Was that using the same ethernet cable? Ethernet protocol chooses between 10,100 and 1,000 Mbps, so net of the "overheads" 90-100 Mbps usually means the hub and the device have decided that the cable isn't capable of operating at 1,000 Mbps. Try a different cable, ideally Cat 6a or better, we know from other people's experience that the Hub 4 can work perfectly well with the Orbis (good choice). Even if the existing cable is gigabit capable (Cat 5e or higher) they can and do go bad from time to time, for reasons we usually never work out, but could be iffy manufacture, degradation or minor damage such as a poorly made or yanked connector on the plugs.
If a different cable is still limited in this way for both a device and the Orbis, then it sounds like a problem with the hub's ethernet ports.
