January 31, 2024 at 8:34 pm #30349Welcome, as this update includes several security improvements, I would suggest an upgrade is advisable.
I have not seen any negative feedback regarding this new firmware release for the ASUS XT8.
remember to take a backup of your current configuration before you upgrade, just incase this new XT8 firmware release proves to be unstable and you have to revert back

February 2, 2024 at 8:23 am #30355I have updated to the latest firmware but have noticed since then in the system logs this happened loads. No idea what it means but have just submitted feedback/question via the interface. it is set manually to channel 1 as auto knocks the connection to the ring doorbell off otherwise.
Has anyone else noticed this?

February 2, 2024 at 9:23 am #30356Maybe they reduce bandwith to 20MHz, for 40MHz you need central channel 3.

February 2, 2024 at 9:27 am #30357I believe this is referencing channel 1 at 40MHz then switching to channel 1 at 20MHz
try changing bandwidth from Auto to Manual 20MHz if the message annoys you.
There is a cmd to tell you what Eth4 relates to but am out and about at the moment and will find it later.

February 2, 2024 at 9:32 am #30358Ok, An Update:
i have taken the plunge and upgraded my two XT 8 to 3.0.0.4.388_24609.
At the moment all seems to work fine, Noticed my WIFI throughput is a bit lower then expected (5G-2), Enabled the 160MHZ.
