Xfinity speed warning - CM1150V should support it with channel aggregation?
I've been happily running on Xfinity 1G plan on my own Netgear CM1150V for a while (needed that particular modem because we have a voice line). Xfinity just sent a notice that our plan has upgraded to 1.2G and the CM1150V needs to be replaced because it doesn't support it. However, in reading the specs I don't think that's correct - the CM1150V looks like it ought to support up to 2G on the coax side, but would require channel aggregation turned on in order to do so because the ethernet ports are only 1G each. The downstream router/access point would also need to support using the aggregated links. Is this correct, or am I missing something obvious/important here?

Hello and thank you for taking the time to reach out to us here on our Xfinity Forums! Reviewing that modem on our compatible devices it is only rated to receive 948 Mbps on our network.

Thanks XfinityBillie - also looks like my internal wireless router wouldn't have been able to handle the aggregated channels on the WAN side either, even if the modem did support the higher tier speed. I'm overdue for a hardware refresh anyway, time to do a little shopping. :-)
