RT-AX88U Random Internet/WAN Disconnects

[Zedd73]

I recently purchased an Asus RT-AX88U router and immediately upgraded the firmware to Merlin 388.1 before setting it up.

Since installing this router (which replaced my RT-AC68U) I have been having intermittent internet/WAN drops, that require either a disconnect/reconnect of the WAN cable or a router reboot. I also have a static IP from my ISP (if that helps). I have seen a few posts on this subject but haven't seemed to find any fix as of yet.

Has anyone figured out how to resolve this issue?

I really like the speed and range over my old router, but for a newer router that got high reviews across the web, I am surprised that this issue even exists.

Appreciate any help!

That's the worst router I ever owned.

Can you show what your logs say? I was having a similar issue, with constant wan down, i had to switch off the network monitoring option, and that did the trick for me...

Can't find exactly in the miles long log where the WAN drop occurred (will pull that info next time it happens), but did check on network monitoring and it was off by default according to the System Tab under Administration.

I had a similar issue, random WAN disconnects when I came across this thread https://community.virginmedia.com/t...ectly-quot/m-p/4329858/highlight/true#M304343 .

My error was Your ISP's DHCP does not function properly.

It looks like ASUS, sometime in 2020, made few changes and the WAN/DHCP query frequency should be changed to Continuous Mode if you experience WAN disconnects.

Here seems to be the solution https://www.asus.com/support/FAQ/1043591 from the above thread.

Thanks! I made that change and will see if that fixes the issue (although it hasn't dropped for a while now, so hopefully this will keep in from happening again in the future).

Isn't the WAN/DHCP query frequency option missing when the WAN connection type is set to static IP?
