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....

Routers run better if you reboot them everyday. You can setup your router to reboot everyday at 4am in the ASUS UI.

I have gone as far as purchased a Meross Smart Plugs that turns my routers off at 4:00am and back on at 4:01am.

I also purchased a notebook fan for my routers that reduce the router temperature by 15c hence my network runs super smooth everyday.

My Gateway and APs reboot on updates only.

Ubiquiti AP:

...and an Asus router I support remotely:

If untouched they'll go as long as there is power. The expected behavior.

If you need to reboot your router every day - something is wrong with it.

Here is another Asus router (forgot about it):

...and one of the wireless devices connected to it (whatever it is):

It runs better if you reboot your router every day. A router is a computer; if you leave it on for weeks, it will run very well but not excellent!

Every time the power goes out then back on when I'm at a hotel overseas, the internet runs so fast until a couple of days later, the net slows down very little. After a good month, it would take 2-5 seconds after clicking on a link.

With my router setup, if I click on a link, it loads instantly. If I left my router on for a week, it would take a second or two after clicking on a link. Time is money!

I also do a factory reset every 6-12 months for my routers. I used to do the same thing for my PC back in the day. Nothing was better than a fresh version of Windows installed. I find routers work the same.

When I sometimes play an FPS game, I usually reboot my fibre, router and PC. That split-millisecond is everything in an FPS game.

Disconnecting from Wifi after a long time and reconnecting will give you better speeds and faster loading of websites, as you should know. Same with a VPN. I always disconnect my VPN then reconnect before watching a show on Movieboxpro or I can have buffer issues.

His ISP device is in a bridge mode so it doesn't route, it's only a modem. There is no NAT, no port forwarding, no DMZ, no firewall, no PPPoE. It is a pass through device, everything happen on the router itself.

It is quite a different information how long is router running without the restart and how often the connection has been dropped. This information is important only if the router restarts itself due some technical issues. There are many reasons why connection might be dropped. For example, every ISP drops the connection due transferred data amount monitoring, it's ususally an interval between 1 and 10 days. Then, there might be also some regular maintenance restart on ISP side. The last category is the issues on the router side (usually a wrong configuration or device failure). Current modern routers have enough resources that they can run continuously for a long period of time, no restart is necessary. These planned restarts work usually as a workaround when admin cannot find the root cause of existing issue. You cannot compare router with PC. There is one and only common rule, they both run slow when configured wrong. But correctly set router can run smoothly for years (of course with applying all updates and security solutions).There might be also the situation, that the router is targeted to a smaller network size (less clients) than it is used. This is usually the hotels overseas issue. Then the restart is also only a workaround here, but doesn't last too long.

I know. Switching it back to router mode is a common workaround for Asus routers losing WAN connection. We have discussed this many times with few different options available.

With my router setup, if I click on a link, it loads instantly. If I left my router on for a week, it would take a second or two after clicking on a link.

Sorry, your router has some issues. Rebooting it every day to keep it working the way you want it is a band-aid solution to underlying issue deteriorating normal operation over time.

You can try replacing the wall wart power supply. Those do fail after a while.
