Tags: #Firmware Update
Model: Archer BE550  
Hardware Version: V2
Firmware Version: 1.3.1 Build 20260403 rel.18661(4B52)

With my previous router, I consistently achieve approximately 900 Mbps download and 700 Mbps upload speeds.

 

However, when using the BE550 running firmware version 1.3.1 Build 20260403, download speed remains around 900 Mbps, while upload speed drops significantly to approximately 100 Mbps.

 

I tested the issue on multiple PCs as well as a Samsung Galaxy S25, and the upload speed remained consistently low across all devices.

 

I also performed a factory reset and configured only the Wi-Fi password before retesting, but the issue persisted.

 

After downgrading to the beta firmware version 1.3.1 Build 20260303 rel.49110(4B52), upload speeds returned to normal, indicating that the problem appears to be related to firmware version 1.3.1 Build 20260403.

Hello @FerociousSkate ,

Welcome to our community.

 

Have you enabled the QoS feature? If not, please enable it and configure the QoS bandwidth to the correct number that is subscribed from the ISP side.

To help you efficiently, I've forwarded your case to the TP-Link support engineers, who will reach out to you using your registered email address later. Please keep an eye on your email inbox for follow-up.

 

Best Regards.

  @Joseph-TP Please understand that I am using a translator.

I am currently on a 1Gbps plan. With the previous firmware version 1.2.6, my speeds were completely normal. However, just like mentioned in this thread, I experienced the exact same issue after updating to version 1.3.1. Even when connecting only my desktop directly without any QoS settings, the upload speed drops significantly.

In the end, I had to use recovery mode to downgrade back to version 1.2.6, and after the downgrade, my upload speed went back to normal
