Masque, the radio has no bearing on it being a router or not.. I can go into any of my routers and turn off the radio, that though doesn't turn of it's NAT capability and it's that capability that determines if it's a router or not.. On any wifi router you turn off the radio and you end up with a wired router
Just for clarification the VM hub will have 4 components
1# A cable modem
2# A NAT section to it's firmware
3# an internal hub that feeds 4 port and the radio
4# The radio that broadcasts local LAN traffic
By turning off 4# you still end up with a router, what needs to happen is for 2# to be turned off which will then turn the unit into just a moden and hub (with radio)
It's roughly the same as what they do to the business modems when you want fixed IP's, they turn off the NAT side of it..
