Hey Everyone,

Some users have reported a performance degradation in their Archer Routers after recently updating their firmware and enabling QoS. Specifically, Bufferbloat test scores for both wireless and wired clients have significantly decreased (e.g., from A/B to F). One of our Community Members, Serbian_Fantom, mentioned this unexpected behavior in this thread.

Additionally, a noticeable increase in upload latency may occur, resulting in higher latency and jitter when the network is under heavy load. Disabling QoS can resolve the aforementioned performance degradation.

Our Teams have identified the cause of these unexpected behaviors. Affected users with the Archer Router models below are encouraged to try one of the following solutions.

Applies to: 

Archer BE230_V1/V1.20
Archer AX55_V1
Archer AX55 Pro _V1
Archer AX72_V1
Archer AX72 Pro_V1

Available Solutions: 

Solution 1:

Our development team has provided the following beta firmware to address this unexpected behavior for the models that have already been reported. Please install the corresponding beta firmware for your router if you encounter this anomaly.

Note: 

• Pre-release and Beta firmware should be used at your own discretion. We cannot guarantee the functionality of features or technical support for Pre-Release or Beta Firmware. 
• If you are not comfortable using beta firmware, please wait for the official fix or contact our support teams for assistance.

Solution 2:

If you don't want to try the beta firmware, you can temporarily disable the QoS feature and wait for the next official firmware update.

Additional Information

As always, we value your feedback. If you happen to encounter any concerns during or after the router firmware upgrade, please feel free to comment below with the following information. Your input helps us continue to improve and provide the best possible products and support.

• Provide a detailed network layout, including how the devices are connected.
• Include a detailed description of the behavior and as much information as possible regarding the specific conditions that seem to trigger it.

What if your router model isn't among those mentioned above, but you've also experienced unexpected bufferbloat and high latency after enabling the QoS feature during firmware updates? 

• Please provide your router model, including firmware and hardware versions.
