Issue Description/Phenomenon:
Recently we received feedback that after upgrading to ER605 2.1.0 Build 20221230, ER605 will get caught in the loop of adopting- provisioning- configuring under below conditions*, resulting in unstable issue on the network. And this cannot be resolved by rebooting.
*Note that the issue above will only occur when both of the following conditions are satisfied:
-
Omada Controller v5.7 or below manage ER605 v2
-
The WAN connection type is PPPOE
After further investigation and tests, the TP-Link team located the problem is that when the WAN connection type is PPPoE, the newly added MRU function is not adapted to the controller version (v5.7 and below).
Available Solutions:
Case 1:
If you are not satisfied the following conditions, please refer to the Case 2 directly.
- You can still access the Internet.
- When Controller and the ER605 are on the same site, you can perform the following steps when you are on site.
1. Please go to the official website to download the firmware version ER605_V2_2.0.1 Build 20220223.
2. Please change the WAN Connection Type from PPPOE to Dynamic IP on the controller.
Note: After modification, the network will be disconnected for a period of time, you need to ensure that the controller and router on the same site.
3. After the Controller and Gateway Keep in a stable Connected state, you can downgrade the firmware version of ER605 to 2.0.1 on the Controller, and modify the WAN Connection Type back to PPPoE after the downgrading.
Case 2:
If you are no longer able to access the Internet, please follow the steps below:
1. Please hardware reset the ER605.
2. You can use the default IP address 192.168.0.1 to login the management page in Standalone mode, and now you can do the Basic Network settings like WAN Connection Type (PPPOE).
Note: If the LAN Network you used previously is not 192.168.0.0/24, it is recommended that you can modify it to original subnet in this moment.
For example: The original LAN network you used is 192.168.10.0/24, we suggest you modify the LAN to 192.168.10.0/24 either in Standalone mode, it will be very helpful to restore the network.
3. Please go to the official website to download the firmware version ER605_V2_2.0.1 Build 20220223, and downgrade it in standalone mode.
4. Now you can login the controller, and adopt the ER605.
Note: If the controller’s IP address is obtained from ER605 automatically, it is recommended that you unplug and plug the Ethernet cable between controller and Router/Switch to trigger the DHCP, try to adopt the ER605 after the controller obtained the original IP address(like 192.168.10.X) . Then the adoption process will be easier.
