can only adjust the channel bandwidth from the ASUS router settings page (Web GUI).

 

Go to [Wireless] > [General], you can set the channel bandwidth for different frequency bands ( 2.4 GHz / 5 GHz / 5 GHz -2/ 6 GHz ) respectively.

Interface 1: Supports routers with firmware later than 3.0.0.6.102_35404 (including)

Interface 2: Supports routers with firmware earlier than 3.0.0.6.102_35404

Please refer to [Wireless Router] How to improve wireless speed by setting Channel Bandwidth in Wireless Router to learn more.

 

3. Switch to a control channel with less interference

If your router uses the same channel as other nearby wireless devices, it may cause interference and slow speeds.

The wireless channel of the ASUS router is default to [Auto], you can switch to a control channel with less interference.

Note:

(1) Supported channels of 2.4 GHz, 5 GHz and 6 GHz WiFi differ according to each country’s local law and restrictions.

(2) Some functions of wireless will be different due to firmware version.

(3) Currently, you can only adjust the control channel from the ASUS router settings page (Web GUI).

 

Go to [Wireless] > [General], you can set the control channel for different frequency bands ( 2.4 GHz / 5 GHz / 5 GHz -2/ 6 GHz ) respectively.

Interface 1: Supports routers with firmware later than 3.0.0.6.102_35404 (including)

(a). The following figure takes the band 2.4 GHz as an example, the default control channel is [Auto], and the current control channel is 2.

 Select a different control channel, and then click Apply to save.

(b). The following figure takes the band 5 GHz-1 as an example, the default control channel is [Auto], and the current control channel is 10.

 Please cancel [Auto select channel including DFS channels], and select a different control channel, and then click Apply to save.

 What is DFS channels? please refer to [Wireless Router] What is DFS (Dynamic Frequency Selection) and how does it work on ASUS router? to learn more.

Interface 2: Supports routers with firmware earlier than 3.0.0.6.102_35404

(a). Band 2.4 GHz

Select a different control channel, and then click Apply to save.

(b). Band 5 GHz

Select a different control channel, and then click Apply to save.

(c). Band 5G-2Hz, cancel [Auto select channel including DFS channels].

What is DFS channels? please refer to [Wireless Router] What is DFS (Dynamic Frequency Selection) and how does it work on ASUS router? to learn more.

Select a different control channel, and then click Apply to save.

 

4. Try to disable Smart Connect

You can set up your ASUS router via Web GUI or ASUS Router app.

Note: Some functions of wireless will be different due to firmware version.

Interface 1: Supports routers with firmware later than 3.0.0.6.102_35404 (including)

Turn off Smart Connect: You can set different WiFi names and passwords for different WiFi bands.

(1) For example, if you want to add a new 2.4 GHz WiFi band, keep 2.4 GHz, unchecked other WiFi bands, and then click [Apply] to save the settings.

(2) As shown in the figure below, the WiFi network is in the 2.4 GHz WiFi band, that is, the Smart Connect is turned off.

Interface 2: Supports routers with firmware earlier than 3.0.0.6.102_35404

Go to Wireless > General > Switch the button on [Enable Smart Connect] to off.

For the information of how to configure Smart Connect, please refer to [Wireless Router] How to configure the Smart Connect in ASUS Router?

 

5. Try to adjust the direction of the router's antennas

You can try adjusting the angle of the external antenna (e.g. 45 degrees, 90 degrees, etc.) to the optimal signal distance.

Below we take RT-AC88U for example, for other models, please refer to user manual.

To ensure the best wireless signal, set the four detachable antennas as below suggested image. Below we take RT-AC88U for example, for other models, please refer to user manual.

[Note] You can download the user manuals in the ASUS Download Center.

 

6. Adjust the placement of the router

It is recommended that the user can adjust the placement of the router, close to the wireless device client, and shorten the distance between the wireless router and the client, to avoid the distance of the signal transmission affecting the strength of the signal.

WiFi is distinguished into 2.4 GHz and 5 GHz, the 2.4G Hz signal transmission distance is farther than 5 GHz, but slower than 5 GHz, 5 GHz although the signal transmission distance is shorter, but the speed can be faster.

When your wireless device is often disconnected, you can first check that your wireless device is connected to WiFi (2.4 GHz or 5 GHz) and confirm the distance between the wireless device and the router when the WiFi is disconnected.

For the information,  please refer to the FAQ [Wireless Router] How to improve Wi-Fi Connection

 

7.Environmental interference

Make sure that no interference or barriers affect the wireless signal around the wireless router, and remove the interference and barriers whenever possible, or try to replace the location of the wireless router.

  • Interference: microwave ovens, refrigerator, wireless phones, power boxes... And so on, some home appliances will also produce interference with wireless channels.
  • Barriers: iron cabinets, iron doors, cement walls, closed cabinets, placed on the ground, behind the sofa. Some high-density building materials can also affect WiFi signal penetration, such as gypsum, planks, barbed wire, etc.

It is recommended that you place the router in the center of the environment where possible, in an open area, where there is less furniture, where there is no wall barrier, or on a wooden cabinet, on a tabletop.

 

8. Update the wireless device driver or firmware

Confirm that the wireless device driver or firmware you are using has also been updated to the latest version. Please contact your device manufacturer for any updates.

  • Wireless device: Such as Laptop, Smart Phone, USB WiFi Adapter, CONSOLE.
