I have a Zyxel EX5601-T0 with firmware V5.70(ACEN.0)b5 (the ISP doesn't update it to next versions and I didn't update it myself to avoid any kind of "definitive" issues).

Anyway, for some reason, every hour, at the same time (same minute every hour), I have a microdisconnection that lasts a few seconds.

The important thing to understand here is the modem doesn't restart (eg. the system activity time doesn't change).

I activated the logs and found, for example:

611 Nov 9 08:47:28 daemon debug dhcpd dnsmasq-dhcp: sendLeaseMessageToESMD esmd ret=1
612 Nov 9 08:47:28 daemon debug dhcpd dnsmasq-dhcp: sendLeaseMessageToESMD send to esmd buf = {"ac":"add","expire":"32491","mac":"edited_mac","ip":"192.168.1.6","host":"DESKTOP-EDIT","vendor":"MSFT 5.0","moui":"","serial":"","pclass":"*","cid":"edited_mac","ifname":"br0"}
613 Nov 9 08:47:28 daemon info dhcpd dnsmasq-dhcp: sendLeaseMessageToESMD

1 Nov 9 09:47:27 daemon debug dhcpd dnsmasq-dhcp: sendLeaseMessageToESMD esmd ret=1
2 Nov 9 09:47:27 daemon debug dhcpd dnsmasq-dhcp: sendLeaseMessageToESMD send to esmd buf = {"ac":"add","expire":"36090","mac":"edited_mac","ip":"192.168.1.6","host":"DESKTOP-EDIT","vendor":"MSFT 5.0","moui":"","serial":"","pclass":"*","cid":"edited_mac","ifname":"br0"}
3 Nov 9 09:47:27 daemon info dhcpd dnsmasq-dhcp: sendLeaseMessageToESMD
4 Nov 9 09:47:14 daemon err pppoe pppd: Unable to complete PPPoE Discovery
5 Nov 9 09:47:14 daemon warning pppoe pppd: Timeout waiting for PADO packets

Can you help understand what's going on here?

    Hello, maybe I found the reason for this issue: in the Wireless > Channel Status tab I found a Channel status monitor. In the same page, below, I found the time for the last scan and it coincides with that of the hourly disconnections.

    Now, I don't use the AUTO channel feature, so I don't see the reason for the scan. AND, I couldn't find a way to disable it or even change its frequency.

    By exporting my settings, I found an "AutoChannelRefreshPeriod" key in the JSON (is this related? Can it be changed?).

    Any suggestion is appreciated.
