Needed tech support because I had a Comcast phone modem and would not allow self set up.

Mind you, I had to read through the instructions twice and had to call tech support before I was done, but for me it was quite an accomplishment

A small problem on start up was quickly remedied by tech support

Their tech support told me I need DOCSIS 3.1, which is why I purchased it, but once I tried it and found only poor quality connection speeds, their upper level support told me that they don't actually work with DOCSIS 3.1

I tried calling Netgear's tech support line a couple of times

Spent 2 hrs on the phone with tech support and could not get a return address

Finally one of Spectrum tech support team fixed my issues

Even if it does, and we got a defective unit, a two hundred and thirty dollar modem that took 6 hours of tech support to simply fail miserably at being a modem is probably not worth your time

I was told about the MESH technology by my ISP tech support and it is performing as promised.

Despite all of this, the tech support rep refused to help me or stand behind the reliability of NETGEAR's product

Stopped working after 11 months, couldn’t get through to tech support

Tech support is awesome.

I had to call and have it manually-provisioned by their tier-2 tech support, but it was a quick process and they got it up and running in about 20 minutes for me

Netgear tech support is phenomenal

Netgear only offers 90 days of tech-support for free and then you have to pay a monthly fee

I called Netgear Tech support, and received a less than acceptable response

Netgear tech support will only replace a CM500 with another CM500.

Disconnect the old modem, give tech support the MAC and Serial number located on the bottom of the modem, connect the new modem, and then they send a signal to it and it works.

Even Spectrum tech support could not solve my issues

Restarting the modem does not help, either using the power switch, or by having Xfinity do it thru an automated phone call, via tech support, or thru their

It was up and running in minutes; the tech support guy was amazed that it was working instantly; they usually need to tell people to wait an hour or so.

Tech support refused to answer the simple question and instead made me run through a series of resets and reboots only at the end to confirm that the blinking power light was an issue.

after spending about an hour on the phone with the very nice tech support person, i ended up being told that it's not supported and i had to plug my old modem back in.disappointing but i'll make sure to do more research next time.

I called Netgear Tech support and was told that those issues have been resolved through firmware updates and are are no longer valid

A phone call to Comcast tech support worked (it's a crappy set of prompts - nothing about activating a

Tech support ended a month ago so now I have to pay to figure out what’s wrong??Waste of money, would not recommend to anyone using Optimum.

Functionally, this works very much like what it is replacing, the principal difference being that it was also replacing the existing cable modem and that involved a few phone calls to tech support at the cable company as I had to provide them with a little necessary information

but i was on the phone with the cables tech support who couldn't tell me whether or not the problem was my modem or their line (like always)

Cable tech support took 12 separate phone calls and countless hours to get it right

Tech support refused to answer the simple question and instead made me run through a series of resets and reboots only at the end to confirm that the blinking power light was an issue.

Even Spectrum tech support could not solve my issues

I didn't even have to call tech support and read them my MAC address

Worked with Tech Support for install/activation because we have split incoming coax to serve both a stand-alone Internet-only modem and an eMTA for digital voice-only.

Called tech support, gave them Mac and worked immediately.

I tried The tech support and 1st, it’s all Indian based

we have experts on all electronics” tech support.

Through Netgear tech support, I found out it is not due to hardware issue, it was due to loss of information from ISP (Spectrum)

That being said, with help from tech support, I was able to connect to a COX network as they have similar models which they offer

Despite all of this, the tech support rep refused to help me or stand behind the reliability of NETGEAR's product

After spending 3 hours with NetGear on tech support they finally dropped the pearl that "..your router must be broken."After dismissing them, plugging back the old modem, calling Xfinity again (..and, voila, having the modem up and running in literally 2 minutes...

I spent multiple hours on the phone with Comcast before I finally got tech support, and did a 3 way call with Netgear..

Netgear claims that this modem (CM400) supports up to 340 Mbps on the product box and their website and even after a phone call to their tech support today they repeated the same thing

I hit a bit of a snag trying to get it activated because their tech support kept telling me that it is not certified and will not work on business class

The 3 stars for technical support was only given since I have not had to reach out to tech support for any issues

This modem will not connect with my Linksys Velop mesh system without hours of tech support and hard coding MAC addresses, etc.

Tech support said they'd never seen this router before

So, we paid $250 for basically (or as Netgear tech support put it) a "dumb" plug-n-play modem that can't really be controlled by Xfinity (or yourself), other than RESTART and REFRESH, for which you have to call in to initiate

whereas complimentary "tech support" is provided by NETGEAR for only 90 days from the date of purchase

Tech support not rated because we didn't need it.

I had reason to call tech support when I ran into a problem with this modem.

Tech support with barely intelligible accent suggested a solution unacceptable to the ISP

Bolted right up no tech support needed!

Just had to call tech support to have them activate the mac address.

As usual the swap was easy as you simply phone tech support and tell them that you have a new modem.

One star removed as there is virtually no support to be had from Netgear, tech support is in India, they are very difficult to understand and not helpful at all..if you anticipate relying on their assistance, seek another modem brand as their tech support is awful.

Multiple calls to tech support at Comcast

It was really easy to install and would have been super easy to get up and running with tech support if it were compatible, so I give it five stars.

I did not rate Tech Support because I did not need it

It has a very strong WiFi signal, and tech support is excellent

First I want to say that Netgear's Tech Support is phenomenal

At first we thought it was our provider, they sent a tech support and said our modem wasn't working

the tech support guy from my ISP said he would be shocked if it was my modem since I'd only had it a year

I had to call tech support and was easily guided through my situation ( due to my lack of tech skills

During the install there was a minor hiccup where the device wouldn't connect to the cable network, after contacting Netgear's great tech support, the issue was found to be an issue with Cox (who had originally blamed it on Netgear), and they gave me the exact error code to give back to Cox

Ended up calling tech support and they said it was most likely a bad modem....

One star removed as there is virtually no support to be had from Netgear, tech support is in India, they are very difficult to understand and not helpful at all..if you anticipate relying on their assistance, seek another modem brand as their tech support is awful.

Now, if you had netgear tech support you will know their tech support has something to be desired with the heavy accent from their support staff

I also haven't needed to contact tech support, so I won't provide a rating for that either, as it was a very intuitive and straightforward process.

n’t disappoint either

n’t support there 500 Mbps speed.

(works fine on my cheap T-Mobile hotspot).

n’t had issues with fluctuating signal, and I believe this is our magic fix

DPC3941T did!So far so good!

n’t had any problems at all.

The first ID’s on the box were different than on the modem and didn’t work!

I WOULD NOT BUY THIS MODEM AGAIN, AND WOULD STRONGLY RECOMMEND AGAINST ITS PURCHASE.It’s always difficult to say if a device providing poor connectivity is due to the vendor (e.g. Cox, Mediacom, etc.) or the hardware

We use ours with the Orbi router and it’s very nice being able to turn kids WiFi’s on and off or use the timers and parental controls.

It is the appropriate mb/s for the internet speed I have, and it does its job well
