If Ethernet connection on a V6 then that should be fine.
Having just re-read your initial post... "Box keeps recycling start up. Welcome screen - 'Starting up' then sometimes seems to try and download files"
If it's stuck in the reboot/boot-up cycle and won't complete, this will need VM intervention. Although to check that the other obvious bits are covered off..
1: What has changed about your setup? Is it just a regrade of your broadband speed or has any hardware been swapped?
2: Do other devices connected to the same hub, connect online OK? Tablets, phones, laptops?
3: Have you proven/swapped the hub ethernet port & cable as working OK with other devices?
