ER605 Freqeuent disconnects
Dear TP-Link,
I have a situation that my ER605 disconnects very frequently. I have restarted the device (and some days before). Today it's unavailable from the controller again. Internet works but yesterday I noticed a degrading of services until reboot.
Not sure what beside reboot can be done. It seems a bug somehow on controller <-> router communications.
Controller is SW on debian: 12.2
kind regards
Jay

Thank you for your post. Have you noticed when this issue first started—did it appear right after a firmware upgrade or after any other configuration changes? Or did it begin following a device reboot? Does rebooting the router provide only a temporary fix? Have you made any specific settings on the router?What exactly do you mean by “degrading of services”? When it goes offline, you can ping the connectivity between it and the Controller.

Thank tou for questions.
I have update that 2.3 firmware a while back (May). The migration for OC200 to Linux controller happedned in 14th August
The disconnects started on 26th Aug.
Reboot fixes the disconnnection issue but it seems to disconnect more frequently now (I have added automated reboot everry night).
Degrading in this context is while ER is disconnect everything runs normally until it seems to reach a point where Internet accss is not longer possbile. First thought it was DNS related but no able to connect the router nothing can be verified.
ER 605 V2 2.3.0
Omada SW 5.15.24.19 9 (on debian)
Not sure what other maybe config mismatch OC200<->SW OC. I used the controller migration wizard.

Hi,
This seems to getting worse today I have 2 switches disconnecting:
also we don't get any IP from the router.
the ER605 is now on daily reboot (4am).
manually rebooting the switches fix it. added option 138 on default VLAN just in case.
cheers

The switches are fine (all power and net cables). The disconnect are nor related to physical stuff. Seems rather an issue of communications with the controller being lost.
I got this message:

@JayinNZ I use an OC200 v2 with latest firmware and get random devices connecting every week or two (I have 13 devices), without any disconnects first. My OC200 seems to lock up often and I think that's the cause of the random connects. I was in the Statistics page once and the interface just locked up. Opened a different browser and still was not able to connect to the web interface, even though I was receiving pings back. After a few minutes when it self rebooted/unlocked up, I received conntected messages.
I know you're using the software controller, but I'd assume they use the same code. I think there's a strange bug in there somewhere that causes a lockup and auto reboot that no one's tracked down yet. I'm in a production environment and can't really do much testing, so I just live with it. Not sure it has anything to do with your issue, but maybe it's related information.
For example, just early this morning I received an email log of just one building's EAP connecting. I checked the Statistics page and at the same time almost all stats have missing data for about 5-10 minutes. After the 5-10 minutes, data comes back to the exact level it was before. Even the user count on every device was exactly the same, so it doesn't look like just one device dropped out. I think the OC200 just stopped recording data while it rebooted.
