@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

@testcrash no it doesn't just work in mesh, it's already built into the router, but if you want to mesh other access points from somewhere else it has the option to do that. or use cable like you do.
