ya, once a modem has been removed from the network VM won't re-register it so unfortunately it is a no go, you also won't get a new one out of VM either because they haven't got any.

As your remark about performance, I was under the impression from several posts I have read that the vmng300 was marginally better when it came to latency (vs the shub) but this was refuted a couple of weeks by someone I trust implicitly. Tbh dude for what you are going to use it for you probably arent going to notice any difference between the vmng300 and the shub. The shub works brilliantly in modem mode and the most important thing you have got to worry about it using a decent router wich can address your requirements regarding stability, dhcp, good wi-fi and I would also suggest dns.

As far as future proofing goes you are better off with the shub because the shub can load balance across 8 downstream channels whereas the vmng300 can only use 4. Many peeps see this as a down side but I am using one on 120mbits and never have any problems getting max speed. I do consider myself one of the lucky few though because I know I am in an area with low utilisation. When we move on to 200mbits I know I am going to need a shub because with the vmng300 I would have to have 4 downstream channels all to myself in order to achieve the throughput.
