Gigabit modem with multiple ports versus gigabit modem with 1 switch and a gigabit switch
Hello! I am looking at moving to gigabit internet, and thus need a compatible modem. I was looking at the CM1000 and noticed that it only has 1 port on the back, I believe another variant has 2 ports...
The netgear C7800 is compatible with gigabit. I've used it and it works great. I'm still not a fan of combo devices because if the modem or router part fail, the whole thing fails. Plus you're locked into trusting ISP's for updates. Which doesn't happen. But they are nice for easy of use and simplicity.

the other one I i know of is a Arris SBG8300 but it hasn't been released yet.
You can always go with a modem (cm1000 or cm1100 support gigabit) and add a decent router. Plus you have the option to upgrade routers as features get added without having to replace modems as well.
Gotcha, I don't see that on their list.. any guesses as to why they only show a few supported ones? This list is how I ended up on the cm1000 trail initially.
Not sure why it isn't on their list. Maybe they want people using/renting one of their gateways? Its comcast.
I've had one and used it solidly for quite a while on comcast before I went with a cm1000 and orbi setup. I pulled full gigabit speeds and didn't have a single problem with it.
Gotcha, if I did go the cm1000 setup, what "search criteria" am I looking for when I shop around for a router? Just gigabit compatible?
Most current and new routers and even older routers back 10 years ago are all 1Gb WAN/LAN supporting on there RJ45 ports. Actual thruput speeds will differ. Just remember, the ports on all routers are a connection rate of 1000Mb or 1Gb, this is just a connection rate between the router and wired devices connected to the ports. This is not actual bandwidth or data flow thru the port. Older routers don't actually support data thruput up to 900Mb+_ on the WAN to LAN test. Newer routers in the past 5 years do, depending on model.
You can check out smallnetbuilders.net and find reviews and test results of all the routers they test and see how the fair and what they actually do as far as data flow thru the WAN to LAN.
