EX3220-T0 can't be Mesh agent

PerterQ

When I config EX3220-T0 as a mesh agent, there' s no option on UI, MPro Mesh can enable and only work as controller. How to config it as mesh agent? Or maybe need upgrade firmware? (I can't find where to download firmware.)

I think you should ask your ISP or retailer for assistance.

Because it looks like can't be manually configured to become a mesh agent.
