I only know of two 32x8 cable modems and both have the same latency problem. SURFboard SB6190 and Netgear CM700. Is there more than just them 2? I am wary of buying a 32x8 modem after reading the reviews and seeing the problems of these modems.
I wonder how much longer it will be before they start selling them.Intel PUMA based 32x8 modems have the latency issues, I would skip this generation and wait for DOCSIS 3.1
There is a firmware that fixes ICMP IPV4 packets only, so you will still have latency in UDP/TCP and IPV6.
