@Matthieu27 I edit my post, There is no beta to OC200 so you hae to remove router from controller and install in stand alone, then readopt router after upgrade to 1.0.4

@Matthieu27 If you have a hardware controller, it can only be installed stand alone, with a software controller it should work if you have 5.9 or newer as for OpenVPN, it is not fixed in 1.0.4

@SoloAdminEh make sure that you have enabled vlan on the ER8411, there are many ports on it and it is easy to forget to check vlan on the ports you need. so my recommendation is check all VLANs make...

@Lubomir you can find it here, it is only for windows https://community.tp-link.com/en/business/forum/topic/612908

@SnakeSystems Yes, I think it's the easiest. log in to the controller with a local account, unbind tp-link id and activate with a new account.

@Chirs I use a Ubiquti UC-DAC-SFP+ between a ER8411 and SG2428p Swith, but on ER8411 10GB was deafult and I have to set 1GB manualy, mybe there is somthing semilar on your switch
