CM1150v Availability
Hi,
Does anybody know when the CM1150v cable modem will be available for sale? Thanks.

Well, don't know if this has been answered but I just received mine today. Must be pretty fresh becasue I can't find much in the way of feedback out there.
I will say I have Xfinity Gigbit internet service and spent 4 hours going back and forth with different chat agents tonight trying to receive the promised speed. Never could get DOCSIS 3.1 or the proper speed. Xfinity finally gave up and referred me to Netgrear support. BTW, I purchased it from BB and received it quickly. Other sites such as AMZ don't list it as being for sale until the end of January.
Don't get me wrong, I'm sure it will be a fantastic modem, but I'm not off to a good start!
Best of luck.

Please PM me details (current speedtest results, CM MAC, Account #, screenshots of the connection page and event log, and confirmation if you have ever seen Close to gigabit before purchasing CM1150V such as XB6 Comcast gateway)

Will do, thx...

Please continue to share findings back on this thread. Like many others I'm looking to purchase this unit, but it sounds like it doesn't work with Comcast at gigabit speed... Right now, there are only two other options with Comcast. 1.) Lease their modem or 2.) Activate 2 modems, with one being for phone... Looking forward to a "Working" version of the CM1150v product.

Sure will. Since my last post, I've been working with a Netgear employee and have had a couple more go-arounds with Comcast chat support. My speeds are still half of what they sould be (400-500) and I'm not sure I'm any closer to a resolution. I have learned along the way that Comcast chat support can't "see" your modem logs since you own the modem...funny thing is they never asked for results or indicated as much. I offered the results to them and they said it would be quite helpful...ya think? Anyway, I'll post if I even think I'm on the right track to a successful resolution.

As you can see by my previous post I tried speedtest.net and get a totally different speed than comcast test. I guess comcast test is wrong? Moden has been running fine last 3 days :)

Great to hear! I'm still in Comcast purgatory. No real answers yet. You are right, speedtest.net results are usually less favorable than Comcasts. Strange. Early on the Netgreat employee trying to work with me indicated my line was too "hot". He didn't think that was the issue, but after no resolution and many days, I'm not so sure. I've just ordered the Motoroa SB8600 since people seem to have fewer issues with Comcast Gigabit service.
I want to love the Netgear, but don't know if I can survice another fruitless hours long session with Comcast support. I still have few days before the new modem arrives and will continue to check what I can. I just received an order of high frequency couplers and compression F connectors in case it is signal/cable related.
Thanks for the update! Happy surfing...

Can you provide a link to the Motorola SB8600? I can't find it anywhere online. I only see an MB8600. I'd like to compare the specs to the CM1150V. Thanks.

Can You tell me what these error messages mean, I have a ton of the same error in my modem log...
RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW;CM-MAC=78:d2:94:59:70:b0;CMTS-MAC=00:6c:bc:b8:b9:cd;CM-QOS=1.1;CM-VER=3.1;

Hard to say with such little information. My best off the cuff guess would be power level issues on your coax coming into the modem. Not sure if you are using a lot of splitters or what the quality of your signal is but it could easily cause that error. Essentially, your cable modem might be trying it's best to communicate with the CTMS but can't put out enough.
Here's a thread that may give you some more info...
