Using the right internet service provider is essential for a robust internet connection. But on top of everything, you need to use the right router because that’s the ultimate medium that’s going to provide the signals. That’s the most probable reason that people don’t compromise on the router quality. With a plethora of options in the market, it can be overwhelming to choose the right option,

In that case, people are using ASUS routers as they have promised to provide maximum internet speed. But people have been struggling with sluggish speed on ASUS router as well. This is why we have added some tips that will help achieve maximum internet speed on the ASUS routers. So, let’s get started right away!

ASUS Router Slow (8 Ways To Fix)

1) Wireless Spectrum

First of all, you need to analyze the wireless networks around your location through third-party apps. These apps will help you line out the congested and free WiFi channels. Using free or less congested channels will help optimize the fastest possible speed.

2) Choose The Right Settings

ASUS provides mobile apps to the users, who wish to manage their WiFi network through smartphones. However, the apps provide limited configuration settings. So, you need to use the router’s IP address and access the configuration settings on the webs browse. This will put you in contact with advanced settings, such as access points, connected devices, internet speed provision, and passwords.

3) Wireless Mode

When you are using the ASUS router, you need to choose the correct wireless mode. The wireless mode can be chosen through the Wireless category on the app. There are multiple modes available, such as;

  • Auto – This is the top-notch choice because it tops up the internet speed
  • N – This is optimal for 2.4GHz band and for the people who are using old devices
  • Legacy – If your devices are older than a decade, this wireless model will work for you
  • N/AC – This is optimal for 5GHz band with wireless routers

4) Channel Bandwidth

You need to choose the to-be-configured band from the general tab and look down on the bandwidth feel. There is 80MHz, 20MHz, and 40MHz bandwidths available and you can even create a combination of them. There are some areas with free wireless spectrums and that’s where you can choose the larger bandwidth.

5) Free Channels

First of all, you need to choose the right band to be configured and choose the free channel. Every area has some free channels but they tend to be congested. So, try to find the free yet less congested channels (either 24GHz or 5GHz) and click the enter button right away!

6) Multi-User MIMO

This setting will ensure that you are able to serve different clients at the same time with one router. However, the multi-user MIMO can be enabled for the 5GHz bandwidth. So, you might need to upgrade to use this feature if you are still stuck on 802.11n or 2.4GHz.

7) Beamforming

You need to switch on the explicit beamforming from the wireless section. With this setting, you will be able to direct the wireless signals in the right direction. With beamforming, you will be able to improve the signal reception without causing any signal interference. Also, it’s available for the 5GHz band users.

8) DoS Protection

If you’ve enabled this feature, there are high chances that it is sucking up the hardware sources. So, there are high chances that DoS protection is the real culprit. So, disable the settings from the web browser and the ASUS router is highly likely to improve the signal strength.

  1. I tried all this.

    What worked for me is to disable “ IGMP Snooping” for Sonos, AppleTV and other remote devices to work faster.

    Because of security I disabled UPnP (

    For real spread up I have put together this list of commands, that have to entered through SSH. One line is one command. Normally everything can be copy-pasted (start/finish between the #):

    ebtables –flush
    ebtables -A FORWARD -p IPv6 -j DROP
    ebtables -A OUTPUT -p IPv6 -j DROP
    ebtables -A INPUT -p IPv6 -j DROP
    ebtables -A INPUT -p IPv4 –ip-dst -j DROP
    ebtables -A FORWARD -p IPv4 –ip-dst -j DROP
    killall -q -9 mcpd
    brctl setfd br0 20
    brctl setfd br1 20
    brctl setfd br2 20
    brctl sethello br0 4
    brctl sethello br1 4
    brctl sethello br2 4

    Have to SSH into every mesh router. The username is admin, and password your router admin password.

    All the settings will be lost if you restart the router.
