Review: Refurbished by desertcart had attractive price - Was delighted to find renewed unit sold at less than half the retail price (which is high because the CM1150 is the only Xfinity approved "customer owned" modem offering phone VOIP as well. Using Xfinity phone app, I was able to set up and activate this modem quite easily. My phone service worked and I measure internet service at 800mb/s... per my Xfinity plan. I streamed a movie that night.. No sweat. I was about to take my original Xfinity Gateway back to the store when suddenly I noticed internet was struggling. eg. my wife was on zoom chat that was halting. I was using google translate and it was taking a minute to do simple translations. Within 2 hours, all internet was dead. Phone stopped working too. I unplugged the CM1150. Put outside to quickly cool. All to no avail. Re-starting failed to get any functionality back. I then re-activated my Xfinity gateway box. (BTW: That cannot be fully completed using Xfinity App. Phone worked, but internet data was inoperable. That's because special "codes" at their office must be reset before Xfinity will deliver broadband data to that original Gateway modem. Only a live chat session or getting an agent on the phone can get this done). Once up and running, the Xfinity gateway was working normally and reliably. I'm going to hazard a guess. This COULD be an issue of marginal signal strength over the Comcast cable. I am skeptical anything actually broke in the Netgear CM1150. I've had the Xfinity gateway for 2 years and internet loss was only very occasional. My hunch is that the Xfinity equipment may work better as depleted signal levels. I'll probably hold onto the Netgear modem and re-try it in a month- would prefer not to pay the $15/mo rent. UPDATE (2.21.2024) I've been monitoring signal levels in the Xfinity connection status. The signal strength in my family room location is lousy... varying between -15 dBmV and -10 dBmV depending on day, time of day.,etc. I built up a location to place the cable modem very close to my home's Xfinity cable ingress & powered distribution box in my basement, running CAT5 + Phone wire to first floor wall jacks for router & phone base. The Xfinity Gateway experienced 3 - 4X higher downstream signals at the basement location compare to distant family room. Then reinstalled & activated the Netgear CM1150 . Everything came up working within minutes. With just 3 feet 75 ohm coax to the CM1150 from Comcast powered splitter, signal levels between -3 and +1 dBmV are reported by the CM. That's plenty of margin to deal with daily variations that will be in 5 dBmV range. Feeling confident I can dispense with the Xfinity equipment and rely on the Netgear CM. Revising my rating to 5*. Very pleased!
Review: Couldn't self-activate on Spectrum, but a quick call fixed the issue - This renewed modem was such a bargain compared to new. I wanted to upgrade my internet to Gig internet and needed to upgrade my modem. Bought this renewed version (it looks like new) and I am glad I did. While I was unable to self-activate on the Spectrum activation site due to an unknown error on their end, I called and they activated it within a minute or two. I don't have any problems with it and am now enjoying 900Mbps+ speeds. Yaay.

## Questions & Answers

**Q: I bought and finally connected. I can only get 1 of the 4 ports to work at any given time. It doesnt mater what port I plug in 1 works other no**
A: The additional 3 ethernet ports are reserved for port aggregation, which is currently not supported on the CM1150V.  I guess you would call them reserved for future use.  The CM1150V does not include built in router.  Most ISPs, like Xfinity only provide a single IP address with your service, so you would not be able to get multiple computer or other network devices to work without a router connected your modem.  What you would need to do is connect a router to one of the ports on the CM1150V, then connect your devices to the router.

**Q: Will this work with optimum**
A: Hands down, the most I’ve laughed reading answers to a simple question.. and anyone looking to save themselves a couple of hours of researching between Reddit/ forums; yes this modem is actually one of your safest bets with optimum. In short, where you live is what determines how optimum delivers that Internet to you and if you’re like me getting it over coax and fiber (“gigabit passive” I think? You can tell by if your plan is a big number over a much smaller number i.e ‘1000mbps download  /50mbps upload’) it’s a very annoying / complicated way to deliver those speeds, or at least for those who just want a simple reliable upgrade to optimum’s turd modem, and this one of all seems to be the least problematic across the board. If you end up getting this and it just doesn’t happen to work well in your area, don’t worry… I’ll save you the time and let you know that as an optimum user your best three future-proof modems come down to this one (Netgear cm1000, 1100, or cm1200), the arris sb8200 (tried it and didn’t work for me), or the Motorola mb8600. And since I’m trying to be as informative as possible and answer the majority of questions that eventually come after the main one, you should know that before you rule out a model actually working for your Internet setup, you WILL get a lot of optimum representative on the phone who should but don’t necessarily know or maybe have all the info to properly push the RIGHT settings to your modem. I don’t mean any disrespect to them by that because it is complex stuff, but for your own mental health and time, if the person you’re speaking with seems unsure or struggling a lot to help you, or even worse lie to you and tell you it can only work with their equipment, just Bring that call to a close as fast as you can and try again with somebody else. try to get on the phone with a representative who seems pretty confident in what they’re doing and sound more familiar with what you’re trying to accomplish. If all else fails, you could simply have a defective device or just try a different one mentioned above.. it’s a lot I’ve said to answer what we all thought was supposed to be a very simple yes or no question but at least you just have to get it right once. I’m no expert and anyone please feel free to correct me but it’s what I’ve best been able to gather over the past week and it’s our home Internet we’re talking about here. (Definitely not going back to fax) Optimum’s is just inconveniently a pain but not many of us get to choose. Thumbs up if this helps as this is my first answer on Amazon in all the years I’ve used it haha good luck! :)

**Q: Where do i find the devises user id and password?**
A: It's printed on a label on the modem itself.

**Q: Can i attach a wifi router and a switch to this?the wifi routrer would of course be for wifi. the switch would be to serve my wired lan.**
A: Yes, you can attached a WiFi router to it.  You can then attach a switch to either the Wifi Router or the Cable Modem.  If you attach it to the cable modem your wired LAN will be a different network.  If you attach it to the WiFi router you could have everything on one network.
