    I realize there’s a list of compatible modems supported by Spectrum available on their website, but does anyone have any recommendations of one you’ve used and really liked?
    Thanks!

    Haven’t used it personally but I recently recommended this one to a relative, based both on Amazon customer reviews and professional reviews from tech websites.

    The ARRIS SB6141. The brand itself seems very popular and that model in particular. It might be worth noting that my relative’s TWC service only provides a 30Mbps download speed. If yours is over 100Mbps, you might need one of the more expensive models.

    The Arris SB6xxx line is a venerated brand. It’s a cable modem, nothing more. I have the SB6120, the predecessor to the current SB6121, and am quite pleased with it. Since Spectrum has frozen plans for upgrades in much of upstate NY, short term capability is limited, and for getting anything less than about 100Mbps the SB6121 is adequate; it bonds 4 channels downstream and 4 upstream. If you move up to a ‘141, the top capability speed is higher, plus you will bond more channels together (8/4). What this means is less contention for trying to transmit something. Think of using more channels as adding more parallel communication lines, so that less has to go down each line for the same throughput. If you want some measure of “future proofing,” you might want to consider the extra expense of an SB6183, which will bond 16 channels (and allow for up to 686 Mbps downstream). Of course, how many channels actually used is controlled by the cable company, so what bonding you will get is dependent on them. As an example, when I first got my ‘120, only 2 channels were being bonded upstream, until (then) TWC changed their configuration to utilize more.
