This Article Applied to:
Archer BE400_V1_1.2.3 Build 20260107 rel.48335
Archer BE6500_V1_1.2.3 Build 20260107 rel.48335
Phenomenon:
We have received user feedback indicating that after updating the BE400/BE6500 firmware to version 1.2.3 Build 20260107 rel.48335, Wi-Fi fails to function correctly if only one of the Wi-Fi bands is enabled. Specifically, if the 2.4 GHz band is disabled, it is impossible to connect to the 5 GHz network. Conversely, if the 5 GHz band is disabled, it is impossible to connect to the 2.4 GHz network. Wi-Fi connectivity works properly only when both the 2.4 GHz and 5 GHz bands are enabled simultaneously.
Available Solution:
The cause of this unexpected behavior has been identified, and our R&D department has released a beta firmware version that our user ashish7adlakha has verified to correct this anomaly.
If your Archer BE400/BE6500_V1 device also experiences this anomaly after updating to version 1.2.3, please try manually downloading the firmware and checking if the beta firmware helps:
