I've set everything up, but the network seems to frequently freeze when there's heavy traffic, like loading thumbnails or streaming multiple movies at once. It freezes for about 30 seconds and everything becomes unresponsive.
I know there's nothing wrong with the OMV box, because my JDownloader plugin is still downloading fine when the network freezes. I can still access the OMV through the browser. I can access to other networks.
This happens with both Windows and Linux. It freezes with both Samba and NFS.
What could be wrong? Btw this is on Raspberry Pi 3 Model B+
