My guess is that your current modem is DOCSIS 3.0 and to get the speed you'll need a 4.0 modem?
You can probably find a Surfboard DOCSIS 4.0 on Amazon? And the settings from them or somewhere on the webz?
@InvaderGzim ah--thanks! I can confirm current modem is DOCSIS 3. It's been running fine for 6 years now.
I suppose if I do upgrade the modem, my router might become a bottleneck. That's pretty long in the tooth also...
@InvaderGzim zounds. We have 'dark fiber' in my town here, but getting our housing development wired up to it would be muy expensive, so nobody's done it...
