RT-AX86U 2.4GHz radio fails

[David Arnstein]

My router has latest firmware 3.0.0.4.388_24231-gbc11d13 . It supports a mix of 2.4GHz and 5GHz clients, and it is also the "master" to another AX-RT86U acting as a wireless bridge.

The 2.4 GHz clients lose connectivity repeatedly. The frequency of these events is variable, days to weeks apart. Ethernet clients and 5GHz clients are not affected. Problem resolves after disabling and enabling the 2.4GHz radio in the "Wireless/Professional" tab of the web interface to the router.

I looked at the system log and the only relevant messages I could find include "Disassociated because sending station is leaving" and "Deauth_ind AC:CC:FC:E4:93:9A, status: 0, reason: Unspecified reason (1)". I am seeing a flood of messages in the log, so I could have easily missed something important.

Any suggestions?

Any suggestions?

Make the 2.4GHz band more compatible. Disable AX on it and try again. See more here:

I applied all of the settings highlighted in the Asus FAQ, the same day you posted this suggestion. Today, the failure occurred again.
