I have to say, I'm having trouble finding a solution that makes sense.. I've always known modems needed to 'rest' between accounts, to let Rogers system get updated and avoid rejected orders. For my customers, that was easy.. Just put the modem at the bottom of the pile
Alternative 1:
I'm semi-serious about a modem exchange service.
Like, you are switching ISPs, so you contact me with your modem make/model. I send you a new MAC/Serial for a different physical modem.
When your activation date comes along (or better the day after) you contact me to check if the replacement modem is active. If active, you come and swap old for new and all is done. If not active... it could be messy.
I'd charge $10, just like the firmware flashing. You'd have a physically different modem, but I would not be able to provide any warranty because it is coming from some other customer--eventually somebody will be upset by that. I'll need to get a couple more DCM475/76 modems to get things rolling.
And the thing about all this is, it is still a huge hassle for everybody, and it ends up costing too much..
Alternative 2:
Maybe Vmedia has the right answer on this one, but the real cost is pretty high..
$5 modem swap fee
$15-20 shipping (two directions)
A lot of time and hassle for customer and company alike
So, ya...
