Any Wifi Neighbors near by? If so, how many?

    Channel for the 2.4 wireless is Auto (9).

      What devices do you have all connected?

      Try setting manual channel 1, 6 or 11 on 2.4Ghz

      Does the front LED on the modem for 2.4Ghz turn OFF when this happens?

       

      Has a factory reset and setup from scratch been performed since last FW update?

        I have set the channel to 11 on the 2.4 wireless as per your advice.

        The 2.4 light remains on; to look at the modem/router, you would not know there was an issue.

        The FW update was performed on initial set up last year. This is the second CAX80 I've had, the first one was returned under warranty.

        I was under the impression that a factory reset was a last-ditch effort, if all else fails. Is that true?
