In the latest release (18.104.22.168) we added Ethernet port settings on the Networking page. If your hub's pages are slow to load or sometimes the hub doesn't load at all, it may be that your network switch is unable to properly auto-negotiate the hub's Ethernet speed,
If that happens to you, connect to hub, then head to "Settings". Select "Networking" and scroll down to "Ethernet Speed" section. Switching to "Fixed 100mbps" may resolve your user interface problem.
