Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.3.0 Build 20250428 Rel.18967

Hi all,

 

I was now several days abroad and my ER605 on primary site was going mad.

1st two issues were relatively simple - the SDWAN link was going down - was back after rebooting router on the primary site via Android App (I was in vacation without notebook)

 

the 3rd issue was completely strange and I couldn't fix it remotely via app.

Symptoms:

  • SDWAN going offline (notified via monitoring)
  • DHCP down (all of my dynamic devices were offline after DHCP lease has expired)
    • OpenVPN was offline obviously because dead DHCP
    • thankfully  WireGuard was functional as it doesn't require DHCP
  • App showed the router "disconnected", which means, reboot command isn't available. 
    • Force Provision command without effect
  • Internet access and routing in general was OK (I could access the network and connect to controller via app using WireGuard)

 

I could restore the normal operation only by power cycling the router.

 

Any idea?

  @ZoloNN My ER605 V2 FW 2.3.0 has also been going down over the last week.  I have had to reboot it 3 times.  Nothing noted in the logs.  Slight CPU and memory spike just before going down.  Hopefully someone at tp-link is working on a fix, my family wants me to get rid of this router.

Hi @jg1212 

 

Are you using controller mode or standalone one?

You could reboot the device or powercycling was needed?

  @ZoloNN 

SD-WAN is down, so one of the sites as the Hub could be down. I assume.

 

I don't have a diagram of your network. I cannot pinpoint if it is a scheme issue. You can use this thought and continue the troubleshooting. 

Omada is pretty solid as far as I can see. SD-WAN should not be down without a reason.
