@Mesaque per use dpi can be found here. I don't know which controller you have but on verion 6.1 it is here. you can also find it if you click on the client and manage client, then statistics

@Mesaque If you want to filter by country, it's pretty simple. Go to router acl, then create acl allow or deny in the same way you filter other things. You can create location group or enter country...

@jra11500 I think this is fixed in controller version 6.1

@testcrash no it's not close to the ER8411, looking at the specs I think they match up pretty well.

@Walri01 Look at the release notes. Not all require the minimum version to install.

@Walri01 upgrade all firmware to the latest, there have been a bunch of fixes, including dhcp
