Asus Tuf AX6000 disconnections

[ronins]

My Experience with the ASUS TUF AX6000 Router​

Recently, I purchased the ASUS TUF AX6000 router to replace my old one, which had worked flawlessly for years without any issues like disconnections.

My Setup​

I have tried two different configurations that ASUS provides: Wireless Router Mode and Access Point Mode.

1. Network Configuration (Wireless Router Mode):
   • My provider's modem/router (fiber connection) is connected to the internet.
   • I connected an Ethernet cable from the first LAN port of my provider's router to the WAN port of the ASUS router. i wanted to different subnets.
   • My provider's router has an IP of 192.168.1.1 with DHCP enabled, assigning IPs(dhcp pool) in the range of 192.168.1.3 to 192.168.1.250.
   • The ASUS WAN IP is configured as static:
     • WAN IP: 192.168.1.2
     • Subnet Mask: 255.255.255.0
     • Gateway: 192.168.1.1
   • The internal LAN of the ASUS router is configured to use the 192.168.2.x subnet:
     • LAN IP: 192.168.2.1
     • DHCP Range: 192.168.2.2 to 192.168.2.250
   • The ASUS router’s DHCP service is enabled, and both 2.4GHz and 5GHz wireless radios are active.
   • IPv6 is disabled.

Everything works perfectly for 15–20 hours, but then a disconnection occurs without any apparent reason. Below is the relevant log entry:

Dec 15 05:55:55 kernel: mtk_soc_eth 15100000.ethernet eth1: Link is Down
Dec 15 05:55:58 kernel: mtk_soc_eth 15100000.ethernet eth1: Link is Up - 1Gbps/Full - flow control rx/tx
Dec 15 05:55:59 WAN(0) Connection: WAN(0) link up(1000).
Dec 15 05:55:59 rc_service: wanduck 1218:notify_rc restart_wan_if 0
Dec 15 05:56:04 kernel: _nvram_free: 1(init) nvram_idx(0 / 2)
Dec 15 05:56:05 wan: finish adding multi routes
Dec 15 05:56:05 miniupnpd[2231]: shutting down MiniUPnPd
Dec 15 05:56:05 : it is advised to use network interface name instead of 192.168.2.1/255.255.255.0

The disconnection usually happens during periods of low traffic when I’m not actively using the internet. Interestingly, the first two days, the disconnection occurred at the exact same time +-1h each day.

Troubleshooting Steps Taken​

1. Profile Adjustment:
   I contacted my provider, and they informed me that my profile was set to IPv6-only. I requested a change to IPv4-only for testing purposes, but the disconnection issue persisted (at a different time of day).
2. Access Point Mode Configuration:
   I reconfigured the ASUS router as an Access Point:
   • The Ethernet cable from my provider's router was connected to one of the ASUS LAN ports instead of the WAN port.i abandon the idea of two subnets and i tried to use just one for all the devices.
   • ASUS Router IP: 192.168.1.2
     • Gateway: 192.168.1.1
     • Subnet Mask: 255.255.255.0
   • DHCP is managed by the provider’s router, using the range 192.168.1.3 to 192.168.1.250.
   • DHCP on the ASUS router dosnt exist as option
   • Everything seemed fine initially, but after another 15–20 hours, the disconnection occurred again. The relevant log is below:

Dec 16 08:46:22 kernel: _nvram_free: 29807(firmware_check_) nvram_idx(0 / 2)
Dec 16 08:47:17 kernel: 7986@C00L1ra0,RRM_PeerNeighborReqAction() 880: snprintf error!
Dec 16 09:04:29 kernel: mt7530 mdio-bus:1f lan1: Link is Down
Dec 16 09:04:32 kernel: mt7530 mdio-bus:1f lan1: Link is Up - 1Gbps/Full - flow control rx/tx

the provider's router logs did not show any errors. However, during the disconnection, the ASUS router seemed unable to communicate with the provider’s router, as all ping attempts failed. The connection only resumed after unplugging and reconnecting the Ethernet cable to the ASUS router.

I have only one disconnection every day

Next Steps​

1. Factory Reset:
   I performed a factory reset on the ASUS router and reconfigured everything. Note that the factory reset did not revert the firmware to its pre-installed version. The current firmware is 3.0.0.4.388_33427-gc525e4e.
2. Replace Ethernet Cable:
   I have ordered a new Ethernet cable to replace the one connecting the ASUS router to the provider's router. This is the only remaining hardware component that might be causing the issue.

Any ideas to check / test?

thnks in advance

+ from asus site i see aslo this firmware
ASUS TUF-AX6000 Firmware version 3.0.0.4.388_33419
can i download it and do a fw downgrade or it will create more problems?

It could be a UPnP conflict if the inside router has it enabled.

What you should do is copy the settings of the Isp router into the asus router and just use that, or if the Isp's router is the ONT device as well, have it bridged out. Sometimes you can do this in your webgui of it, other times the Isp does this remotely when you call them.

In the meantime, you should be able to disable the NAT-PMP modules that are causing the NAT hiccup.

well i need both routers to be connected each other. from asus gui the choices that i have are
wireless router modem
repeater mode
AccessPoint
Media Bridge
AiMesh

right now i am using it as access point.
I was monitoring the router, and it disconnected again.
There doesn’t seem to be any overheating issue because the CPU usage was only around 5%, and memory usage was at 50% at the time of the disconnection.

lan1 is the port that is used for connecting provider's router with the asus router.
lan4 is for the home alarming system that i use

because i use the asus router as access point there isn't any configuration/option for enabling/disabling the upnp .( this options exists only when u are using the asus router as "wireless router modem"
on the providers router the upnp is enabled.
the guide is helpful only for the "wireless router modem" setup
