Hello,

This is to confirm that last night I updated the firmware to version 1.7.1 Build 20260213 rel.87654 on my Archer AX53 and since then I have been facing the following issues:

• Wi-Fi range has significantly decreased. At the same distance, I am now getting slower speeds on Wi-Fi 6 devices while using channel 149 and 80 MHz channel width on 5 GHz. Previously, I used to get 800 Mbps+, but now I am getting around 400 Mbps. However, when I move very close to the router, I can still get 700 Mbps+.

• Wi-Fi range has also decreased on Wi-Fi 5 devices, and the speed appears capped at about one-fourth of the previous performance while using the same channel settings. On my gigabit internet connection, the speed now rarely exceeds 250 Mbps in the same environment. Previously it was 500 Mbps+ on the same device.

• The 2.4 GHz band is also behaving similarly with reduced range and speed.

• The web interface has become very slow and less responsive after the update.

Solutions I have already tried are as follows:

• Factory reset and reconfigured everything, but no improvement.

• Enabled and disabled QoS, but no improvement.

We would really appreciate a quick fix for these issues.

Thank you for your attention,
