A:AnswerThe CM500 is only the cable modem. Unless you plan on only hooking up 1 computer and nothing else, then yes, this will be able to allow that single computer to stream online video's. But if you need/want additional computers/phones/smart-tv/etc to also be able to get on to the Internet, then you will need to purchase a Router - with or without WiFi depending on if you wanted to be able to connect to the Internet wirelessly or not.
A:AnswerMax speed for this model is 680 Mbps. It shouldn’t be a problem as long as your speed cap is less than 680 Mbps and you have verified your ISP is approved for the modem. If you have Gig service or speeds above 680 Mbps, I would suggest something else.
A:AnswerUnder SPECIFICATIONS on the Bestbuy description (click on the down arrow), it says
Downstream Data SpeedInfo
680 megabits per second
Upstream Data SpeedInfo
123 megabits per second
My xfinity cable plan delivers up to 115 megabytes per second download, and about 6 megabytes per second upload, and the modem works just fine.
A:AnswerYes. It does for me in SC. It is on their list of compatible devices. I was able to hook it up and not even have to call to activate it. I hardwired it to my PC and it brought me to a page that self activated it with Charter-Spectrum.
