Re: Changing VM's modem with a router
 

I use a netgear router with my 255. The router in itself has its own mac and the modem another one. Do I change the mac of the router with the one the modem has?

No, you don't need to do that

Quick note, VM don't use DOCSIS 2, they don't even use DOCSIS 1.1, I believe it was tried but something broke though the support around the cable system is pretty poor until they've finished rolling out the new DHCP servers and even then PCMM servers would be needed to benefit from DOCSIS 1.1+.

They use plain old DOCSIS 1.0 and don't even get that 100% right so no need to worry about state of the art hardware at the mo :)

Unless things have changed a lot most of VM don't know their backside from their elbow when it comes to DOCSIS and the cable knowledge is confined to a relatively few people who either built the stuff or work with it regularly and they are only listened to when excreta hits the fan. The reason for the not too wide knowledge of cable is due to VM being a ******* child of telecomms companies ;)

As ben noted, the modems that are sold now are fine for today's standards. What about 2 or 3 years down the line? What about 2012, when VM are talking about 100 meg services, and is still well within the lifespan of a modem? Do VM replace the modems? Do they risk losing customers by not replacing modems?

As you noted, both NTL and Telewest did allow customers to buy modems. They stopped. Why? I don't know, but I suspect it was costing them more than it was making, so got stopped.
