Title: Great speed and ease of use
Review: Older modem was not working well. This modem helps with higher speed and also works well with our older router. Ease of set up was very good. When I called the customer care to register the device they were very helpful and there was no wait time at all. They explained things very well. The modem is working great so far. I m very happy.

Title: Get a proper setup….
Review: Interestingly, after I purchased this and called the Internet company for set up, this thing did not really work well. It was connected to my Wi-Fi router, but the signal kept dropping all the time, which was very frustrating. I called Netgear support and told them, and they helped me set it up…. Or so I thought. However, we still had tons of connectivity problems. I had to call back a second time to get help. At that time it was mentioned to me that I could get Netgear phone support for about $25 for two years… so, I opted to get it. They probably set the poor support up, initially, so people will subscribe. But, oh well. After the second call to Netgear, we still continued to have problems…. So I called the special cust. service number they gave me. Interestingly, you get what you pay for. When I called this special number, now that I was a subscribed customer, I got a far-superior level of technical support. Come to find out the previous people lied to me, saying my Netgear router was up to date. The guy that I dealt with took care of everything… i mean everything. He changed the an amazing amount of options, and went over everything with a fine tooth comb.. turns out my router was so far out of date, he had to do about 20 updates manually to catch it up. my Internet is now flawless and stays connected all the time.

Title: CM1200 Provides Intermittent Signal - Inconsistent Mpbs, Mostly < 100 Mbps & Frequent < 50 Mpbs
Review: I purchased the CM1200 in August 2020 and received it 8/8/2020. I attempted to connect the device at home as it was replacing the CM500. I have an AC1750 Netgear router that was connected to the CM500 and is now connected to the CM1200. I spent 5 hours the first night working with Netgear and my ISP (Comcast) to setup the device correctly; I was unable to use the activate link and had to call Comcast. While on the phone, Comcast stated because it's a Netgear product, Netgear would have to provide the firmware. However, Netgear's knowledge base states Comcast actually pushes the firmware. It started to feel like I was in the middle between Comcast and Netgear. This should have been an easy experience - plug and play - just like I have done with many other computer hardware.Once the device was setup, it worked well for about a week. The following Sunday I contacted Comcast again because I no longer was getting internet service. Comcast could not see the modem. We went through normal troubleshooting of a power cycle of both the modem and router. Internet service resumed. A little later, Comcast could not see the modem again. Went through the same steps and it was back.Comcast sent a technician out on 8/18/2020. They changed connections outside of my place. Also pushed all the service to one cable connection in my place; all other cable wall outlets do not have cable as I'm trying to ensure all the service is going to where I am connecting my internet and TV (I've been in this place for 4 years and did not have this problem previously until recently).The following Sunday I contacted Comcast again and went through the same steps. The following days I had to restart my modem each morning because I no longer had wifi when I got up to start work. I contacted Comcast 8/27/2020 to further discuss the issue. The first time we went through the normal steps of trying to restart the modem, unplug the modem, attempt to make a connection from Comcast to the modem, etc. Internet service came back... for an hour. An hour later I contacted Comcast again and they pointed me to Netgear. Now I really feel like I'm between Comcast and Netgear and no one taking ownership of the problem.After speaking with Comcast on 8/27/2020, I entered a support case with Netgear. I contacted them on 8/28/2020 because Netgear apparently does not reach out when a case is entered, it is up to the user to contact them after creating a case online. At 4 PM on 8/28, the Netgear technician had me reset the modem, unplug the modem, unplug the router and then reconnect everything. I explained I do this on a daily basis, but went along. When this was done, internet service returned... as expected. The tech said to monitor the internet for the next couple days to see if the problem persists. I told him I know what's going to happen and that I will be contacting Netgear again before a couple days ends. I asked if they could just send a replacement because I've been dealing with this issue for 3 weeks at this point, and he said just monitor the internet service.At 8 PM on 8/28 (4 hours after reaching Netgear) I was on the phone again with Comcast because internet service was non-existent. At 8:30 PM I began my hour long hold with Netgear following up on my open case stating what I told the prior technician that I would be calling Netgear back because I would no longer have internet service. We went through similar steps, however this time the technician had me change a setting on the router.I'm expecting I'll once again be contacting Comcast and Netflix on either 8/29 or 8/30 because the internet is no longer working for me.At this point, I'm caught between Comcast stating that I'm using my own device and they can't support that, and Netgear saying I have 90 days on my service warranty. Meanwhile, I have intermittent internet issues causing me to use my mobile hotspot to work.I will say Netgear tech support has been pleasant once I get through the queue, but I've been on hold 30 to 60 minutes each time I call and then another 30 to 60 minutes troubleshooting. I've also had to repeat many details along the way when I call, however, so that's frustrating.I'm hoping this gets resolved, or I'll have to work with Amazon to return the modem and hopefully get a full refund.
