Question 1

Can the firmware be updated by the user or only by the isp

Accepted Answer

Don't buy Netgear stuff. It's been over 10 years and they still continue this fraudulent practice. At that time, I bought a cable modem that was recommended by Comcast and within a week, Comcast had changed their frequency but Netgear would not update their firmware nor refund my money. As noted already, each company pointed the finger at each other but none would address or fix the issue. I would never buy Netgear items again. It's their corporate culture. Same with Comcast/Xfinity. Changing their name does not change their poor culture.

Question 2

does this work with Time Warner cable?

Accepted Answer

It’s 2022 and we had an issue with our Spectrum internet connection. The tech that came out said that no matter what speed modem you get or which brand, you’re internet speed will be throttled at 1gb unless you use their crappy modems. I hate Spectrums equipment and I will have to try and find either a work around, or go with a different ISP! We don’t watch enough cable now since Covid that we need to be paying Spectrum almost $400.00 a month to watch content we’re streaming on a Roku device. I just haven’t had time to go over what we’re paying double for as far as HBOMAX and other channels we are watching and paying a monthly fee for on the Roku device.

We have a new fiber optic service that’s getting ready to launch soon called Grande Communication’s , but I’ve heard it’s not great either. Their cable box is a TiVo device and then there’s the changing of email passwords for the new provider. I know a few techs at Spectrum and I’m sure one of them knows how to unblock the internet throttling! I have no issues with opening up their equipment or the box on the street and doing what is necessary to get the best and fastest internet speed possible without being forced to use their crappy modems! I was taking their modems in about twice a month as they kept burning up and they want that rental fee, greedy Spectrum!

I’ve always owned my own equipment except for their cable boxes. I have replaced the DVR hard drive in our current box as it had worn out and they don’t offer the six tuner box in our area now. I guess it’s not a issue if there’s nothing on network television anyway.

Question 3

I've tried to activate this modem on Wave Broadband.  After spending an hour on the phone we can't get it to connect.

Accepted Answer

I just tried with Wave cable in Washington and it doesn't work. I will be returning

Question 4

What chipset does the CM700 employ?

Accepted Answer

Is the issue fixed in these?  anyone have problems gaming with it?  I currently got a puma 6 modem from charter spectrum newly installed with their free ARRIS modem and its got problems with unstable ping times.  Upload download is fine for non gaming use.  Looking for a new one.  IS CM700 okay, or go with CM600 maybe instead, except it costs more and less channel bonding than CM700! ?????????
