So, I am using a Linksys WRT1900ACS version 1 router. I am running DD-WRT v3.0-r63123 std (12/19/25).

Basically, every hour on the dot (00:00, 01:00, 02:00, etc) my client devices, while they are connected to the wifi (on both the 2.4ghz and 5ghz bands) end up disconnecting from the internet. They are connected to the wifi, but are unable to receive any internet signal, until they are manually disconnected and reconnected to the wifi

I attempted to upgrade to the above DDWRT build (from the 08/08/2025 build)to see if it fixed the problem. It did not.

What can I do to fix this? Is any more information required?

What is the status of the WAN when this happens?
Anything in the logs?

I have NTP sync interval set to 86400 (once per day). The wireless Group Key Handshake interval is still default 3600 (every hour). There is no controlling what client devices do. Only other thing to check is your wifi settings on the router.
