    It has only been in use for about 3 weeks, but it is running strong and I love the fact it will handle up to 1 gbps in case I ever want to go that high.

    This is a great Modem if you have very fast internet. This is basically for 1 Gig connection's. If you just have basic internet this is overkill. Just be careful if you do get this. It is not a WiFi Modem. It dies not let you connect wirelessly to it. It is also not a router, it will not let you connect anything other then one thing to it. I have it going into a wireless router. That is the only way you can get WiFi. So you have to buy a router if you do not already own one.

    Replaced an ARRIS modem that went out after only 4 months. This was simple to install and activate on my Xfinity/Comcast connection. Price was competitive with on-line price. Works great with Netgear router.

    Installation took zero effort. Performance has been excellent. It easily matches Comcast's speeds (don't we all wish Comcast delivered what we pay for?).

    Top notch modem. Wireless numbers are above the speed tier I pay for. Pay for 500mbps registry get near 700mbps with Speedtests on various devices. Streams 4k hdr from NAS with no issues or latency. Totally worth the upgrade if your speeds aren’t where they should be with your ISP. Wireless AC on ps5 is flawless. Highly recommended.

    No DOCSIS 3.1 in my area, but works great with the 24/4 bonded DOCSIS 3.0 channels. No problem getting my advertised speeds and doesn't get too warm. Seems to have great ventilation.
