TUF-AX6000 disconnect the WAN every 12-14 min for just a few seconds

[eulfkar]

I replaced my old RT-AC3200 with a fancy TUF-AX6000, and since then the TUF-AX6000 disconnect the WAN every 12-15 min just for a few seconds.
I am not getting anywhere with ASUS support , they told me to go back to the store and get a new one after we have tried hard rest etc.

Same issue and every time the same message in the sys log

I have compared all the settings with my old RT_AC3200 and the only difference is some extra settings possibilities as below, the RT_AC3200 had only DNS auto.

Anybody has an idea what could be causing this??

Turn off the two DNSSEC options.

What firmware version are you using?

Turn off the two DNSSEC options.

What firmware version are you using?

3.0.0.4.388_31927, Which is the latest according to ASUS
DNSSEC turned off, No improvement disconnect WAN every 10-15min
Does it even in the middle of the night when no one is using internet?

 

[ColinTaylor]

Are there any other messages in the log just prior to those you posted?

Also look at the logs of the modem. There may be some indication of the problem there.

A couple of things you could try.

1) Power off your modem for 20 minutes and then turn it back on again.

2) Clone the MAC address of your old RT-AC3200 onto the TUF-AX6000. The MAC address of the RT-AC3200 can be found printed on the label on the bottom of router. Log on to the TUF-AX6000 and enter the MAC address at WAN - Internet Connection > MAC Address. Apply that change and wait for the router to reboot. Once the router has come back up power off both the router and the modem. Wait 2 minutes and power on the modem. Wait another 5 minutes before powering on the router.

There are a lot of "WAN(0) link down" messages in the log. This could indicate an ISP issue or a physical problem with the connection from the modem to the router (e.g. bad cable). Try changing the Ethernet cable between the modem and the router. Also look at the log on the modem.

Check your Internet Status: Click on the blue globe to the left of the Internet Status: Connected. An Internet Status panel will then show on the right. Check the Lease time which will show how often the WAN IP address will renew. Below that is a Lease Expires value. The IP address lease should renew when the Lease Expires value reaches half of the Lease time. For example, my Lease Time is 15 minutes and the lease renews when the Lease Expires reaches 7 minutes 30 seconds. If your lease does not renew like this you may have to change the WAN/DHCP query frequency.

Lease time 3 hours!

Lease time 3 hours!

I saw that, but there doesn't seem to be any correlation between that and your problem.

Another thing - check that you have IPv6 disabled.
