Issue with Slow Download Speeds on Intel BE201 Wi-Fi Card

[AminAb]

Hello,

I recently purchased a laptop equipped with an Intel BE201 wireless card. I am experiencing a problem where the download speed is very low, while the upload speed is perfect.

I have tried all the troubleshooting methods suggested on Intel's support forums, but none of them have resolved the issue.

To confirm that the problem is with the internal card, I tested my internet speed using a separate wireless USB dongle on the same laptop. The speed with the dongle was excellent, which suggests the issue is specific to the BE201 card.

For your reference, I have also attached the system report generated by the Intel® System Support Utility (SSU).

Hello AminAb

Thank you for posting in Intel community Forum.

For me to better understand and diagnose the issue further, let me ask you to provide detailed responses to the following questions. This information will help me isolate the problem and determine the most appropriate course of action moving forward.

1. What is the brand and model of the laptop?
2. Let me clarify, did you purchase this system as a brand-new unit?
3. Have you tried other access point or wireless router? If yes, are you getting the same speed?
4. What are the troubleshooting steps that you tried so far?
5. For me to review the hardware and installed drivers, please help generate the SSU logs of your system. Kindly refer to the link below for the steps:

If you have questions, please let us know. Thank you.

Thank you for your prompt response.

As requested, please find my detailed answers below:

1. Laptop Brand and Model: Asus ZenBook UX3405CA

2. Purchase Status: Yes, I purchased it recently as a brand-new unit.

3. Other Access Points Tested: Yes, I have tried three different access points. All of them operate on the 2.4GHz band, and the slow download speed issue persists across all of them.

4. Troubleshooting Steps Performed: I have already tried several solutions based on my research in the forum:

   • Updated the wireless driver to the latest version available from the Intel website.

   • Also updated the driver from the Asus support website.

   • Performed a reset hardware components on the laptop.(community.intel.com/t5/Wireless/Wifi-driver-AX201-not-working/m-p/1563050#M51919)

   • Resetting Network Devices and Network Stack

   • Changed various wireless adapter settings and parameters to check for any improvement.

5. SSU Logs: As mentioned, I have already attached the SSU log file (send_to_intel.txt) to my initial forum post.

Given that the issue occurs on multiple access points and persists after extensive troubleshooting, it appears to be isolated to the laptop's hardware or its interaction with the 2.4GHz band. I would greatly appreciate it if you could analyze the provided SSU logs and advise on the next steps.

Thank you for your time and assistance.

Best regards,
AminAb

Hello AminAb

Thank you for the update.

Before we proceed, let me set the expectation that you are using an OEM system from a 3rd party manufacturer. Our support is limited since it is using 3rd party components. If our recommendations did not work, it is also best to contact the manufacturer of the system.

Please try to reinstall the latest driver using Clean driver installation method and update me if there will be changes.

Kindly refer to the link below for the steps and manual download of the driver:

If you have questions, please let us know. Thank you.

Dear Michael,

Thank you for your prompt response.

I fully understand the support limitations regarding my OEM system, and I appreciate you clarifying that.

To give you better context, the issue isn't that the hardware is completely non-functional. The main problem seems to be its unstable performance. It appears to be working, but inconsistently, which leads me to believe it might be related to a power-saving feature or a driver compatibility issue, rather than a total failure.

Regarding your recommendation, I have already tried a clean installation of the latest driver using the method you linked, but unfortunately, it did not resolve the problem.

Thank you again for your time and assistance.

Best regards,
AminAb

Hello AminAb

Thank you for the update and understanding.

There are a lot of possible reason for the issue, it could be the driver or BIOS. That is why it is best to do further test and isolation.

I checked the website of the laptop, and they have an OEM driver available. Here is the link:

ASUS Zenbook 14 OLED (UX3405)｜Laptops For Home｜ASUS Malaysia

Let me also explain the difference between Intel generic driver and OEM driver. Intel provides a generic driver that will work for most of the controllers using default setting/specs. However, OEM system manufacturer may alter, modify or enhance the controllers that they install on their system. And to enable those changes, they provide their own driver which is the OEM driver. Most of the time, the recommended if the OEM driver.

Going back to the issue, you may also try to contact Asus to further check if this is indeed a hardware issue. They are the best team who can diagnose the system.

If you have questions, please let us know. Thank you.
