How to Quickly Fix Extremely Slow Wi-Fi on Asus Laptops

Check here all the best methods available to quickly fix slow Wi-Fi on Asus laptops. Speed up your Internet connection now.

Many users report unstable or slow Wi-Fi connection on Asus laptops when comparing their Internet speed with other devices on the same network, so I gathered all methods that actually work to fix slow Wi-Fi issues on your Asus.

The most effective methods to fix slow internet on Asus laptops are:

  • Run Windows 10 Network Troubleshooter
  • Update your Network Drivers
  • Enable WLAN or WWAN AutoConfig on your PC
  • Tweak your Internet settings through CMD
  • Connect to the correct Wi-Fi standard

In this article, we will go through each one of these methods to find the cause of your Internet issues.

(If your Asus Laptop can’t detect your network or if you have a MediaTek Wi-Fi 6 MT7921 network adapter, I’ve written an article on how to fix Mediatek Wi-Fi 6 MT7921 card not working.)

Before starting, make sure to run Windows 10 network troubleshooter and update your network drivers.

If you have already tried these basic solutions, skip to the third method.

Fix 1: Run Windows 10 Network Troubleshooter

The network troubleshooter is a built-in Windows tool to help users diagnose and fix common Internet issues, so it is naturally the first step we should take when dealing with internet problems.

To run the Windows 10 Network Troubleshooter:

  1. Press Win + I to open Settings.
  2. Under Settings, click on Network & Internet.
  3. On Network & Internet, click on Status.
  4. Select Network troubleshooter under Change your network settings.
  5. Run the troubleshooter and check if it fixed your Internet issues.

Fix 2: Update your Network Driver

Another basic fix for internet issues, which works often, is simply updating your network adapter driver to the latest version.

You can update your Asus laptop network drivers using a driver updater to update all your device drivers at once or through the Windows device manager.

Keep in mind that updating drivers through Device Manager is not always reliable.

Here is how to do it through the Device Manager:

  1. Enter Device Manager on Windows Search, then click on Open:
  2. Now, find Network Adapters and click on it to see your network adapter.
  3. Right-click on your network card and click on Update Driver.
  4. Select Search Automatically for Drivers and wait for the process to finish.

If running the Network Troubleshooter and updating the network drivers didn’t work, move on to the next step.

Fix 3: Enable WLAN or WWAN AutoConfig on your PC

As explained on Windows’ official website, WLAN, or Wireless Lan, is a service that dynamically selects which wireless network the computer automatically connects to. While WWAN, or Wireless Wan, automatically configures mobile broadband data.

We will enable both services to ensure that Windows optimizes your Asus laptop’s slow Wi-Fi connection. Here is how you can do it:

  1. Press Win + R to open Services.
  2. Enter services.msc and click OK.
  3. Browse down the services list to find WLAN AutoConfig.
  4. Right-click on it and select Properties.
  5. Toggle Startup Type to Automatic.

    If it is already on Automatic, click on Stop under Service Status, then click on Start.
  6. Now go back and do the same for WWAN AutoConfig.

If this doesn’t work, move to the next step.

Fix 4: Tweak your Internet settings through CMD

Another possible solution is to run a series of commands on CMD that will reset and adjust your Asus laptop’s Internet settings. These commands are handy when fixing internet problems.

These are the following commands:

CMD CommandWhat it DoesBenefits
netsh int tcp set heuristics disabledDisable Windows Scaling heuristics.According to this blog, It prevents Windows from restricting your download speeds
netsh int tcp set global autotuninglevel=normalEnable Windows Auto-Tuning featureEven though some recommend otherwise, disabling Window Auto-Tuning won’t improve your Internet connection and will certainly make it slower.
netsh int tcp set global rss=enabledTurn on Virtual Receive-side scalingMicrosoft says that RSS improves network system distributing receive processing across multiple CPUs.
netsh winsock resetReset Winsock ConnectionsRecover your computer network from errors due to a malicious script on your PC
netsh int ip resetRemove and reinstall TCP/IP on your PCRewrites all TCP/IP registry entries
ipconfig /releaseRelease the IP addressSolve network connectivity issues related to cached IP information
ipconfig /renewRenew the IP addressSolve network connectivity issues related to cached IP information
ipconfig /flushdnsFlush the DNS CacheIt helps to fix internet connectivity problems.

It is not complicated to run them at all, just follow the step-by-step below as we run each command:

  1. Enter Command Prompt on Windows Search, then click on Run as Administrator:

    Make sure to select the Run as Administrator option, or you won’t be able to run some of the commands.
  2. Now enter the commands below Enter to run it:
    netsh int tcp set heuristics disabled
  3. Repeat the process with the following commands in the order below:
    netsh int tcp set global autotuninglevel=enabled
    netsh int tcp set global rss=enabled
    netsh winsock reset and press Enter
    netsh int ip reset and press Enter
    ipconfig /release and press Enter
    ipconfig /renew and press Enter
    ipconfig /flushdns and press Enter

(You can also try to do a network reset as we suggested in this article on Wi-Fi keeps disconnecting issues.)

Fix 5: Connect to the right Wi-Fi standard

Wi-Fi standards are different technologies of Wi-Fi that were implemented over the years. The current Wi-Fi technologies are Wi-Fi 4, Wi-Fi 5, and Wi-Fi 6. Each name corresponds to a different standard:

Wi-Fi 4802.11n
Wi-Fi 5802.11ac
Wi-Fi 6802.11ax
The different standards of Wi-Fi connection

It is crucial that your network adapter and your router use the same Wi-Fi standard. Slow internet can result from different Wi-Fi standards in your network adapter and router.

Identifying the Wi-Fi standard of your network adapter

For this, you need to know the name of your network adapter. If you already know it, you can skip directly to step 3; if not, check the specifications of the PC you bought or follow the steps below:

  1. Enter Device Manager on Windows Search, then click on Open.
  2. In the device list, find your network adapter (which will likely be under “Network adapters”) and check its name:
    How to open the properties of your Network Adapter
  3. Google your network adapter to find its product specifications and Wi-Fi standard:
    Find your Network Adapter wi-fi standard by googling it

Identifying the Wi-Fi standard of your router

You need to check your router device to find the name and model of your router. Then you can google its name to find the Wi-Fi specifications.

Configuring your network adapter Wi-Fi standard to be the same as your router

Now that you know the Wi-Fi standard of both your network adapter and router, do the following steps:

  1. Enter Device Manager on Windows Search, then click on Open.
  2. In the device list, find your network adapter, right-click on it, and select Properties.
  3. Under the Advanced tab, look for 802.11n/ac/ax Wireless Mode under Property:
    Where to find your Wi-Fi standard configuration on Network Adapter properties
  4. In Value, select the Wi-Fi standard supported by your router:

The methods above are the best way to fix a slow Wi-Fi connection on your ASUS laptop. If none of these work, you can still try to make a clean boot to detect what is causing the issue, or you can also try to disable Asus Smart Connect.
