Below are all the modems on the Charter Spectrum Approved Modems List and that can be bought at Amazon, Walmart or Best Buy. We've gone through all of them to find the ones that can be purchased at major retailers.
If you're paying $7 a month to rent a modem from Charter Spectrum, that's $84 a year or $420 over 5 years. You can buy a new one for less than that. There are used ones that will pay for themselves in less than 3 months.

DOCSIS 3.0 and DOCSIS 3.1 Cable Modems
Cable Modem Buying Tips and FAQ's
All Charter Spectrum Internet Service subscribers, buy any of these DOCSIS 3.0 or DOCSIS 3.1 modems. If you subscribe to plan up to 100 Mbps, choose a modem with 8 downstream channels to maximize your speed. For plans up to 300 Mbps, buy one with at least 16 downstream channels. For higher speed plans, but a modem with 32 downstream channels. If you have telephone service with Charter Spectrum too, these won't work.
This list also includes minimally qualifed modems. You can read more about that here: Minimally Qualified Modems
All of these modems are high quality and have pretty much the same features, except for number of downstream channels and those with routers built in. So don't worry too much about deciding which one to buy.
Price should be a main factor in your buying decision. Buy one now and start saving those rental fees!

Minimally Qualified Modems
This is Spectrum's statement about minimally qualified modems that can be found here: Charter Spectrum Approved Modems List
"You may also choose to buy a modem that has passed minimal testing to confirm that it won't cause harm to our network. Though permitted for use on our network, we recommend against using Minimally Qualified Modems because they haven't been tested to confirm their ability to deliver your purchased internet service speed."
"Note: If you attempt to install your own device from our authorized modems list that doesn't meet the speed tier you ordered or if we can't determine the device qualification, you'll get a message that notifies you of this, and you'll be asked to acknowledge this before you proceed."

I have Spectrum phone and internet service and an Arris TM502G. If it makes sense I would like to replace it with something that will be approved for Spectrum Phone and Internet.
I see their list but I can't tell if they are for BOTH phone and internet. All I see is internet.
Can anyone help this novice?
Thanks in advance. Michael
Try looking into something like Ooma Telo for your phone service. Much cheaper than Spectrum. Then get a modem only device for your internet.
Get any of the approved 16x4 modem only devices. The Netgear CM500 is a great choice. The Motorola and TP Link ones are good too. Cheaper than the Netgear but i'd go with that one.

Replies would be appreciated. Thank you.
Some modems with intel puma chipsets have had firmware updates. Not all of them from what I read.
I had already bought a netgear modem (cm600), but I may return it and try one of the modems from spectrum. Spectrum installed the wrong modem. I am on 400 mbps, but only receive 200 mbps. I plan to visit spectrum to rent one for free. If it turns out it causes me problems, I will go back to the Netgear modem which is still brand new and not open.

If that checks out, try putting your computer next to the Apple TV and try doing a speed test over Wifi and see if you have enough speed. If not, its a wifi problem and not the modem.
I had a Roku box using wifi that had terrible video quality. Moved the box 6 inches from behind the TV and Presto! perfect video.
Anyone else with suggestions?
It has the modem inside and recommended on Charters website, I tend to wonder are they telling the truth just do not want you to buy your own, so they loose out on rental as I am paying $10 per month !
I'd like to purchase a WiFi router/modem [one unit] that is compatible with HD Spectrum/Charter.
Best Buy has it for $149.99 right now
I'm currently trying to make the same decision. It appears as though the chipset and these 6190 may have issues with latency though.
