Solution The 160MHz Option of 5GHz Disappeared on Archer AX50 After Updating Firmware to 1.1.1
This Article Applied to:
Archer AX50_V1_1.1.1 Build 20250917
Phenomenon:
Dear Archer AX50_V1 users, we recently released a new firmware for the Archer AX50_V1. This firmware introduces new parental control features and enhancements for the Archer AX50. It is undoubtedly good news for Archer AX50 users.
However, we've received feedback from some users that the 160 MHz option for the 5 GHz channel width has disappeared.
After prompt feedback, we've quickly identified the cause, and our R&D department has released a beta firmware update to address this unexpected behavior.
Available Solution:
If your daily network operations don't require manually setting to 160 MHz, you can choose not to update to this beta firmware for now.
For users who need to select 160 MHz in the daily network manually, please manually download the firmware and test whether this fixes the unexpected behavior.
