is that a DG834N ? if so its an ADSL2+ modem/router,

you cant use the ADSL broadband modem part on cable, IF you know what your doing, then you can use the router part as a mear switch and the wireless part as per the 802.11n specification, 11g and 11b speeds.
the slowest part there seems to be the 360 and its 10/100 fast ethernet connection or perhaps 11g wireless if you get one of those.
the basic connection is always
VM BB cable modem<===>WAN port-(wireless)router-lan1<===>switch <===>whatever....
mixing 11g and 11n wireless kit wirelessly connected on the same wireless router slows the faster 11n kit down, so people would be wise to usually wire plug another wireless router setup to work as a generic AP with its DHCPd turned off on that kit...
and one last point, seeing as your talking about using the 50Mbit VM package, do not ever put an 11g wireless router as the first device after the VM bb cable modem
OR you will NEVER get faster than 22Mbit MAX and 15Mbit/s average at best with that wirelessly to and from ALL your LAN connected devices/PCs, and even the wired ports of older cheap kit might also struggle to keep the 50Mbit going even though they say their rated to 10/100 fast ethernet for their internal SOC (system On a Chip)router switchs.
ideally you need an 11n wireless router (with 10/100/
1000 1gig rated ports), or a wired router AT LEAST in that position (or an old PC with a liveCD router package running if you like) , keep all 11n kit to the 11n router, and 11g to an 11g router or wired as the case may be,
