Losing internet every 10 days or so with Telus ISP and RT-AX86U (Merlin 3004.388.8_4)

Home security, remote access.

You may have to forward the port it uses on the ISP device or simply place your Asus WAN IP in DMZ. Other option is to connect this home security to the ISP device if this is practical and doable. This way the remote access will be limited to ISP device network only with your network behind Asus firewall. You'll still have access to it from your Asus network. Just an idea how to use double NAT as network segmentation.

Restarted the ISP (Telus) ONT/modem/router (NH20A) and put in bridge mode on 10G modem port again, then rebooted RT-AX86U, it got a new WAN-IP and is staying very stable over the last week.

...or simply place your Asus WAN IP in DMZ...

Hmm, an interesting idea, DMZ of what? ISP device in a bridge mode or a Asus router?

Did not do that. Most direct path is ISP modem in bridge mode (10G port) and then letting the Ausus router do the NAT. ASUS router gets the DHCP automatically from the bridged modem.
In my case that now works well now with both iPv4 and iPv6.

Some others are not so lucky and have to use workarounds.

DMZ of what?

Your own router WAN IP in ISP router DMZ. Saves manual port forwarding, if needed.

Don't think it has anything to do with my ISP (Telus Fibre) with Network Access Hub - Arcadyan NH20A in Bridge mode.
I simply can't reach any websites anymore, no errors on router LOG, all devices still connected to the router and I can access the router interface via LAN...
I think it is the modem (in bridge mode) changing the IP address and the router staying on the previous public WAN IP.... so I am wondering what
changes I would need to do on the router, maybe setting up from scratch?
After a router reboot everything works again...

I was having the same issues with Shaw (now Rogers). My cable modem (Ignite WiFi Gateway Gen 3 modem XB8) in bridge mode and I would get random disconnects from the internet, nothing wrong with the cable modem. Just the router would lose the connection.

I created a script to fix the error

... not sure what I did on the router WAN settings but the WAN-IP from the ISP is super solid, rebooted the Asus router many times, changed all kind of DNS and DDNS settings, before I would get a new router WAN-IP each time I changed a setting, now even after a modem reboot (new IP on the modem side) the WAN-IP on the Asus router stayed the same... only after switching on iPv6, then off again, the Asus router WAN-IP changed... no clue how that works but the less frequent the router WAN-IP changes, the better for me....
