    I've bought ZenWiFi AC CT8 to improve my home wifi, but it's embarrassing how bad it is.

    It keeps resetting every few hours with hundreds of lines of oom-killer in its logs.

    That means that the operating system ran out of memory and has to start killing processes in order to free memory.

    This causes total network death - no wifi, some wired network traffic is lost too.

    I have to keep resetting it every time it happens.

    ASUS - Do something!

  • I have the same problem. CT8, a base and a satellite. The symptom is loss of internet. CT8 logs show cascades of out-of-memory errors. Cycle power, and it works for 10 minutes, or an hour, or a couple of days until it dies again.

    Gigabit fiber internet. About 40 devices (smart bulbs & switches, a couple of PCs, a couple of iPads). Heaviest usage is a couple of Netflix streams.

    Works fine as Access Point only. Rock solid as an access point. Worthless boat anchor when used as a router connected to the WAN. Pretty expensive boat anchor.

  • Same here, exactly, but a much simpler network.

    It's sad to see Asus top-of-the-line router fail on such a simple setup

  • Think I'm having the same issue...rebooting it seems to clear the issue for a couple days then watch the 250 megs of memory being taken. Agree for a top of the line router its bad.
