Intel AX200 Wi-Fi 6 Low Speed Issue and Troubleshooting (MSI X570 GAMING PRO CARBON WIFI)

[CrossBench]

Hello,

As I mentioned in the title, I have an MSI X570 Gaming Pro Carbon Wi-Fi motherboard. This motherboard uses Intel's AX200 Wi-Fi 6 network adapter.

I have a 1000 Mbps internet connection at home, and based on the speed tests I performed on the 5 GHz network with my phone and laptop, I can easily see speeds above 800 Mbps. My ping values range between 2 and 10.

However, from the same location in the house, when I test on my desktop computer, I occasionally see speeds around 250 Mbps (with ping between 2 and 10), but most of the time, I get results around 50-150 Mbps (with ping over 30). It's unlikely that there’s an issue with the device provided by ISP since all my other devices work flawlessly.

I’ve tried different versions of Wi-Fi drivers and applied many settings suggestions I found online through Device Manager. Unfortunately, I haven’t been able to solve the problem.

I’m awaiting your help. Thank you.

Answers can be in Turkish or English.

I always use the latest versions of drivers and Windows. My internet provider is Türk Telekom (1000 Mbps). I don’t experience any disconnection issues with my internet. My modem is a Zyxel EX3501-T0. While all my devices at home reach speeds of +800 to +900 Mbps, my desktop computer fails to achieve these speeds. I should also mention that I conducted the tests from the same location in the house.

I’ve checked the antennas on my computer, and there doesn’t seem to be any problem with their installation. There is no third-party traffic management software or VPN installed on my computer. Even after testing with a completely fresh Windows installation, I cannot achieve the same speeds on the 5 GHz network as I do with my other computers and phones.

Hello CrossBench,

Thank you for providing the necessary details. With that being said, I would need more time to further investigate the issue being encountered. I will get back to you once I have come up with an appropriate resolution.

I sincerely appreciate your patience and understanding.

Hello CrossBench,

Upon further investigating your SSU Log, I have noticed that you are using our Generic Driver. With that being said, I highly advise for you to download your OEM Driver, ⁠23.40.0.4 and perform a Clean Installation of Wireless Drivers as your device manufacturer may have altered features, incorporated customizations, or made other changes to some components for better compatibility with your system. 

If the issue persists, kindly let me know.

I look forward to your response!

Sorry for my late response. The drivers have been tested with the versions you requested, but there is no change. For days, it feels like there is a limitation on the WiFi, as I have been getting speeds between 300-400 Mbps.

Hello Crossbench,

Thank you for the update and for testing the recommended driver. I appreciate your patience as we work on identifying the root cause. 

To further investigate, kindly answer the following questions:

• What connection are you currently connected to? Is it the 2.4GHz connection or the 5 GHz connection?
• Have you checked if there are firmware updates for your router?
• I noticed that with your initial query, you were reporting occasional speeds of 250 Mbps and frequent results from 50-150 MBps. But not, you have mentioned that you have 300-400 Mbps speed with the OEM Driver downloaded. Is this consistent or does it change from time to time?
• With wired connection (LAN), what would be the Internet Speed?

I look forward to your response!

I am connected to a 5 GHz network. On a wired connection, I can achieve speeds around 900-1000 Mbps. I always strive to use the latest versions of devices and software. When I first mentioned the issue, my connection speed was slower than it is now (50-150-250 Mbps). However, I performed a clean Windows 10 installation again. It showed some improvement, but I can't say it solved the problem. I have added the Speedtest result I obtained with the 23.40.0.4 driver here. I also tested with the new driver, 23.110.0.5, and added that result here as well.

Let me also share the test result of my phone, which is connected to the same network and at the same distance.

Hello CrossBench,

Just to clarify, in your post, you mentioned achieving speeds of up to 1000 Mbps with a ping of 5-10 ms. At that time, were you connected via a wired or wireless network?

My wired connection test usually results in around 900 Mbps with 1-2 ms latency. In my 5 GHz wireless tests, my other devices at home (laptop and phone) easily achieve speeds between 800-900 Mbps, as seen in the attached file above. However, my desktop computer (x570 - Ax200) on the 5 GHz network never exceeds the speeds shown in the tests I shared earlier.

[RobbieR_Intel]

Hello CrossBench,

Thank you for sharing additional information. I understand that your other devices reaches the expected speeds of 800-900 mbps, while your PC, does not. However, I did note that once you have updated to the designated OEM driver and after performing a Clean Installation of Windows 10, both results showed that the speeds has improved to 300-400 mbps from the initial 50-250 mbps on the time you created this thread.

I would like you to try this: The network functioning will depend on your overall network configuration, you can follow these recommendations to improve the performance:

• Confirm you are using the latest wireless drivers for your specific system. You can visit your system manufacturer website (recommended) or use the Intel generic drivers available in our download center.
• Use the recommended settings for your wireless adapter. You can also visit Recommended Settings for 802.11ac Connectivity and Recommended Settings for 802.11ax Connectivity.
• Test the different bands available (2.GHz, 5GHz)
• Verify that your whole system configuration is compatible and supported (If you are using an AC router with an AX card you may not be able to achieve all the features available for AX connectivity). 
• Check with your router/modem manufacturer for firmware updates.

If you have further questions, please let me know so that I may further assist you.
