Vm are supplying a "hub" (combination modem/ wireless router) only because it became the norm for their competitors (ADSL) to do so. Inevitably, this has given rise to a feeling of entitlement among some customers.
Many of us would prefer if a (multi channel) modem was the only CPE supplied, leaving customers to set up their networks as they think best. Although technically superior, that won't happen even as a paid-for option, for purely commercial reasons
