I have two hubs (C7). While one (the one on wifi) can download the update in seconds (and complete the update), my wired hub download fails (and the download takes a reeeeeally long time).
I've rebooted the hub several times to no avail. Anything else I can try? The failing hub is my primary hub.
Issue 1 - download of latest update fails on wired hub
Issue 2 - download on wired hub is incredibly slow (relative to wifi with 350mbps download speeds).
