Troubleshooting WIFI 6 Mediatek MT7921 Card Issues

Troubleshooting WIFI Issues on Windows Computers

As avid Windows users, we’ve all experienced the dreaded "no internet access" symbol popping up in the system tray – a clear indicator that something has gone wrong with the WiFi connectivity. A spotty internet connection can disrupt both work and play. But before you panic, know that most WiFi problems can be easily fixed with a few tried-and-tested solutions.

In this comprehensive guide, we’ll walk you through some key troubleshooting steps to get your Windows machine back online.

Identify the Root Cause

Pinpointing the exact cause of the connectivity issue is the first step towards resolving it. Here are some questions to ask yourself:

• Is it a problem with just your computer or the entire network? Try connecting other devices to the network. If they can connect fine, then the issue is local to your machine.

  Why is my MediaTek card posting error reports in Windows?

  Now the Mediatek card is posting error reports in Windows and the network troubleshooter indicates a potential problem but not specific. I just feel PC makers use cheaper quality Wifi cards in some laptops to save money. But I have also noticed a lot more WiFi issues as we transition into multiple bands for WiFi.

• Have you recently made any hardware changes like switching WiFi cards or installing new drivers? Hardware conflicts could be preventing the system from talking to the router.

• Did the problem start after a Windows update or software installation? Newer drivers or OS upgrades can sometimes bug out the WiFi.

• When did you last reboot your router and computer? A simple restart can work wonders in many cases!

Update or Reinstall Drivers

The drivers essentially act as interpreters between the Windows OS and the underlying hardware. Outdated or corrupt drivers are a leading cause of WiFi connectivity problems. Here’s how to update them:

• Open Device Manager, expand Network Adapters, right click on the WiFi driver and select Update driver. This fetches the newest driver version.

• If updating doesn’t work, uninstall the driver altogether from Device Manager, reboot the machine and let Windows automatically reinstall it.

• For proprietary drivers like MediaTek, Intel or Realtek WiFi ones, get the latest versions from manufacturers’ websites and perform a manual install.

Toggle Airplane Mode On and Off

Airplane mode disables all wireless connectivity – WiFi, Bluetooth and cellular. Toggling it quickly essentially restarts the connections and can kick a buggy WiFi back into action.

How do I fix WiFi not working on Windows 11?

Navigate to the file that you unzipped earlier (Lenovo Wi-Fi 6 driver). The MediaTek-FORCED-10×64-7961_3.00.01.1309 Wi-Fi 6 driver will be installed on your Windows 11 PC. This fix has worked for the majority of users and will most probably work for you too. Move on to the next fix if the WiFi is still not working on your Windows 11 system.

Does mt7921 card have problems with Wi-Fi connectivity?

This card will have problems with Wi-Fi connectivity where throughput will be very slow in a single direction (transmit or receive). I have said MT7921 card in my Asus Zephyrus M16 that I have since replaced with both an Intel AX200 and AX210.

• Open Action Center and press the Airplane mode button to turn it on. Give it 5-10 seconds.

• Now turn Airplane mode off. This will re-enable all wireless radios.

• Try connecting to the WiFi again. Airplane mode cycling refreshes all connections and often resolves minor software glitches.

Forget and Reconnect to Network

Over time, saved WiFi network profiles can get corrupted and cause intermittent drops. Forgetting the network forces Windows to recreate the profile and reconnect.

• Go to Settings > Network & Internet > Wi-Fi.

• Click Manage known networks.

• Select the problematic network and click Forget.

• Reconnect to the network by entering the password again.

This simple step resolves connection issues in many cases without the hassle of troubleshooting drivers or hardware.

Change Router Channel

In densely populated areas with too many WiFi networks, interference and channel clashes can weaken signals. Changing the router’s broadcast channel might help.

• Log into the router admin console and go to Wireless or WiFi settings.

  Why does my MediaTek router Ping a lot?

  The MediaTek driver has a roaming issue, where it scans the channels even when your signal is very strong, thus causing ping spikes. I disabled roaming today and the issues are gone. Even “medium-low” was causing problems. May explain why when you’re sitting next to the wifi router it stops looking for a better signal.

  Why is my mt7921 so slow?

  It appears the MT7921 has been coded to try to stick to the highest possible Wi-Fi speed at all times, so anytime the signal is less than perfect, the performance drops off a cliff as packets just get lost over the air. Here’s an MCS rate table…

• Select a different channel from the list (1, 6 or 11 are safest).

• Save settings and reconnect devices to the network.

This forces the router to transmit data over a clearer channel, eliminating any possible interference issues.

Replace WiFi Hardware

If all else fails, the problem may lie in a faulty network card/adapter. Updating drivers and tweaking software settings can only go so far if the hardware itself is malfunctioning. Some signs pointing to a hardware fault include:

• Frequent disconnections and very slow speeds.

• OS not detecting the WiFi card.

• WiFi card overheating.

Diagnosing a hardware issue requires professional help. But an easy fix is to just replace the network card with a new one. USB WiFi adapters are inexpensive and plug-and-play too.

When to Call an Expert

While most WiFi problems can be addressed with simple troubleshooting, sometimes the issue may lie in faulty router firmware or complex incompatibility between devices. If you’ve tried every solution to no avail, don’t bash your head against the wall – call your ISP or a computer technician. A professional can analyze the root cause through technical tools and resolve the issue permanently.
