This is a reach, but has anyone here successfully set up link aggregation? I have the GT-AC5300 and a Synology NAS and I cannot get link aggregation working. It was working on my previous switch before moving to the GT-AC5300. I am using LAN ports 5/6 and enabled the Bonding/Link Aggregation setting, but the NAS is reporting that it is not working. Any help would be appreciated.
