IME it's necessary to restart the cable modem to attach a new client but 
there's no need to leave it off for any length of time. Just restarting 
it does it. This has been the case for a few years now, it did indeed 
used to (mis)behave as you say. I'm not sure why it's necessary to 
restart it at all, I think it may be a rather crude way to ensure that 
only one client can be connected at a time.

Someone mentioned VM being useless earlier. Also IME, they are not. The 
actual service is pretty good, and I normally get my full 20Mb/s. If you 
are unfortunate enough to have to call their support line they are 
totally useless though.

In response to another previous comment, I have been connecting to VM 
with OpenBSD and now Linux for 10 years now and I've not had any issue 
with that. Of course, I've never actually mentioned what I'm using, I 
just say "router".
