Model: SG2210P  
Hardware Version: V5
Firmware Version: V5.20.13

Hello Team,

 

Yesterday evening, I received a notification for a firmware upgrade on TP-Link Switch SG2210P V5.20 (stable release v5.20.13). I applied the update across all sites.

 

After the upgrade, all switches started facing the same issue:

 

  • The switch disconnects and all connected devices lose internet.

  • Internet connectivity is only restored after manually powering the switch off and on.

  • If I reboot the switch from the Omada Controller, the same problem occurs—devices disconnect and do not get internet.

 

Since this problem is happening across all sites after the upgrade, it doesn’t seem to be a single device issue. It looks like something may be wrong with the latest firmware release.

 

Kindly check the latest firmware (v5.20.13) for the SG2210P V5.20, as this issue is affecting all of my deployed switches.

 

Thanks in advance for your support.

All of my switches that updated in the last few days via controller seem to have had that firmware version pulled from the controller, Ethan can you confirm and if we should roll back?

Main: ER8411 x1, SG3428X x1, SG3452 x1, SG2428LP x1, SG3210 x1, SG2218P x1, SG2008P x3, ES208G x1, EAP650 x6 Remote: ER7206 v2 x1, ER605 v2 x3, SG2008P x2, EAP650 x2, ES205G x1 Controller: OC300

Thank you for your post. Please reconfirm that the issue you described occurs only on the SG2210P running firmware 5.20 and that no other switches managed by the Controller are affected. If possible, let us know roughly how many switches are impacted. Have you recently upgraded any other switch models? If so, do they exhibit the same behavior? After you restored connectivity by power-cycling, have you seen any further disconnections or instability?
The switch’s logging buffer and status-monitoring data are lost when power is removed; they are cleared on reboot, so no useful information can be retrieved afterward.If the problem can be reproduced reliably, please do not restart the switch when it occurs. Instead, access the CLI (via console or SSH) while the issue is present and collect the following commands for analysis:

- show logging buffer
- show running-config

Additionally, please observe the switch’s LED status during the outage. What state are the port LEDs and the SYS LED in when the switch goes offline?
